Hi.
I've been trying to use USB to control an Siglent SDG1020 function generator but haven't been able to see the instrument neither in NI MAX nor in LabVIEW.
I checked the drivers in device manager and it is not the NI driver (brus.sys). When installing the device driver system finds the manufacturer .inf –file and then asks for the appropriate .sys – file and the only accepted .sys file in that case is a manufacturer driver brus.sys (I also tried to change the device driver to ausbtmc.sys but with no success (windows refused with the message “No device specific information found”)). After the driver installation the device shows up in the device manager tree under the branch “USB Device Controllers” as a “USB Test and Measurement Device Controller”.
I also tried to do the same with the Rigol oscilloscope. With no success. The only difference was the driver system installed by itself (ausbtmc.sys located in windows/susten32/drivers) and the device shows up in the device manager as USB Test and Measurement Device (IVI). NI MAX and NI LabView was not able to recognize the device. (I use NI LabView 2015 and NI VISA 14.0.1)
Everything went well (literally as it is shown in this video: http://www.ni.com/webcast/1434/en/) only with the Tektronics oscilloscope.
As an operating system I’m using Windows XP Home Edition SP3 x86.
I will be gratefull for any replay.
