I am having some problems with the NI IVI driver for the Agilent 33120A Function Generator. I am controling the 33120 through the serial port and I am able to control it. The problem I am having is that every time I want to change just one thing such as the frequency, the generator resets. I am using the Inialize VI from the driver set, then into the Write Instrument Data VI then the Close. I have tracked the problem down to the Initalize VI. Every time it is run, the generator resets, even though I have both the query and reset inputs set to False. I am not sure if there is a way around using the Initalize VI, since I have no experience with the IVI drivers. Using GPIB is not an option, since the application will be stand alone a
nd I do not wish to force the GPIB issue. I have attached a VI for changing duty cycle as an example. Any help would be appreciated.
