Trigger
Trigger Level
Sets the trigger level to be used for the RF Burst trigger. This same level is used in the RF Burst trigger source in
the Trigger menu. See section “Absolute Trigger Level” on page 1360for information on this key and the SCPI
command.
Trig Slope
Controls the RF Burst trigger polarity. It is set positive to trigger on a rising edge and negative to trigger on a
falling edge. This same value is used in the RF Burst trigger source in the Trigger menu. See section “Trigger
Slope ” on page 1363 for information on this key and the SCPI command
Trig Delay
This setting delays the measurement timing relative to the Periodic Timer.
Sync Holdoff
Sync Holdoff specifies the duration that the sync source signal must be kept false before the transition to
true to be recognized as the sync timing. The periodic timer phase is aligned when the sync source signal
becomes true, after the Holdoff time is satisfied.
A holdoff of 2 ms will work with most WiMAX signals, but there may be cases where the burst off
duration is less than 1 ms and this value will need to be changed.
Couplings: Same as RF Burst trigger source.
