FETCh:RFCHannel:FERRor?

Last Updated: August 29, 2007

These commands return results for the Frequency Error measurement in the RF Channel (RFCH) measurement suite.

• FETCh:RFCHannel:FERRor[:PARTial]?

• FETCh:RFCHannel:FERRor:ALL?

FETCh:RFCHannel:FERRor[:PARTial]?

Queries the integrity indicator and the average frequency error.

If the multi-measurement state is on, the results represent the average of a number of frequency error measurements. Multi-measurement state, by default, is off. To set up multi-measurements, see SETup:RFCHannel:COUNt:NUMBer[?].  

Query Range:

• RF Channel measurement suite integrity: See Measurement Integrity Indicator.

• Frequency error (average): <nr3> in Hz and 9.91 E+37 (NAN)

Test Set Requirements: E6601A WCTS Program Version A.05 and above

Example:

' Query the integrity indicator and the average frequency error.

TestSet.WriteString("FETCh:RFCHannel:FERRor?")

FETCh:RFCHannel:FERRor:ALL?

Queries the integrity indicator, minimum, maximum, average, and standard deviation of frequency error multi-measurement results. To set the number of measurements used to gather statistics, use the command SETup:RFCHannel:COUNt:NUMBer[?].  

Query Range:

• RF Channel measurement suite integrity: See Measurement Integrity Indicator.

• Frequency error (minimum): <nr3> in Hz and 9.91 E+37 (NAN)

• Frequency error (maximum): <nr3> in Hz and 9.91 E+37 (NAN)

• Frequency error (average): <nr3> in Hz and 9.91 E+37 (NAN)

• Frequency error (standard deviation): <nr3> in Hz and 9.91 E+37 (NAN)

Test Set Requirements: E6601A WCTS Program Version A.05 and above

Example:

' Query the integrity indicator, minimum, maximum, average, and standard deviation
' of frequency error multi-measurement results.

TestSet.WriteString("FETCh:RFCHannel:FERRor:ALL?")
