Chapter 4, Description of Fields

Fields

Freq (Channel Information)

Selecting this field displays the TESTS (Channel Information) screen.

Screens Where Field is Present

TESTS (Main Menu)

Freq Error (CDMA)

This field is displayed when Freq Error is selected from the list of choices available when the unnamed field displaying one of the following choices is displayed:

frequency error

amplitude error

time offset measurement

GPIB Example

“DISP CTXT;CDMA:RHO:MEAS:FERR ‘Freq Error’”

selects frequency error from the list of choices.

“DISP CTXT;MEASure:CDManalyzer:FREQ:ERRor?“

queries the CDMA frequency error measurement result.

Operating Considerations

These measurements, along with rho, phase error, and carrier feedthrough are made by DSP analysis techniques. The Meas Cntl field controls these measurements.

Frequency error is referred to as ΔF.
