Trigger functions
Trigger
Trigger source
analyzer mode
free run, video, external, IF power
receiver mode
free run, video, external
Trigger offset
analyzer mode, span ≥ 10 Hz
31.25 ns to 30 s,
min. resolution = 31.25 ns
(or 1 % of offset)
analyzer mode, span = 0 Hz
(–sweep time) to 30 s,
min. resolution = 31.25 ns
(or 1 % of offset)
Max. deviation of trigger offset
analyzer mode
