Measurement Gates
A measurement gate allows measurements to be performed on particular sections of the
input signal. The gate is defined by a start time relative to the trigger event and a duration.
Signal samples acquired during the time interval specified by the gate are used for the
measurements in that gate. A system of up to four independent gates is provided.
Below is an example of a 4-gate setup to perform the following measurements
simultaneously:
Average power level of the pulse
Gate 1, average measurement
Average “off” power level ahead of the pulse
Gate 2, average measurement
Peak-to-average ratio
Gate 1, peak-to-average measurement
Pulse droop
Gate 3, average measurement, minus Gate 4, average
measurement
Gate 4
Gate 3
Gate 1
