Operate Process Variables
The following table lists the PVs for the instrument operation involving the controls for
waveform acquisition.
Process Variable
Type
Values
Description
setOpInitCont
getOpInitCont
bo
bi
0 or 1
The instrument’s continuous acquisition mode:
0 = single capture
1 = continuous capture
OpInitiate
bo
0 or 1
Initiate waveform acquisition.
OpAbort
bo
0 or 1
Aborts waveform acquisition.
OpForceCap
bo
0 or 1
Force waveform capture (all triggers):
0 = no operation
1 = force capture
A transition from 0 to 1 causes the waveform acquisition
to complete, after which the value returns to 0
OpAutoLoad
bo
0 or 1
Download new waveforms during continuous
acquisition.
0 = no operation
1 = download
A transition from 0 to 1 causes the download, after
which the value returns to 0
OpArm
bo
0 or 1
Manual arm for software arm source:
0 = disarm
1 = arm
This only applies when the arm source is set to software
OpAutoSetup
bo
0 or 1
Automatically setup range, offset, trigger level for
enabled channels:
0 = no operation
1 = force auto setup
A transition from 0 to 1 causes the auto setup, after
which the value returns to 0
OpCompleteEnable bo
0 or 1
Enable the operation complete flag to be set when all
pending operations have completed.
0 = operation complete register is disabled
1 = operation complete register is enabled until
pending operations complete, then is
disabled again.
This enables the operation complete bit, which can be
read in Status as well as OPC driven outputs.
getOpComplete
bi
0 or 1
Check to see if all pending operations have completed.
0 = all pending operations have not completed
1 = all pending operations have completed.
