I'm trying to write an iGPIB nstrument driver in C.
I have a Driver Template and get the input
So the instrument I want to control is an RF-Amplifier, which is internal two amplifiers, one from 9kHz to 400MHz, the second from 200MHz to 1GHz.
The output is routed into a second Amplifier on a different GPIB address, and in this Amplifier is the RF switch matrix which i have to switch for routing the Output of Amplifier 1 to the right output of Amplifier 2.
Amplifier 2 has the GPIB address of Amplifier 1 plus 1 (e.g. Amplifier 1 address 7, Amplifier 2 address 8).
How can I extract the GPIB address out of the VISAresourceName and set it to GPIB adddress +1?
