These commands are only applicable with a PAvT license.
These commands setup Phase and Amplitude versus Time measurements.

Sets queries an array of up to 512 pairs of values representing the interval centers and the interval widths. The units (S|MS|US|NS) are optional, if no units are specified then units default to S.
You must ensure that:
interval center + (interval width/2) ≤ 512 ms
interval center - (interval width/2) ≥ 0
Setting Range:
Step Center: 0.5 ms to 511.5 ms
Step Width: 100 μs to 512 ms
Query Range:
Step Center: 0.5 ms to 511.5 ms
Step Width: 100 μs to 512 ms
Resolution:
Step Center: 10 μs
Step Width: 10 μs
*RST Setting:
Step Center: 1 ms
Step Width: 1 ms
Test Set Requirements: E6601A WCTS Program Version A.03 and above
Example:
' Set the interval widths and centers.
TestSet.WriteString("SETup:PAVTime:STEP 10MS,20MS,30MS,20MS,50MS,20MS,70MS,20MS")
Queries the total number of steps of the wireless device's discrete waveform calibration signal the test set is to measure. This is the number of pairs you set up using SETup:PAVTime:STEP[:POINts][?]. This may not be the same number as is actually measured. To determine the number of points measured use FETCh:PAVTime:STEP:COUNt?.
Setting Range: 1 to 512
Query Range: 1 to 512
Resolution: 1
*RST Setting: 1
Test Set Requirements: E6601A WCTS Program Version A.03 and above
Example:
' Query the step count.
TestSet.WriteString("SETup:PAVTime:STEP:COUNT?")
The setting form of this command performs two functions: (1) sets the measurement timeout value in seconds for Phase and Amplitude versus Time measurements (see SETup:PAVTime:TIMeout:TIME[?]) and (2) sets the measurement timeout state to on (see SETup:PAVTime:TIMeout:STATe[?]).
Setting Range: 0.1 to 999.9 s
Query Range: 0.1 to 999.9 s
Resolution: 0.01 s
*RST Setting: 10 s
Test Set Requirements: E6601A WCTS Program Version A.03 and above
Example:
' Set the measurement timeout to 20 seconds.
TestSet.WriteString("SETup:PAVTime:TIMeout 20")
Sets/queries the measurement timeout state for Phase and Amplitude versus Time measurements.
The measurement timeout state can also be set to on using the SETup:PAVTime:TIMeout[:STIMe][?] command.
Setting Range: 0 | OFF | 1 | ON
Query Range: 0 | 1
*RST Setting: 0 | OFF
Test Set Requirements: E6601A WCTS Program Version A.03 and above
Example:
' Turn the measurement timeout state to on.
TestSet.WriteString("SETup:PAVTime:TIMeout:STATe ON")
Sets/queries the measurement timeout value in seconds for Phase and Amplitude versus Time measurements. The units (S|MS|US|NS) are optional, if no units are specified then units default to S.
The measurement timeout value can also be set using the SETup:PAVTime:TIMeout[:STIMe][?] command.
Setting Range: 0.1 to 999.9 s
Query Range: 0.1 to 999.9 s
Resolution: 0.01 s
*RST Setting: 10 s
Test Set Requirements: E6601A WCTS Program Version A.03 and above
Example:
' Set the measurement timeout to 10 seconds.
TestSet.WriteString("SETup:PAVTime:TIMeout:TIMe 10")
Sets/queries the Phase and Amplitude versus Time measurement trigger delay in seconds. The units (S|MS|US|NS) are optional, if no units are specified then units default to S. See Triggering of Measurements.
Setting Range: 0 ms to 10 ms
Query Range: 0 ms to 10 ms
Resolution: 0.1 μs
*RST Setting: 0 ms
Test Set Requirements: E6601A WCTS Program Version A.03 and above
Example:
' Set the trigger delay time to 0.005 s.
TestSet.WriteString("SETup:PAVTime:TRIGger:DELay .005")
Sets/queries the trigger source for Phase and Amplitude versus Time measurements. See Triggering of Measurements.
Setting Range: ARB | EXTernal | IMMediate | RISE
Query Range: ARB | EXT | IMM | RISE
*RST Setting: RISE
Test Set Requirements: E6601A WCTS Program Version A.03 and above; A.04 added ARB
Example:
' Set the trigger source to Rise.
TestSet.WriteString("SETup:PAVTime:TRIGger:SOURce RISE")
Sets/queries the trigger threshold for the Phase and Amplitude versus Time measurement. See Triggering of Measurements.
Setting Range: -100 to 10 dB
Query Range: -100 to 10 dB
Resolution: 0.01 dB
*RST Setting: -10 dB
Test Set Requirements: E6601A WCTS Program Version A.03 and above
Example:
' Sets the trigger threshold for the Phase and Amplitude versus Time measurement to 0 dBm.
TestSet.WriteString("SETup:PAVTime:TRIGger:THReshold 0")
