FETCh:TDPChannel:FERRor[:BURSt[1]][:PARTial]?

Queries the Dedicated Physical Channel measurement suite integrity indicator, average frequency error in Hz, and average frequency error in ppm.

Query Range:

• Dedicated Physical Channel measurement suite integrity: See Measurement Integrity Indicator.

• Pass/Fail Result: 0 (pass), 1 (fail)

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

• Average Frequency Error (ppm): <nr3> in ppm and 9.91 E+37 (NAN)

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

Example:

' Query the integrity indicator, pass/fail result, average frequency error in Hz, and average frequency error in ppm.

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

FETCh:TDPChannel:FERRor[:BURSt[1]]:ALL?

Queries the Dedicated Physical Channel measurement suite integrity indicator, frequency error's overall pass fail result, worst error, minimum error, maximum error, average frequency error in Hz, average frequency error in ppm, and the frequency error standard deviation.

Query Range:

• Dedicated Physical Channel measurement suite integrity: See Measurement Integrity Indicator.

• Pass/Fail Result: 0 (pass), 1 (fail)

• Worst Case: <nr3> in Hz and 9.91 E+37 (NAN)

• Minimum: <nr3> in Hz and 9.91 E+37 (NAN)

• Maximum: <nr3> in Hz and 9.91 E+37 (NAN)

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

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

• Average Frequency Error (ppm): <nr3> in ppm and 9.91 E+37 (NAN)

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

Example:

' Query the integrity indicator, pass/fail result, worst case frequency error in Hz, minimum frequency error in Hz, maximum frequency error in Hz, average frequency error in Hz, and average frequency error in ppm.
