I am trying to control an Agilent 33120A function generator with LabVIEW 2014. I found these drivers: http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=0470714759413BCCE0440003BA7CCD... .I first tried the 2015 drivers but they weren't compatible with 2014. I am now trying to use the 8.2.1 drivers but keep receiving this error "Error -1073807346 occurred at VISA Write in Agilent 33XXX Series.lvlib:Error Query.vi->Agilent 33XXX Series.lvlib:Configure Standard Waveform.vi->Agilent 33XXX Series Generate Frequency Sweep - SW Triggered.vi" when I try to run an example program.
The function generator is not being accessed by other programs, so I don't think anything is trying to communicate over the comport. Does anyone know how to find a 2014 version of these drivers, or how to make the current drivers I found work with my system?

Hello,
this Error usually means there are no listeners at the VISA address specified by the address string.
Here is a link to help you with it.

I know this isn't the issue as I can see the Agile system listening at COM 7.

Looks like the Initialize block sets 1 stop bit (at least my version does), but the device requires 2 stop bits. You might want to edit that block.
