Sets/queries the time offsets (for the specified burst of the multislot configuration) for the Power versus Time power measurement, (not the mask measurement).
All 12 time offsets are set to on by default. If less than 12 values are sent with this command, the remaining offsets are turned off. These values are referenced to the occurrence of bit 0 in a normal burst.
Burst 1 is assumed if you do not use the optional [:BURSt([1]|2)] part of the command.
The units (S|MS|US|NS) are optional, if no units are specified then units default to S.
Setting Range: 0 to 12 comma-separated values ranging from: -50 μs to 593 μs
Query Range: 1 to 12 comma-separated values ranging from: -50 μs to 593 μs and 9.91E+37 (NAN) if no offsets are specified
Resolution: 1 ns
*RST Setting: Time offsets 1 through 12 are on and set to these values:
time offset 1 = Burst 1: -28 μs, Burst 2: 0 μs
time offset 2 = Burst 1: -18 μs, Burst 2: 0 μs
time offset 3 = Burst 1: -10 μs, Burst 2: 0 μs

Test Set Requirements: E6601A WCTS Program Version A.01 and above
Example:
' Configure the first six time offset points and turn the remaining six off for burst 2.
' Using the query form of this command would return six time offset values.
TestSet.WriteString("SETup:PMODulation:PVTime:BURSt2:TIME 0US, 0US, 0US, 0US, 321.2.0US, 331.2US")
Queries the number of the specified burst's measurement offset points that are turned on during a Power versus Time measurement.
This command is useful for determining how many time values are returned in a comma-separated list when the SETup:PMODulation:PVTime[:BURSt([1]|2)]:TIME[:OFFSet][?] query is sent, and how many power values are returned when the FETCh:PMODulation:PVTime[:BURSt([1]|2)]:POWer? command is sent.

*RST Setting: 12
Test Set Requirements: E6601A WCTS Program Version A.01 and above
Example:
' Query the number of measurement offset points for burst 1.
TestSet.WriteString("SETup:PMODulation:PVTime:BURSt1:TIME:POINts?")
Sets the specified custom mask values to the current ETSI mask values. This command is the remote equivalent of selecting Copy Current ETSI to Custom on the PvT Masks tab, in the Power and Modulation Quality Setup window.
Test Set Requirements: E6601A WCTS Program Version A.01 and above; A.04 added CUSTom1 (previously it was CUSTom) and CUSTom2
Sets/queries the lower limits for the specified custom mask to be used with the Power versus Time measurement. This command allows you to define two custom masks by specifying CUSTom1 or CUSTom2.
A total of 32 reference points are available to you when defining a custom mask. All custom masks have a step profile rather than a linearly interpolated profile. Each custom mask has a fixed starting point which is located -50 μs relative to the middle of symbol zero (that is, T0). All mask reference points that you specify are end points of one section of the custom mask.
If you use this command without specifying any parameters, the previously defined mask is cleared.
