Future Plans
Upgrade and debug the existing generic digital multimeter vi application and check with NI PXI-4060 digital multimeter card and stand-alone Keithley 2701 digital multimeter
Provide generic switch (multiplexer) vi application and check with NI PXI-2593 multiplexer card
Check generic scope vi application with NI PXI-5114 digitizer card
