10) QMA CONNECTOR (RF Input) - for connecting the included REI antennas or other RF antennas.
ANDRE Packages
The ANDRE is available in three packages (Basic, Advanced, and Deluxe) with varying probes, antennas, and
accessories. Below is a chart showing which probes, antennas, and accessories are included in each package (note
that this is subject to change). Additional information can be found in the Probes, Antennas, and Accessories
section on the following pages.
10
Probes, Antennas, and Accessories
Whip / Dipole Antenna (30MHz - 6 GHz)
The Whip / Dipole is a general-purpose, omnidirectional, near-field probe used for locating RF transmitters up to 6
GHz.
Concealed Antenna (750 MHz - 6 GHz)
The Concealed Antenna is omnidirectional and is used for covert detection of devices. When the concealed antenna
is connected, the ANDRE will automatically switch to Covert Mode. This mode could be used to conduct a covert
search by connecting the concealed antenna and then hiding the unit in, for example, a jacket pocket while walking
around the room and relying on the haptic feedback for alerts. Covert mode automatically disables any alerting
features. It turns the speaker off, enables haptic feedback mode, and shuts off the display and the power LED.
11
Locator Probe (20 MHz - 6 GHz)
The Locator Probe is an omnidirectional probe and is attenuated for use in high RF environments and for locating an
RF signal within a few inches.
VLF Loop Antenna (10 kHz - 30 MHz)
The VLF Loop Antenna is an omnidirectional antenna used for locating low-frequency signals below 30 MHz.
Acoustic Leakage Detector (ALD)
With the Acoustic Leakage Detector, the operator can determine the vulnerability of acoustic leakage by placing the
probe against structural objects such as walls or windows. The Acoustic Leakage Detector connects to the Audio
Input on the ANDRE.
12
Audio Transformer (300 Hz – 20 kHz)
The Audio Transformer is a balanced audio coupler to provide electrical
isolation for audio testing. A 3.5 mm Stereo to 3.5 mm Stereo cable is
included with the ANDRE to connect the audio transformer to the
ANDRE. Two push buttons provide positive and negative bias voltage to
the two banana jacks on the audio transformer. The control knob on the
audio transformer adjusts the level of the applied bias voltage from 0 to
22 volts. An included set of banana-jack test leads with bed-of-nail
alligator clips allow the audio transformer to be used on 66 blocks or
other wires.
Carrier Current Probe (100 kHz to 60 MHz)
The Carrier Current Probe can be used to test for carrier current signals on any
pair of conductors less than 250 volts. Before testing an unidentified pair of
power conductors, a voltmeter should be used to measure the voltage across
the conductors. If this voltage exceeds 250 volts, do not test with the Carrier
Current Probe. Two power plugs are included for connection to US style or Euro
style outlets. The included alligator clip cable assembly should only be used on
50V or less. Measurements can be made with three different pair
configurations using the switch on the front of the carrier current probe:
Hot/Neutral, Neutral/Ground, and Hot/Ground.
Due to power line noise and the broad frequency range that ANDRE searches,
every outlet in an area should be inspected.
Note: the frequency counter is disabled when using the Carrier Current Probe
and the operator should rely on the detected signal strength when using the
carrier current probe. No frequency will be displayed while using the Carrier
Current Probe, nor will any signals be added to the signal list.
13
Log Periodic Antenna (500 MHz – 6 GHz)
The directional antenna is a log periodic antenna that can be used for improved detection in the 500 MHz to 6GHz
range.
Directional Antenna (70 MHz- 500 MHz)
This flag-shaped antenna provides directional coverage for lower-frequency signal detection. It is a powered probe
and must be used with one of the powered connector cables (see page 29).
14
Down Converter Directional Antenna (500 MHz – 12 GHz)
The Down Converter Antenna is a directional antenna that operates in two user-selectable bands (see page 30):
Band 1: 500 MHz – 6 GHz
Band 2: 6 GHz – 12 GHZ
When using Band 2, the Down Converter Antenna converts signals occurring above the standard 6 GHz threshold so
they can be detected and displayed on the ANDRE. For details on operation, (see page 30)
The down converter antenna is a powered probe and must be used with one of the powered connector cables (see
page 29).
Ultrasonic Probe (15 kHz – 80 kHz)
The ultrasonic probe detects sound waves operating above the upper limit of human hearing capabilities. The
ultrasonic probe connects to the ANDRE with the provided audio patch cable. For details on Ultrasonic probe
operation (see page 30).
15
Nitecore Dual Bay Battery Charger
The Dual-Slot Battery Charger allows the user to externally charge two of the ANDRE Lithium-Ion batteries for high-
speed charging.
Note: The Dual Bay Battery Charger is available with the ANDRE Advanced and Deluxe models. It can also be
purchased separately by contacting REI or an Authorized REI reseller.
1) Connect the USB micro end of the cable to the port on top of the charger. Connect the USB-A end to an AC
power adapter, a PC, or another standard USB output port.
2) Insert the batteries to be charged being sure to observe the polarity markings on the charger.
3) After battery installation, the charger will run a quick battery test before charging. If a problem is detected
(for example, the batteries are installed backward), charging will stop, and "EE" will be displayed on the LCD
to notify the user.
4) Battery charge progress and completion are indicated on the screen.
Operation
The ANDRE has been designed for quick and easy deployment. Depending on the user's application some
adjustments to the default setting may need to be made.
The ANDRE is a broadband RF detector and is used to locate transmitters by monitoring the RF signal strength.
When searching for unknown transmitters, it is advised to remove or disable any known transmitters from the
target sweep area (i.e., unplug, turn off, or remove any wireless transmitting devices including Wi-Fi and Bluetooth
devices, laptops/PCs, mobile phones, wireless transmitting devices, etc.), as any transmitting devices can affect the
RF noise floor and hinder detection of unknown transmitters.
Also, the process of connecting a probe or changing the settings on the ANDRE may cause inaccurate signal levels or
other abnormal behavior and may result in the addition of unwanted, invalid signals to the signal list. REI
recommends the following process for using the ANDRE in a sweep:
1) Configure the ANDRE for use (set attenuation/gain, adjust trigger level, set chart audio, set haptic style,
etc.).
2) Connect a probe and confirm correct input source.
3) Clear the signal list (see page 22) and data log (if enabled) (see page 31).
4) Begin sweep.
16
Battery Usage
Lithium-Ion rechargeable batteries have been included with the unit. The ANDRE will operate with just one charged
battery inserted; however, use two batteries for the longest run time.
To insert or switch out a new battery:
1) Locate the battery door on the back of the unit.
2) Using both thumbs, slide the battery door open in the direction of the arrows engraved in the plastic. The
battery door will slide open just a couple of millimeters but can then be flipped up.
3) Labels inside the battery compartment indicate the correct polarity of the batteries.
4) After inserting the batteries, close the battery door by flipping it back down and sliding the battery door
back in the opposite direction of the arrows.
17
The ANDRE has a built-in battery charger. To charge the battery in the unit:
1) Locate the included AC adapter and USB cable. Connect the USB cable to the AC adapter.
2) With the battery already inserted in the unit, connect the AC adapter to an AC source and the USB cable
end to the USB Port on the ANDRE. The battery will begin charging. Charging is automatic; it will stop
when the battery is fully charged. While the battery is charging, the power LED will flash green; the
flash rate will be proportional to the charge level.
Note: To keep the batteries in good working condition, they should be removed from the ANDRE for long-term
storage of 90 days or more. Even when powered off, the operating system of the ANDRE continues to use a low
stand-by current that in some cases could cause a deep discharge and possible damage to the battery, preventing a
normal recharge. To extend battery life it is recommended that the batteries are charged every three months when
unused for long periods.
Audio Transformer Batteries
The audio transformer, an accessory probe included with the ANDRE Advanced and Deluxe models, requires two
A23C batteries, which are customer replaceable.
To replace the audio transformer batteries:
1) Remove the two screws from the back of the audio transformer
using a Phillips head screwdriver.
2) Locate the two A23C batteries and replace them, being careful to
observe the polarity marked on the unit.
18
Display Screens
Display Screen Layout
Although several different screens are available for the ANDRE, they all use a common layout.
Screenshot — Tapping the camera icon in the status bar will take a screenshot and save it to the unit in .png format
using an automatically generated file name based on a header specified by the user (see page 38). The captured
screenshot can be viewed on the ANDRE using the Image Viewer (see page 39) or the file can be accessed directly
by connecting the ANDRE to a PC (see page 27).
Mute/Volume Control — Tapping this icon will bring up the mute and volume controls. Tapping the mute control
on the left will toggle the audio. Dragging the adjustment control on the right will increase or decrease the volume.
The controls will disappear after a few seconds if there is no activity.
Status Icons — This area of each screen contains status icons indicating the current condition of the ANDRE unit.
Battery status and current time are displayed here.
Input Select - The input select button allows the user to manually select the signal source - either RF Input (QMA
connector), Audio Input, or IR/Visible Light Sensor. If an REI probe or antenna is connected to the currently selected
input source, this button will also display the name of the probe and the frequency range.
Detected Frequency — The ANDRE contains an internal frequency counter. This frequency counter detects ambient
signals based on their detected signal strength (a function of both the signal’s power and its proximity to the
ANDRE). The ANDRE will lock on to the strongest signal and the estimated frequency will be displayed here. If no
signal is strong enough to be detected by the ANDRE, no frequency will be displayed and dashed lines will indicate
this. This function is affected by the frequency gate setting. (see page 33).
Note: Lower frequencies (below 100 MHz) may not be as accurate or reliable as frequencies above 100 MHz.
Weaker target signals may also be less accurate, so it is a good practice to rely on the detected signal strength to
locate the source of the RF energy (get close to the target) and then use the Detected Frequency information to
evaluate the energy.
19
Gain Control - This button allows the user to change the attenuation or gain level of the ANDRE. Four levels are
available: +15 dB, 0 dB, -10 dB, -20 dB. Gain control is not available when the selected input source is the IR/Visible
Light sensor because gain is forced to -20 dB in this mode.
Main Area - The content of this area will vary depending on which screen is currently selected.
Navigational/Function Icons - The icons in this area are for navigating to the various available screens, accessing
setup controls, or performing a reset.
RESET - The operation that occurs when the RESET Button is pressed will vary
depending on what screen the user is on when the reset button is pressed. The
dialog screen that appears when the RESET button is pressed will provide
information on what items will be reset.
SETUP MENU - The ANDRE unit can be configured for multiple situations and use
cases. Most settings changes are handled through the SETUP MENU.
CHART SCREEN - The chart screen provides a time-based history of the ambient RF
Level and is the main operating mode of the ANDRE, where the ANDRE is used as a
near-field detector with the user in motion walking around the target area.
SIGNAL LIST SCREEN - The signal list screen provides an automatically generated list
of signals that have crossed the trigger level established by the user on the chart
screen.
AUDIO SCREEN - The audio screen allows the user to listen to audio from the audio
input, listen to live demodulated signals from RF sources, record live audio input or
demodulated audio, or playback previously recorded audio files.
20
Chart Screen (Search)
By default, the Chart Screen is the initial screen shown after the ANDRE is powered on. The chart screen can also be
selected, if it is not the currently displayed screen, by pressing the "Chart" icon that appears at the bottom of each
screen. The chart screen provides a time-based history of the ambient RF Level and is the main operating mode of
the ANDRE, where the ANDRE is used as a near field detector with the user in motion walking around the target
area.
Zoom — The chart is normally displayed with a vertical range of 90 dB. Pressing Zoom displays a 30 dB
segment of this full range. The 30 dB range displayed will be automatically selected based on the ambient signal
level at the time that the zoom button is pressed. The reduced scale will enable the user to more easily see small
changes in signal level. Press the Zoom button again to return to the full vertical scale chart.
Trigger Level — If the RF level goes above the adjustable trigger level the ANDRE will alert the user in various ways
depending on the current settings. The user is visually alerted when the color of the RF Level History graph changes
from green to red. Haptic alerts are available (see page 35) as well as audio alerts (see page 34). The trigger level
can be adjusted manually by pressing on the trigger level marker and dragging up or down. It can be adjusted by
tapping within the top two-thirds of the chart area, as described below. It can also be adjusted automatically (see
pg. 33).
Decaying Peak Level — The red line on the bar graph is a decaying peak level indicator for the ambient RF level.
Ambient RF Level — the bar graph on the chart screen displays the current instantaneous ambient RF level.
Trigger Level Set — Tapping anywhere within the top two-thirds of the chart area will adjust the trigger level to the
current ambient RF level
RF Level History — This area provides a visual history of recent RF levels. The graph is normally in green, but
changes to red anytime that the RF level crosses the set trigger level.
Note: The RF Level history is red if the RF level is above the trigger level or if it is increasing above the trigger level. It
is green if the RF level is below the trigger level or decreasing below the trigger level. So there will be portions of
