The Generic Pulse Waveform allows you to completely define a square wave to apply to a sample. The waveform is shown in the Figure below.
The signal levels are defined by the DC Offset value combined with the Amplitude of the square wave. The minimum value for t1 and t2 is 1 ms. The square wave may be asymmetrical, i.e., t1 and t2 may have different values.
There are three modes of current or potential measurement:
