5745A Generator and USB port

[Julien_31]

Hello,

I have downloaded the driver for 5745A generator (I'm using LabVIEW 8.5). I can see on the following web link that it can be piloted by USB.

My problem is very simple : in MAX, USB port is not recognized. So what is the name of the resource which I have to use ? (I mean, for an RS232 port i could choose "COM1" for example. So what should I choose for my USB port ?)

Thank you very much,

Julien

That depends on whether it conforms to the USB Test and Measurement Class (USBTMC) protocol. The LabVIEW Help file provides the following information for what to use for USB instruments for the VISA Resource Name control:

USB INSTR	USB[board]::manufacturer ID::model code::serial number[::USB interface number][::INSTR]
USB RAW	USB[board]::manufacturer ID::model code::serial number[::USB interface number]::RAW

For example:

USB::0x1234::125::A22-5::INSTR	A USB Test & Measurement class device with manufacturer ID 0x1234, model code 125, and serial number A22-5. This uses the first available USBTMC interface of the device. This is usually number 0.
USB::0x5678::0x33::SN999::1::RAW	A raw USB nonclass device with manufacturer ID 0x5678, model code 0x33, and serial number SN999. This uses the device interface number 1.
