Programming Reference
The commands of the TRIGger subsystem allow you to set ah the trigger
conditions necessary for generating a trigger. There are two trigger
modes: Edge and Immediate. If a command is valid for the chosen trigger
mode, then that setting wiII be accepted by the oscilloscope. However, if
the command is not valid for the trigger mode, an error wih be generated.
None of the commands of this subsystem are used in conjunction with
Immediate trigger mode. See Figure 23-l for the TRIGger subsystem
syntax diagram.
In the Edge trigger mode, the oscilloscope triggers on an edge of a
waveform, specified by the SOURce, LEVel, and SLOPe commands. If a
source is not specified, then the current source is assumed.
In the Immediate trigger mode, the oscilloscope wiII trigger by itself when
the arming requirements are met.
