I am trying to perform GPIB communication with an old HP 8657b (Agilent) function generator. The gpib connection is achieved through a NI board.
Using tmtool, I am able to connect to the device. Unfortunately, I cannot send order to it or read its buffer.
Typically the command I gonna pass are:
gene = gpib('ni',1,7);
fprintf(gene,'"FREQ:CW 500 MHz;\n"');
But as you might imagine the device remains silent.
First, I wonder if I am talking to the device properly? Second, since this is an old device, is the driver already installed on matlab, or should I install it? In the latter case, how can I check this? What is the procedure to install a driver and where do I find it?
