Trigger Commands
Trigger commands control all aspects of oscilloscope triggering. Table 2--25 lists
these commands.
There are two triggers, A and B. Where appropriate, the command set has
parallel constructions for each trigger.
You can set the A or B triggers to edge mode. Edge triggering lets you display a
waveform at or near the point where the signal passes through a voltage level of
your choosing.
The advanced trigger commands are divided into two groups (logic and pulse) in
the following tables, but are combined and listed in alphabetical order in the
command syntax pages.
This table also includes the TDS3VID Extended Video application module
remote command syntax.
