Usage
:TRIGger:BLOCk:DIGitize <blockNumber>
:TRIGger:BLOCk:DIGitize <blockNumber>, "<bufferName>"
:TRIGger:BLOCk:DIGitize <blockNumber>, "<bufferName>", <count>
<blockNumber>
The sequence of the block in the trigger model
<bufferName>
The name of the buffer, which must be an existing buffer; if no buffer is
defined, defbuffer1 is used
<count>
Specifies the number of readings to make before moving to the next block
in the trigger model; set to a specific value or to infinite by setting to INF;
to stop the count, set to
0
; if not specified, defaults to 1
Details
When trigger model execution reaches the block:
1. The instrument begins making a measurement.
2. The trigger model execution waits for the measurement to complete.
3. The instrument places the measurement into the specified reading buffer, which cannot be of the
writable buffer style.
If you are defining a user-defined reading buffer, you must create it before you define this block.
When you set the count to a finite value, trigger model execution remains at the block until all
measurements are complete. If you set the count to infinite, the trigger model executes subsequent
blocks and measurements continue in the background until the trigger model execution reaches
another digitize block or until the trigger model is aborted or re-initialized.
A digitize function (digitize voltage or digitize current) must be selected before you run a trigger model
that contains this block. You cannot have a measure block and a digitize block in the same trigger
model.
Example
TRIG:LOAD "Empty"
TRIG:BLOC:BUFF:CLE 1
TRIG:BLOC:DIG 2
TRIG:BLOC:BRAN:COUN 3, 5, 2
TRIG:BLOC:DEL:CONS 4, 1
TRIG:BLOC:BRAN:COUN 5, 3, 2
Reset trigger model settings.
Clear defbuffer1 at the beginning of the
trigger model.
Loop and take 5 digitized readings.
Delay 1 s.
Loop three more times back to block 2.
At end of execution, 15 readings are stored in
defbuffer1.
