Power Meter Field Definitions
Power
Indicates the RF Power reading. The broadband power measurement function is only available
when the T/R Connector
is selected for the RF Input.
Units
Sets the unit of measurement for the RF Power reading.
Inband/Broadband
This button toggles between Inband and Broadband power measurements. The Inband Power
measurement function is available when the ANT (Antenna) Connector
or T/R Connector is
selected for RF Input. The Broadband/Inband button is only active when the T/R Connector
is
selected.
Calibrate
When pressed, the Test Set compensates measurement variations resulting from temperature
changes. This function is the same as running the UTILS mode procedure (refer to Chapter 3,
section titled User Calibration Tile
). This button is only available when Inband Power
measurements are selected.
Zero
When pressed, the Test Set zeroes out any internal cable loss. This button is only available
when Broadband Power measurements are selected.
Modulation Analyzer Field Definitions
Demod Freq
Displays the averaged frequency of the modulating signal.
FM/AM
Displays the measured Deviation or Modulation Depth of the signal.
Distn (Distortion)/SINAD
Displays the measured noise level on the demodulated signal, using the audio signal applied to
the unit under test as the reference. The desired noise measurement (Distortion or SINAD) is
selected from the [Noise Meters] Soft Key sub-menu.
Filter
Selects a measurement filter to include in the measurement path.
Demod Out sets the FCTN GEN/DEMOD Connector
as the Demodulation Output.
AF Out sets the FCTN GEN/DEMOD Connector
as the AF Generator Output.
Changing configuration to Demod Out while still connected to the MIC/AF Input of a radio
under test may create a feedback loop.
Loudspeaker
Selects the source and routing of the signal applied to the loudspeaker within the Test Set.
