Arguments
Returns
Remarks
The PicoScope 3204 oscilloscope model has a simple, 1kHz square wave, signal generator for
scope probe calibration. Therefore only two arguments of this function have any effect:
To switch the square wave on, use a valid
value. To switch the square wave off, use a valid

start the sweep or the frequency generated in a non-sweep mode.

stop_frequency, the required stop frequency of the sweep, in the range 0 <
freq <1MHz but not necessarily greater than start_frequency. If the start
and stop frequencies are the same, the signal generator will be run with a
constant frequency. This agument has no effect if used with the PicoScope 3204
variant..
increment, The size of the steps to increment or decrement the frequency by
in a sweep mode. This must always be positive, the start and stop frequencies
will determine whether to increment or decrement. This must be a frequency in
