Network Analyzers using S2VNA software

Turns ON/OFF miss detector of the external trigger. An external trigger is used to start sweeps of the FIFO buffer function. When a trigger miss is detected, a dummy sweep is inserted into the FIFO buffer. The data from the previous sweep is copied into the dummy sweep. The number and list of skipped sweeps are available using the commands SYST:FIFO:MISS:SWE:COUN? and SYST:FIFO:MISS:SWE:LIST?.

Limitation: The function cannot detect missing the last trigger of a sequence. To overcome the limitation, two methods can be used:

•Use the number of triggers, one more than required.

•Compare the number of sweeps read with the number of triggers submitted. The number of sweeps read will be one less than the number of triggers submitted if the last trigger is missed.
