"""
This short example shows how the Oscilloscope class can be used. Assuming a sinusoid signal of ~200-400 mV amplitude and up to a few kHz frequency as input on channel 4 (C4) and an external trigger,
this script asks for the ip address, attempts to connect to the oscilloscope with that address, creates a single beep sound, then sets up a 1s measurement to read out the amplitude of the
aforementioned signal. Returns a list containing a single float, the amplitude in V.
