Keysight 53147A/148A/149A Operating and Programming Guide
Of the three procedures discussed here, this one is the most flexible, but it is also
the most complex:
Set up program to specify service routine and enable interrupt when SRQ is
asserted:
The program can do other things while it is waiting for SRQ.
When SRQ occurs, and the instrument has been identified as the cause of the
SRQ, ask for the data:
:AVERAGE:COUNT 50
:AVERAGE ON
*ESE 1
*SRE 32
On INIT, take N measurements.
Enable averaging.
Summarize OPC bit for Status Byte Register.
SRQ when event summary bit is 1.
:INIT
*OPC
Start measurements.
Enable OPC bit.
DATA?
Ask for data.
