Programmable input threshold is only available with the NI VirtualBench driver. The VirtualBench
application has an input threshold of 1.65 V.
Under most conditions, the logic analyzer can acquire 1 MS of data. Under some
conditions with very high sustained activity on multiple inputs, the logic analyzer may
only capture 4 kS of data.
