# DSP 7265 Lock-in Amplifier

class `pymeasure.instruments.signalrecovery.``DSP7265`(resourceName, **kwargs)

  Bases: `pymeasure.instruments.instrument.Instrument`

  This is the class for the DSP 7265 lockin amplifier

  `adc1`

    Reads the input value of ADC1 in Volts

  `adc2`

    Reads the input value of ADC2 in Volts

  `dac1`

    A floating point property that represents the output value on DAC1 in Volts. This property can be set.

  `dac2`

    A floating point property that represents the output value on DAC2 in Volts. This property can be set.

  `dac3`

    A floating point property that represents the output value on DAC3 in Volts. This property can be set.

  `dac4`

    A floating point property that represents the output value on DAC4 in Volts. This property can be set.

  `frequency`

    A floating point property that represents the lock-in frequency in Hz. This property can be set.

  `harmonic`

    An integer property that represents the reference harmonic mode control, taking values from 1 to 65535. This property can be set.

  `id`

    Reads the instrument identification

  `mag`

    Reads the magnitude in Volts

  `phase`

    A floating point property that represents the reference harmonic phase in degrees. This property can be set.

  `sensitivity`

    A floating point property that controls the sensitivity range in Volts, which can take discrete values from 2 nV to 1 V. This property can be set.

  `slope`

    A integer property that controls the filter slope in dB/octave, which can take the values 6, 12, 18, or 24 dB/octave. This property can be set.

  `time_constant`

    A floating point property that controls the time constant in seconds, which takes values from 10 microseconds to 50,000 seconds. This property can be set.

  `values`(command)

    Rewrite the method because of extra character in return string.

  `voltage`

    A floating point property that represents the voltage in Volts. This property can be set.

  `x`

    Reads the X value in Volts

  `xy`

    Reads both the X and Y values in Volts

  `y`

    Reads the Y value in Volts
