I'm building a front panel interface for two Agilent E4435B signal generator that need to work together over the GPIB bus. One generator is a jammer and the other is the modulated signal. I would like to use one front panel to talk to both generators but I'm having trouble with getting both GPIB address so I can use them in the program. I'm have done this before for single instrument but not sure how to handle two VISA address so I can switch between the two on one front panel. Any suggestions or examples someone can point me to.
When using two GPIB devices, you need to program your application so that your devices are synchronized. That is, you do not want two reads/writes occurring at the same time. There is a good example of this (and accessing two addresses) in the Example Finder. In your VI, go to Help -> Find Examples... and then search for an example called "Basic 2 Port Serial Write and Read.vi". This example should help you to get started. Best of luck,
