GATED
TRIGGER
Statistic measurements on pulsed signals can be done using the GATED TRIGGER
softkey. An external frame trigger is required as a time (frame) reference.
The gate ranges define the part of the I/Q capture data taken into account for the
statistics calculation.
These ranges are defined relative to a reference point T=0. The gate interval is
repeated every period time until the end of the I/Q capture buffer.
The reference point T=0 is defined by the external trigger event and the instrument's
trigger offset.
GATED TRIGGER activates the gating for statistics functions. The trigger source is
changed to EXTERN if this function is switched on.
Remote command:
SWE:EGAT ON
[NO OF SAMPLES:
10000] Set the number of measurement samples to 10000.
[SINGLE MEAS] Start the measurement sequence. At the end the resulting
trace will display the CCDF for the measured 10000 sam-
ples.
The I/Q data capturing is repeated until the configured number of valid samples is
reached. If the active gate period is outside the I/Q capture buffer or the resulting
gate time is zero the measurement will not reach its end. In this case, the range
start and stop values have to be checked.
