1. I need a Virtual instrument that triggers a sweep to source very low voltages (my instrument is not a fuction generator, so I can´t just send a square wave, it is a presicion instrument able to source very low voltages in the order of micro-volts, so I need to program a sweep which to emulate the square wave, I´ve already done it from the instrument itself), I need to visualize the voltage sourced in a plot or graph, and be able to change Amplitud, period if possible.
2. I need another virtual instrument to store the voltage measued by another Keithley Instrument, a nanovoltmeter. This informations should also be stored and visualized in a graph or plot.
