DPO3034 - Connecting to a PC via USB
(1/1)
Tony_G:
Hey All,
I dumpster-dived a DPO3034 marked "Does not communicate with the PC". It seems to run fine standalone and if I connect the Ethernet port then I can see it as a GPIB device and it reacts to IDN.
However, when I plug the USB host into my PC, I see an error - The dreaded Code 43 - A request for the USB device descriptor failed.
Now this isn't a problem for me per see as I have a bench LAN and mostly use the NI-VISA software on my PC but I'm wondering if I'm doing or missing anything when connecting it - I don't think so as it is supposed to be a USBTMC instrument and the NV-VISA software should provide a driver for that but I thought I'd check.
Thoughts?

you wont miss a thing to me, if your lan port is okay
usb is not for very intensive data polling .... i use lan on my stuff
code 43 could mean HW failures, not sure its driver related, check in device manager for the vid pid error and try to find if you need drivers
for visa related i se Rohde schwartz drivers, lightweight and practical, you have tools to communicate with instruments, had bench dmm with usbtmc, and worked very well

Thanks - I generally use GPIB via a NI GPIB-ENET/1000 or simply LAN as you say, so while a number of my instruments do have USB I've never used it.
I think I'm going to just ignore it for now.
