To ensure the most efficient use of the Service Request (SRQ)
mechanism provided by USBTMC-USB488, first check that the RQS
bit in the Status Byte is clear. To do this, perform a serial poll of the
Product before you send any commands that could generate SRQ
events. This only needs to be done once in your program/procedure.
Check communications can be established:
Write *IDN?
Read the response
Clear registers and read the status byte:
Write: *CLS;*RST
Write *ESE 0
Write *SRE 191
Read the status byte (Serial POLL)
Before you proceed, set the event and status registers as required.
