USB Test and...When the USBTMC requests are correctly implemented the device will show up in NI-MAX and can be used by NI-VISA. Sending commands to the device can be done using VISA write and receiving data by VISA read. During debugging, NI-SPY can be of some help and monitoring the received commands via RS232 may be of some help too.

    Then, if you'd like to provide some users with a function and attribute based interface, you can write an IVI driver on top of VISA. This works particularly well if one or more of the IVI instrument classes cover the functionality your users need; they use the well-known class driver, which delegates to you instrument-specific driver.

    Nov 13, 2019 · I don't necessarily want to deal with NI VISA. I started to look into USBTMC and while it seems lighter weight, it would still require significant work/research. And a likely bigger problem is that I don't have ready access to a Siglent device to test. So, that said, I'd like to see if anyone else is motivated to help out. Agilent IO Libraries Suite is a collection of libraries and utility programs. The IO libraries (SICL, VISA, and VISA COM) enable instrument communication for a variety of development environments (Agilent VEE Pro, Microsoft Visual Studio, etc.) that are compatible with GPIB, USB, LAN, RS-232, PXI, AXIe, and VXI test instruments from a variety of manufacturers.
