again to return to measurement mode.
NOTE
In autonomous mode, the DRV3 always uses the ‘roof’ antennas since it
requires the DRV3 to be docked in order to operate in this mode.
3.2.3 Using Spectrum Mode
Spectrum mode is used for on-the-spot diagnosis by CPAT support team but is also available
for normal users. In this mode, the DRV3 can work as a simplified spectrum analyzer.
1. In the settings menu (page 1), select Spectrum.
2. Press the right arrow ( ) to set spectrum mode.
The possible values are:
• OFF: Disable spectrum mode
• AERO TAG: Frequency domain representation of AERO signal for AM tag analysis
• LTE TAG: Frequency domain representation of LTE signal for AM tag analysis
• AERO: Spectrum analyzer with a center frequency of the selected AERO frequency
and a span of 38KHz
• LTE: Spectrum analyzer with a center frequency of the selected LTE frequency and
a span of 38KHz
3. Press

4. Press
Esc
to activate spectrum mode. While in spectrum mode display, you can use
directional arrows to change center frequency. left and right arrow ( ) ( ) will respectively
decrease and increase current center frequency value by 1 KHz. Up and down arrow ( )
( ) will respectively decrease and increase current center frequency value by 10 KHz.
3.2.4 Setting up Proximity
The proximity setting is used to apply a correction factor to the distance between the
DRV3 and the probable leakage source in order to give a reading equivalent to a 10ft/3m
measurement. By selecting the distance, the DRV3 calculates the appropriate gain to apply
to the reading and then provides a normalized reading.
To change the Proximity:
