These commands return results for the ORFS Modulation measurement in the Output Rf Spectrum (ORFS) measurement suite.
For more information on the conventions used in the programming examples click here.
Queries the ORFS measurement suite integrity, ORFS Modulation pass/fail result, 30 kHz reference power, ORFS Modulation number of fetch points, and up to 22 ORFS Modulation (average) results.
The ORFS Modulation number of fetch points returns a 1 when there are no points, to indicate that one value of 9.91 E+37 (NAN) will be returned.
The SETup:ORFSpectrum:MODulation:FREQuency[:OFFSet][?] command sets up the number of ORFS Modulation offsets that are turned on and their frequency values. The SETup:ORFSpectrum:MODulation:FREQuency:POINts? command queries the number of ORFS Modulation points that are turned on, indicating the number of ORFS Modulation (average) values to expect when you FETCh ORFS Modulation results.
Query Range:
Output RF spectrum measurement suite integrity: See Measurement Integrity Indicator.
ORFS Modulation pass/fail result: 0 (pass), 1 (fail)
30 kHz reference power result: <nr3> in dBm and 9.91 E+37 (NAN)
ORFS Modulation number of fetch points: <nr1>
ORFS Modulation (average) results: <nr3> in dB and 9.91 E+37 (NAN)
Test Set Requirements: E6601A WCTS Program Version A.02 and above
Example:
' Query the ORFS measurement suite integrity, ORFS Modulation pass/fail result,
' 30 kHz reference power, ORFS Modulation number of fetch points,
' and up to 22 ORFS Modulation (average) results.

Queries the ORFS measurement suite integrity and the ORFS Modulation pass/fail result.
Query Range:
Output RF spectrum measurement suite integrity: See Measurement Integrity Indicator.

TestSet.WriteString("FETCh:ORFSpectrum:MODulation:FAIL?")
Queries the ORFS measurement suite integrity, ORFS Modulation pass/fail result, 30 kHz reference power, ORFS Modulation number of fetch points, and the standard deviation of the power level for up to 22 frequency offsets.
The ORFS Modulation number of fetch points returns a 1 when there are no points, to indicate that one value of 9.91 E+37 (NAN) will be returned.
