Set the period for pulses. The PER[1|2]? query returns the period of the
pulse waveform in seconds. The specified period must be greater than the
sum of the pulse width and the edge time.
This command affects the period (and frequency) for all waveform functions
(not just pulse). For example, if you select a period using the PER[1|2]
command and then change the function to sine wave, the specified period
will be used for the new function. MIN selects the lowest actual possible
period allowed for the selected function. MAX selects the highest actual
possible period allowed.
