Application of Status Report System
The status report system is used to monitor the status of one or more instrument(s) in the test system. In order to properly realize the
functions of the status report system, the controller in the test system must receive and evaluate the information of all instruments.
Standard methods to be applied include:
1) Service request (SRQ) sent by the instrument.
2) Series query sent by the controlled to all instruments in the bus system, aiming to find the sender and causes of service request.
3) Parallel query of all instruments.
4) Query of specific instrument statuses with programmed commands.
For specific operations, refer to "2.1.5.4 Application Status Report System" of the program control manual.
