STANDARD ACCESSORIES

 No accessories are included with this module

The XR-3 TS2 module represents a new standard in satellite identification capability. Rather than

loading a limited set of satellites or a large number of channel plans to select from, the XR-3 TS2

module holds all of the compatible satellite transponder information for the entire continent.

You just tell it where you are, and what type of system you are connected to, and the XR-3

accesses all compatible satellite transponders visible to that system. The basic operation

becomes extremely simple:

Left arrow button – goes to next orbit east

Right arrow button – goes to next orbit west

Up arrow button - next higher transponder

Down arrow button – next lower transponder

Connections

1) ODU / LNB - connects to the LNB (or receiver side of a multi-switch)

2) IDU / IRD - connects to the IRD (receiver or modem) – NOT REQUIRED

ODU / LNB Connection

The ODU / LNB connector has two functions:

 Supplies voltage to power the LNB

 Sends commands to control multi-LNB head or external multi-switch

 Receives RF signals coming from LNB output port or multi-switch output port

IDU/ IRD Connection

The IDU /IRD connector has two functions:

 Measures voltage supplied by the IDU/ IRD

 Allows voltage supplied by IDU / IRD to power the LNB extending the battery life of meter

However, the meter itself is always powered by its internal battery or by the external AC to DC

switching power supply while connected to AC power.

Note: In order to prevent damage to the meter’s circuitry, do NOT input more than 30 volts to the

XR-3’s TS2 module.

2. Run Screen

The Run Screen displays valuable information used when pointing a dish or testing an L-Band

network.

1) Selected satellite

a) Change satellite with left and right arrow keys for single LNB systems (or with the LNB

soft key when connected to multi-LNB systems, see Multi-LNB Systems below)

b) Satellite name is on the top line

c) Orbital position is shown at upper left

2) Lock status

a) Search – when searching for a matching signal

b) LOCK – when signal lock is obtained, this indicates you MIGHT be pointed at the

selected satellite, but you must use the ID soft key to confirm the satellite.

3) Transponder information (upper right)

a) Transponder label

b) Frequency (L-band or downlink)

c) Polarity (RGHT, LEFT, HZ or VT)

d) Voltage provided to LNB (13, 18, 21, or 29 volts)

4) Signal Level

a) Left bar graph (with peak hold center line)

b) Numeric value in dBm, dBmV, or dBµV

c) Scale: -75 to -15 dBm (-26 to +34 dBmV)or (+34 to +94 dBµV)

5) Signal Quality

a) Right bar graph (with peak hold center line)

b) Numeric value as IRD equivalent or C/N, Eb/No, or Es/No in dB

c) Scale: 0 to 20 dB C/N

Soft Keys

1) SYST - transfers to the System Setup Screen

2) ID - starts satellite identification verification function

3) AZ/EL - transfers to the Azimuth and Elevation Lookup Screen

4) Polarity - displays or selects polarity and LNB voltage

5) LNB - Turns LNB power on or off (displays present state) and selects switch ports

6) MENU - transfers to the Main Menu Screen

Changing Satellites

The left and right arrow keys switch to the next east or west satellite visible to the selected LNB.

If the LNB polarity can be switched (dual polarity LNBF), the first priority id transponder will be

used and the polarity may switch if needed. If the polarity cannot be switched (single polarity

LNB with dedicated feed horn for VSAT or commercial TVRO applications), the selected polarity

will be maintained.

If you have selected a multi-LNB system, the selected satellite will also change when you use the

LNB soft-key to switch between LNBs. (See Multi-LNB Systems below.)

Changing Transponders

The up and down arrow keys take you to the next or previous transponder in the same satellite

(actually in the same orbital slot). If the polarity is locked (via single polarity LNB type) then you

get the next transponder of the selected polarity. Only transponders visible to your region are

used.

Polarity

If the LNB supports polarity switching (i.e. dual polarity LNBF) or is stacked, the polarity key is

disabled (as shown above) and the transponder selection determines the polarity.

If you are using a single polarity LNB, the polarity must be selected (to match the orientation of

your feed horn) using the polarity key (top right soft-key) and the transponder selection is limited

to the selected polarity. See figure below.

Multi-LNB Systems

When the selected LNB system supports multiple LNBs or multi-head LNBFs via the switch

setting, the LNB ON/OFF button also controls the switch setting. Upon pressing the LNB power

soft-key, the meter sends a switch command to toggle to the next feed horn and the satellite is

automatically changed to the one normally used for that port.

XR-3 TS2 Module Operation Manual XR-3

Page 9 of 67

For example, the Dish Network Dish 1000.4 West system is typically used with the 110°, 119°,

and 129° satellites. When you press the LNB power soft-key (middle right side of LCD screen) to

select LNB1, the meter automatically selects the 119° satellite. Press it again to select LNB2 and

the 110° bird is selected. The third press gets you to LNB3 and the 129° bird.

Satellite Identification

Satellites are identified by obtaining locks on one or more transponders. To obtain a lock, the

frequency, signal type and symbol rate of the transponder must be known to the instrument.

These combinations vary enough between the satellites that they can be used to identify the

satellite. Unfortunately, one transponder is not always enough; there may be another satellite

using the same combination.

ID Verification

Unlike other meters, the XR-3 has the ability to check one or more transponders looking for a

match on a combination that is unique to each satellite. This is what we call the “ID Verification”

feature. It is initiated when you press the ID soft-key (middle left side of LCD screen) on the Run

Screen.

When you change satellites with the left/right arrow keys (or with the LNB power soft-key if you’re

connected to a multi-LNBF system), the default transponder shown will be one of the

transponders used in ID Verification. Once you get a lock and peak the dish on this transponder,

press the ID soft-key and the unit will check any other transponders needed to confirm the

identification and display either “VERIFIED” or “ID FAILED”.

XR-3 TS2 Module Operation Manual XR-3

Page 10 of 67

Satellite Scan

If you have peaked up the signal level (left bar graph) on a satellite, but either don’t have a signal

quality and lock or get an “ID FAILED” message when performing the ID Verification, the XR-3

can try to determine which satellite you are pointed at by performing the ID Verification on

different satellites sequentially. This is called the “Satellite Scan” feature.

To run a Satellite Scan, press the ID button to verify the selected satellite. If that succeeds, there

is no reason to run the Satellite Scan. If that fails, there will be a “SCAN” button on the “ID

FAILED” Error Screen, press that and the scan begins.

The scan will start from the selected satellite, presumably the one you are looking for, and look to

the east and west one satellite at a time until a positive ID is found or the horizon is reached, or

you abort the scan.

Field Guide Updates

Unfortunately, the satellite identification process is only as good as the transponder definitions

that are used. And these change often enough to make the job challenging. That’s where Field

Guide updates come into play. As we update our software database, we post the revisions on

our web site, which you can download into your instrument. See the section on “Updating Your

Meter”.

Our software database is updated from information gathered from the service providers, other

web sites, customers, and our own testing and research. If you know of any omissions or errors

in our database, please contact us so that we may pass on what you have learned.

The Hardware version and installed versions of Field Guide, Software, and Postal Codes are

displayed in the versions screen. You can access this screen by going into the Menu then

Versions.

3. Main Menu

The MENU button takes you to a menu of all of the XR-3 screens. Some of these screens are

also available via soft keys from the Run Screen.

All of the functions are available on the central menu using the up/down and Enter keys. Some

functions are also available via soft keys as a shortcut. “Exit” takes you back to the Run Screen.

The functions are described in the sections that follow.

4. System Setup

You must use this screen to specify the type of system you are connected to and where you are.

This step is essential: the XR-3 calculates all frequencies based on this information and

displays only the transponders that can actually be received by the selected system in the

selected location.

To enter the System Setup, press the SYST soft-key from the Run screen or use your up/down

arrow keys to select ‘System Setup’ from the Main Menu and then press Enter.

XR-3 TS2 Module Operation Manual XR-3

Page 13 of 67

This screen is a simple menu selection. Use the up/down arrows to highlight the selection you

want to change and press ENTER.

The system selection actually selects three items:

1) Region

2) LNB system

3) Switch type

Due to the large variety of LNB systems in use, the LNB system selection is divided into three

levels:

1) Service

2) System

3) LNB model

Because you will not need to change the region very often (if ever), the second option is

highlighted by default. You will need to use the up arrow key to change the region.

XR-3 TS2 Module Operation Manual XR-3

Page 14 of 67

The LNB system also defines a default switch type, so this selection is also normally skipped.

However, you may override the default switch type if desired.

Regions

When the unit is shipped from the factory, it will have the latest information for North America

(except for the Hawaii region, which is found in the NE Pacific Field Guide) loaded into it. If you

are using the XR-3 outside of North America, you must download a different Field Guide from our

website. See the Updating chapter for details.

You must select a region within the Field Guide that better identifies the area where you will be

using the meter. If you are not sure of which region you are in, it probably doesn’t matter

because there is significant overlap in the regions. For example, the NE Continental US region

extends as far south as South Carolina and the SE Continental US region extends as far north as

New Jersey.

The region selection is necessary because transponders are pointed only at certain parts of the

globe and the XR-3 will use just the transponders that are pointed at your selected region.

Services

The service selection groups the LNB/antenna systems into small sets of choices. The available

services may change with Field Guide updates.

XR-3 TS2 Module Operation Manual XR-3

Page 15 of 67

Systems

The system selection lets you pick the type of system within the selected service. In some cases

this is the final LNB model selection. In other cases, the system will be broken down further by

the LNB model selection.

XR-3 TS2 Module Operation Manual XR-3

Page 16 of 67

LNB Model

The models listed will depend on the system selected. For example:

Switch Type

Many multi LNB dishes have a switch that is internal to the multi-LNB head. Other systems may

use external switches. When you connect the XR-3 to an external switch rather than directly to

the LNB, or when you connect to a multi-LNB head, the XR-3 must know what switch type is

connected so it can send the proper type of command to control that switch.

The switch type is usually selected automatically when you pick an LNB Model, but you may wish

to change it or select another external switch. If you are installing a system that does not have a

switch, you may need to select “none”. (Note: additional switch types may have scrolled off the

end of the screen. Use your down arrow key to view these.)

XR-3 TS2 Module Operation Manual XR-3

Page 17 of 67

5. Options

There are several options you may select to personalize the operation of your meter.

To use this screen, highlight the option you want to change with the up/down arrow keys and

select the value you want with the left/right arrow keys. Press EXIT soft-key when done.

Signal Level

The signal level may be displayed in dBm, dBmV or dBµV.

Signal Quality

The signal quality number may be displayed as one of the following:

C/N (carrier to noise ratio) in dB

IRD (receiver) equivalent number

Eb/N – Energy per bit over noise energy per hertz in dB

Es/N – Energy per symbol over noise energy per hertz in dB

IRD numbers for DIRECTV range from 0 to 100. Dish Network uses two scales: the old scale

from 0 to 125 and a new scale with much lower values (approximately 0 to 85).

Frequency

The frequency may be displayed as either the L-band frequency, which the meter is tuned to, or

the downlink frequency transmitted by the satellite. Both are displayed in MHz. The L-Band

(900-2150 MHz) frequency is the frequency of the signal after being down-converted by the LNB.

Sounder Option

Peaking via the audible tone can be done in two ways: “tone-on-lock” and “peak-o-matic”. The

“tone-on-lock” method uses the following:

1) Slow beep - the function is on

2) Fast beep – the signal is locked

3) Solid – the signal is locked and at the highest level yet seen

XR-3 TS2 Module Operation Manual XR-3

Page 18 of 67

This method works well when the dish is close enough to obtain a signal lock. If you have trouble

finding a lock however, you may want to use the “peak-o-matic” method:

1) Slow beep – the function is on

2) Fast beep – the signal is at least 5 dB higher than the lowest level seen

3) Solid – the signal is higher and at the highest level seen so far

Note that the peak-o-matic method does not indicate a lock. It allows you to peak the azimuth and

elevation even before a peak is obtained.

In both methods to fully peak the dish, you must move it in one direction until the signal is found,

and continue moving it until you move past the peak, then move back to the solid tone.

Shutdown Timer

The unit can be set to automatically shut off after 5, 10, or 15 minutes with no buttons being

pressed. This timeout can be disabled by setting the option to “none”.

Frequency Deviation

If you select Freq Dev = YES, the lower left corner of the Run screen will display an estimate of

the frequency deviation or drift of the LNB. The XR-3 is capable of locking onto a signal up to 

10 MHz from the frequency defined for the transponder. A frequency deviation of more than 2

MHz (2000 kHz) may indicate a problem with the LNB. High or low temperatures will cause an

LNB to drift and an LNB that works in normal weather with a significant drift may fail to work in hot

or cold weather due to the additional drift. Please note that the Frequency Deviation feature will

only work while you are receiving a LOCK on a satellite.

IRD Calc

As mentioned under “Signal Quality” above, Dish Network has an old IRD quality scale from 0 to

125 and a newer scale with much lower values (approximately 0 to 85). Use this option to select

which scale to use. The default is “New”.

PoP Delay

If you notice transponder results missing from the PoP Scan reports, you may need to introduce a

delay into the Proof of Performance scan. The value entered in this field is the number of

samples taken if a LOCK isn’t obtained. The unit takes 3 samples per second. If 0 is entered in

Freq Dev

XR-3 TS2 Module Operation Manual XR-3

Page 19 of 67

this field, the PoP Scan will operate normally without any delay. You may experiment with 5, 10,

15, or other values.

Key Beep

By default, key beep is on and you will hear an audible “beep” when any buttons on the meter are

pressed. You can turn off the key beep if desired.

Display Theme

By default, display theme is ‘Light’, with a white screen background. You can select the ‘Dark’

display theme to enable a black screen background, if desired.

Preset

Pressing the Preset soft-key in the Options menu will return the XR-3’s TS2 module settings to its

factory default settings (will erase any stored postal code or latitude and longitude setting, will

return the RF signal level field to its default dBm value, will return the signal quality field to its

default C/N value, etc.).

Date / Time

Pressing the DATE TIME soft-key in the Options menu will take you to a new screen that allows

you to specify and store the date and time for the meter’s internal clock. The date and time are

displayed on scan results.

6. Versions

Versions

Selecting Versions from the Main Menu list takes you to a screen that displays versions of

software that are loaded in the instrument. It also displays the hardware versions and serial

numbers of the XR-3 base unit and any connected module, as well as the active Field Guide and

Postal Code and Limits files.

XR-3 TS2 Module Operation Manual XR-3

Page 20 of 67

7. Azimuth / Elevation Lookup

The meter can look up the azimuth, elevation, and polarization offset for different satellites based

on the latitude and longitude that you specify. The azimuth is given in true north (Azimuth) and in

magnetic north (Magnetic) degrees. You should follow the Magnetic field value when using a

compass to point the satellite dish. You may change the selected satellite using the left and right

arrow keys.

In the United States, enter any zip code and this screen will look up the latitude and longitude for

that location and calculate the azimuth and elevation angles for the selected satellite.

The USA ZipCodes database in the meter holds all of the zip codes for the entire United States of

America, Puerto Rico, and the US Virgin Islands. There is also a database available for Canada

(Canadian Postal). Type in the zip code or postal code using the numeric keypad and press

ENTER.
