7.3.6.2 Multi-Burst Power Measurement
The multi-burst power measurement function is suitable for measuring the power of
a sequence of pulses with the following characteristics:
•
•
The function requires one trigger event per pulse. This means that if the video trig-
ger or the IF power trigger is used, the levels of all pulses must be above the trigger
threshold.
The function is, therefore, particularly suitable for re-measuring DUTs already
adjusted and whose output power is within the specified range. The measurement is
optimized for minimum overhead relative to the actual measurement time.
Operating Manual 1302.6163.12 - 03
The pulses occur at variable time intervals.
The levels of all pulses of the sequence are reliably above the trigger threshold,
or an external trigger signal is used.
