Trigger System
Trigger System
B2900 supports the ARM-TRIGGER model described in 1999 SCPI Command
Reference . Operation summary of this trigger model is described below. Also see
Figure 6-8 .
The trigger system can be initiated by pressing the Trigger key on the front panel.
For the trigger setup parameters, see “Trigger parameters” on page 4-17 and
“Trigger Configuration dialog box” on page 4-38 .
1. Moves to the ARM layer if the trigger system was initiated.
2. Waits for the ARM event which is a signal from the ARM trigger source.
3. Moves to the TRIGGER layer if the ARM event was detected and the ARM
delay time elapsed.
4. Waits for the TRIGGER event which is a signal from the TRIGGER trigger
source.
5. Executes the device action if the TRIGGER event was detected and the
TRIGGER delay time elapsed.
6. Repeats 4 and 5 until the TRIGGER count reaches the specified count. And then
moves to the ARM layer.
7. Repeats 2 to 6 until the ARM count reaches the specified count. And then moves
to the Idle layer.
This trigger model is applied to two device actions, Transient (source output) and
Acquire (measurement) independently. Two actions can start simultaneously or
separately.
Also for the 2-channel models, two channels can perform synchronous operation or
asynchronous operation.
NOTE Auto key
The Auto key sets the operation of the trigger system to AUTO or off.
In the AUTO status, the channel in the DC output status (On/Off switch is ON)
repeats measurement (Acquire device action) under the predefined trigger
conditions. The Transient device action is not performed.
For the predefined trigger conditions, see “Auto” on page 4-3 .
