class pymeasure.instruments.agilent.AgilentE4980(adapter, **kwargs)

Bases: pymeasure.instruments.instrument.Instrument

Represents LCR meter E4980A/AL

ac_current

AC current level, in Amps

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)

Run frequency list sweep using sequential trigger.

Parameters:
  • freq_list – list of frequencies
  • return_freq – if True, returns the frequencies read from the instrument

Returns values as configured with mode

frequency

AC frequency (range depending on model), in Hertz

impedance

Measured data A and B, according to mode
