Trying to connect an hp8591c to the benchlink software does anyone have a link that might make this a little easier, we are using a usb to serial adapter, and as far as I know the settings are correct, I just cant find the analyzer on the laptop through benchlink.

Of course you need to be sure that the instrument baud rate is the same.
