Hi, I have a HP4193A vector impedance meter that I would like to use Labview to read back some values for a impedance sweep. My first problem is that I could not find the driver for this instrument in the NI instrument drivers data base. In MAX I can see my card, however when I try to find instrument, it says instrument not found. All I want to do is read back the impedance and phase for each frequency in the sweep. So just reading back 3 columns of data. However I have to be able to communicate to the instrument first. Any advice on how to get this started would be well appreciated. Thanks.
