Chapter 4, Description of Fields
Fields
Carrier
This field is displayed when Carrier is selected from the list of choices available
when the unnamed field displaying one of the following choices is displayed:
• phase error measurement
• carrier feedthrough measurement
GPIB Example
“DISP CTXT;MEASure:CDManalyzer:CARrier:FEEDthrough?“
queries the carrier feedthrough measurement result.
Operating Considerations
These measurements, along with rho, frequency error, amplitude error, and time
offset are made by DSP analysis techniques. The
Meas Cntl field triggers these
measurements.

Carrier Ref
Use the carrier reference field to indicate whether the carrier (Tune Freq) being
measured should be unmodulated or modulated when making the ACP reference
measurement. (For more information, refer to
"How the Test Set Measures
Adjacent Channel Power (ACP)" on page 83
.)
Operating Considerations
• FM transmitters can be measured with the carrier modulated or unmodulated.
• For AM transmitters, the carrier must be measured while unmodulated. AFGen1 and
the AUDIO OUT port must be used as the modulation source whenever Unmod is
selected.
