R-GPIB Commands
Introduction to the R-GPIB Commands
With the knowledge of R-GPIB command syntax, you can design an R-GPIB
program to do the following tasks:
Start the TDSUSB2 application
Recognize an active application with R-GPIB protocol
Program and read the application setup parameters
Sequence measurements
Generate reports
Guidelines to R-GPIB Programming
The application includes an example of an R-GPIB program for your reference as
a program example. Your R-GPIB program should comply with the following
guidelines:
The application startup must complete before sending additional R-GPIB
commands to the application (see example).
To generate reports, first check whether the sequencer state is "Ready".
Appropriate delay (for example: 2 secs) should be maintained between
commands.
The status variable should be checked to ensure that an error has not
occurred because of a measurement command problem.
R-GPIB event queue needs to be monitored. Make sure the event queue is
clear before sending the next R-GPIB command to prevent event queue
overflow.
Commands are case and space sensitive. Your program will not operate
correctly if you do not follow the capitalization and spacing precisely.
