Description
Selects a trigger mode: free, line, video, or external.
The options are as follows:
Opt-
ion Mode Selected
EX-
T External mode. Connect an external trigger source to J5 EXT/GATE TRIG INPUT on the rear panel of the instrument.
The source must range from 0 to 5 V (TTL). The trigger occurs on the rising, positive edge of the signal (about 1.5 V).
FRE-
E Free-run mode. Sweep triggers occur as fast as the instrument will allow.
LIN-
E Line mode. Sweep triggers occur at intervals synchronized to the line frequency.
VID Video mode. Sweep triggers occur whenever the positively-sloped part of the input signal passes through the video
trigger level. This trigger level can be changed (refer to the VTL command), and a dashed line appears on the screen to
denote (approximately) the selected level. Video triggering is not available for resolution bandwidths
£100 Hz.
TV Allows TV triggering if Options 101 and 102, or Option 301 is installed. The functions of TM TV and TV TRIG are
similar. TM TV does not select the TV line number, set up the amplitude level, change the span, change the
bandwidth, or change the sweep time.
