Trigger operations
The following paragraphs discuss front panel triggering, the programmable trigger delay, the
reading hold feature, and external triggering.
Trigger model
The flowchart in Figure 3-2 summarizes triggering as viewed from the front panel. It is called
a trigger model because it is modeled after the SCPI commands used to control triggering. Note
that for stepping and scanning, the trigger model has additional control blocks. These are
described later in this section.
Idle
The instrument is considered to be in the idle state whenever it is not performing any
measurements or scanning functions. From the front panel, the unit is considered idle at the end
of a step or scan operation when the reading for the last channel remains displayed. To restore
triggers, use the SHIFT-HALT keys.
Once the Model 2010 is taken out of idle, operation proceeds through the flowchart.
Control source and event detection
The control source holds up operation until the programmed event occurs and is detected. The
control sources are described as follows:
• Immediate — With this control source, event detection is immediately satisfied allowing
operation to continue.
• External — Event detection is satisfied for any of the following three conditions:
• An input trigger via the Trigger Link line EXT TRIG is received.
• A bus trigger (GET or *TRG) is received.
• The front panel TRIG key is pressed. (The Model 2010 must be taken out of remote
before it will respond to the TRIG key. Use the LOCAL key or send LOCAL 716 over
the bus.)
