  `ac_voltage`

    AC voltage level, in Volts

  `aperture`(time=None, averages=1)

    Set and get aperture.

    Parameters:

    - time – integration time as string: SHORT, MED, LONG (case insensitive); if None, get values
    - averages – number of averages, numeric

  `freq_sweep`(freq_list, return_freq=False)
