Ri3156b_set(query)_sweep_time
Description
This specifies the time that will take the 3156B to sweep from start to stop frequencies. The time does not
depend on the sweep boundaries as it is automatically adjusted by the software to the required interval. At the
end of the sweep cycle the output waveform maintains the sweep stop frequency setting.
