Incoming Inspection

The incoming inspection procedures are optional procedures that check the functionality of the instrument and require

no equipment other than a display. For a more robust inspection, see the performance veriﬁcation procedures in the

Speciﬁcations and Performance Veriﬁcation manual that is included on the User Documentation CD that was shipped

with your instrument.

BasicTurnOnandSelfTest

1. Connect an XGA monitor to the

instrument.

2. Connect the AC power cord to the rear of

the instrument and to a 100 to 240 VAC

source. There is no power switch on

your instrument: it will turn on as soon

as you apply power.

3. Look at the front panel immediately after

you apply power. All of the buttons, the

text over the three knobs, and the Fault

indicator should light up.

NOTE. After a couple of seconds, the lights

in the buttons and text will turn off. After

about 15 seconds, the fault light should turn

off and the Power On diagnostic page should

appear on the monitor.

4. Verify that the instrument passes all self

tests. Any failures will be shown in Red.

The results of the Power On diagnostics

are erased from the screen, but you

can view them by selecting CONFIG >

Utilities > View Diagnostic Log.

5. After the diagnostics are ﬁnished, the

instrument state will be restored. When

the progress indicator in the lower-right

part of the screen is ﬁnished, the

instrument has ﬁnished initi alizing.

Front Panel Test

1. Press FACTORY

to restore the factory

preset. Wait for the progress indicator to

show the process is complete.

2. Press FULL to m a ke the ac tive tile be

full screen.

3. Press HELP to

display the help screen.

4. Press all the

other buttons.

Each button s hould ﬂash as you press

it. Most buttons bring up related help

text. Some b

uttons, such as the presets,

bring up the same information. The

HELP button, the four arrow keys, and

the SEL but

ton do not bring up help text

because they traverse the help panes

and content.

5. Press the right arrow key until the Help

Contents pane in the upper-left corner is

highligh

ted.

6. Turn the G

ENERAL knob and verify that

the selector box moves up and down the

list.

7. Press HELP to exit help.

XGA and Extended Diagnostics Test

NOTE. Where th

e following procedure says to press an arrow key, you can use the general knob on the front panel,

if you prefer.

1. Press the CONFIG button to display the

conﬁguration menu.

2. Select Utilities and then press SEL.

3. Select CPU Color Palette Check

and verify

that 16 distinct colors are

displayed. This tests the XGA data path

from the CPU.

4. Use the down arrow key to navigate to

Run Advanced Diagnostics and then

press SEL.

5. When the dialog box appears, use the

right arrow key to highlight the Continue

box and then press SEL to run the test.

6. Verify that the XGA DAC is working by

looking at the White and Red ramps at

the top of the screen, and at the Green

and Blue ramps a t the bottom of the

screen. They should not have steps but

should show a smooth transition from

dark to light.

7. Verify that the frequencies shown are

within 10 kHz, and that rates shown are

within 0.1 μs,

of the nominal values listed

to the right.

8. Verify that the bus bit activity tests

(labeled Channel A:, Processor Video:,

and Composi

te Video:, and appearing at

the bottom of the screen) are as follows:

All three tests show both a red and a

green bar in each bit location.

The Processors Video test shows

8bitsfrom

the CP U, a space, then

Hsync, a space, Vsync, a space, and

then the blank line. It is normal for

the Vsync b

it to blink o ccasionally.

9. Press SEL

or cycle the power to reboot

the unit for normal operation.

QDR Clock = 25.174 MHz

VGA clock = 64.480 MHz

Audio PLL1 =

12.288 MHz

Audio PLL2 = 12.288 MHz

Hsync rate : Width = 0.9 μs

Vsync P W: Wi

dth = 62.5 μs

Fan Test

If the fault light in the lower left corner of the front panel is not on (Red), the fans are running. You should also be able to hear

them and feel air coming out the back of the instrument. At low temperatures, the fans will turn slowly and be very quiet.

Installation Va

riations

Installation Variations

See the Quick Start User Manual that was shipped with your instrument for basic installation instructions. Read the following

information for other installation situations and for remote communication instructions, an optional procedure that is suitable

for incoming inspection of this product.

Connecting Directly to a P C

The following procedure will help you connect y our instrument to a PC:

1. Connect the instrument to a PC through

an ethernet

hub, as shown. A standard

crossover cable can be substituted for

the hub.

2. Set up the instrument as described in

the follow

ing procedures (See page 6,

Connecting to a Network.), choosing

Manual IP mode to set the IP address

manually

. B e sure to set an address that

is compatible with the setting of your PC.

3. If you are using an SNMP setup, use the

SNMP setup procedure.

Waveform Rasterizers Technical Reference 5

Installation Va

riations

Connecting to a Network

The following topics cover conﬁguring the IP settings, so that you can use your instrument over a network, and conﬁguring

SNMP, which is required if you are using commands to control the instrument.

Connection and IP Settings

To allow net

work access to the instrument, y ou need to set the IP address. Network addresses can be assigned either

automatically or manually. If your network does not use DHCP, you will have to m anually enter the address for the instrument.

To get an address, talk to your LAN administrator.

To connect your instrument to a network and

access it wi

th a remote PC, do the following:

NOTE. To connect directly between your PC

and the instrument, see Connecting Directly

to a PC.

1. Press CONFIG to display the

Conﬁguration menu.

2. Select Network Settings > Web Enable.

Press SEL to select On.

3. Set the IP Conﬁg Mode to Manual or

DHCP, depending on your network setup.

4. If you cannot use DHCP, set the subnet

mask and gatew

ay address network

parameters in this menu; see your

LAN administrator for required values.

(Besuretous

e compatible addresses

between the PC and the instrument.)

You can also set the instrument name

and view the

MAC Address.

5. If the passw

ord is set, note it. You will

be prompted for it when you connect to

the instrument.

NOTE. For h

elp w ith entering or changing

the password, select Web Password, and

press the HELP button.

6. Press CONFIG to close the Conﬁguration

menu.

Waveform Rasterizers Technical Reference 7

Installation Va

riations

SNMP Setup

If you intend to use SNMP commands to control the instrum ent (SNMP control is primarily intended for access through

automation systems), you need to set up SNMP parameters.

NOTE. The WFM, WVR, and AMM Series Waveform Monitors wfm_mon.mib and the WVR7120.mib can be downloaded

from the instrument Web page.

The procedure to set SNMP settings is similar to that shown on page 2 for IP settings; the parameters that can be set follow:

SNMP Enable This entry in the Network Settings portion of the Conﬁguration m enu allows you to

turn on or off the remote access through SNMP.

SNMP Trap Enable This menu entry allows you to turn on or off the traps that are sent out through SNMP.

SNMP Trap Address This menu entry allows you to set IP addresses to w hich SNMP traps are sent through

SNMP. Traps can be sent to up to four addresses when error conditions are detected.

NOTE. A value of all zeroes for the address will disable that trap output.

Private Community S tring This menu entry allows yo u to set the Private Community string. This string is

effectively a password. Without this string, SNMP commands cannot change values

in the instrument.

NOTE. The P rivate S tring is necessary for SNMP access to write changes into

the instrument.

Public Community String This menu entry allows you to set the Public Community string. This string is

effectively a password. Without this string, SNMP commands cannot read values

from the instrument.

NOTE. The Public String is necessary for SNMP access to read values from the

instrument.

Remote Communication

The f

ollowing topics cover remote c ommunications that occur:

Over

an Ethernet network through a Web browser

Ove

r an Ethernet network through a Java applet

Ove

r a cable using the optional remote front panel
