My Keithley 3706A System Switch is now listed in the device manager under USB Devices with Code 52: "Windows cannot verify the digital signature for the drivers required for this device".
As a first step I removed the device from the device manager so it hopefully would reinstall itself. It did'nt.
Now I struggle with the installation of all needet software:
4. Keithley TestScriptBuilder (KTS-850G03.exe) & TSBAddIn_3700S_1.1.7.exe.
But the system switch is always listet as unknown device without driver (Code 28).
What did I miss?
The 3706A is a USBTMC compliant instrument so it can use any generic USBTMC driver. These drivers are included with any vendors VISA communication software layer. I would recommend using NI-VISA for this. The latest version as of today can be downloaded from the following URL.
