These commands return results that are applicable to the entire 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 measurement suite overall pass/fail result, TX carrier power, ORFS Switching number of fetch points, up to eight comma-separated ORFS Switching (maximum) results, 30 kHz reference power, ORFS Modulation number of fetch points, and up to 22 ORFS Modulation (average) results.
The ORFS Switching number of fetch points, and the ORFS Modulation number of fetch points return a 1 when there are no points, to indicate that one value of 9.91 E+37 (NAN) will be returned.
Query Range:
Output RF Spectrum measurement suite integrity: See Measurement Integrity Indicator.
Output RF Spectrum measurement suite overall pass/fail result: 0 (pass), 1 (fail)
TX carrier power result: <nr3> in dBm and 9.91 E+37 (NAN)
ORFS Switching number of fetch points: 1 to 8
ORFS Switching (maximum) results:<nr3> in dBm and 9.91 E+37 (NAN)
30 kHz reference power result: <nr3> in dBm and 9.91 E+37 (NAN)
ORFS Modulation number of fetch points: 1 to 22
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 partial results for the entire ORFS measurement suite.
TestSet.WriteString("FETCh:ORFSpectrum?")
Queries the ORFS measurement suite integrity indicator and overall pass/fail result.
Query Range:
Output RF Spectrum measurement suite integrity: See Measurement Integrity Indicator.
Output RF Spectrum measurement suite overall pass/fail result: 0 (pass), 1 (fail)
Test Set Requirements: E6601A WCTS Program Version A.02 and above
Example:
' Query the ORFS measurement suite overall pass/fail result.
TestSet.WriteString("FETCh:ORFSpectrum:FAIL?")
Queries the intermediate total number of bursts measured. Refer to the following example return values:
If the number of ORFS Modulation averages completed is 20, the fast measurement state is set to On (see SETup:ORFSpectrum:MODulation:FAST[?]), and the number of Switching averages completed is 2, the value returned by this command is 10.
If the number of ORFS Modulation averages completed is 20, the fast measurement state is set to Off (see SETup:ORFSpectrum:MODulation:FAST[?]), and the number of Switching averages completed is 2, the value returned by this command is 20.
If the number of ORFS Modulation averages completed is 2, the fast measurement state is set to either On or Off (see SETup:ORFSpectrum:MODulation:FAST[?]), and the number of Switching averages completed is 20, the value returned by this command is 20 (since the fast measurement only applies to ORFS Modulation averages).
Query Range: 0 to 999
Test Set Requirements: E6601A WCTS Program Version A.02 and above
Example:
' Queries the intermediate total number of averages completed in the ORFS measurement suite.
TestSet.WriteString("FETCh:ORFSpectrum:ICOunt?")
Queries the integrity indicator for the last Power and Modulation Quality measurement suite completed. Zero indicates normal.
For non-zero integrity indicators, refer to Measurement Integrity Indicator.
Query Range: See Measurement Integrity Indicator.
Test Set Requirements: E6601A WCTS Program Version A.02 and above
Example:
' Query the integrity indicator for the last Output RF Spectrum measurement suite completed.
TestSet.WriteString("FETCh:ORFSpectrum:INTegrity?")
Returns the integrity indicator and the TX carrier power measurement result from the last ORFS measurement made.
Query Range:
Output RF Spectrum measurement suite integrity: See Measurement Integrity Indicator.
TX carrier power result: <nr3> and 9.91 E+37 (NAN)
Test Set Requirements: E6601A WCTS Program Version A.02 and above
Example:
' Query the TX carrier power from the last ORFS measurement.
TestSet.WriteString("FETCh:ORFSpectrum:TXPower?")
