Instrument
This is the class for the DSP 7265 lockin amplifier
- property adc1¶
Reads the input value of ADC1 in Volts
- property adc2¶
Reads the input value of ADC2 in Volts
- property dac1¶
A floating point property that represents the output value on DAC1 in Volts. This property can be set.
- property dac2¶
A floating point property that represents the output value on DAC2 in Volts. This property can be set.
- property dac3¶
A floating point property that represents the output value on DAC3 in Volts. This property can be set.
- property dac4¶
A floating point property that represents the output value on DAC4 in Volts. This property can be set.
- property frequency¶
A floating point property that represents the lock-in frequency in Hz. This property can be set.
- property harmonic¶
An integer property that represents the reference harmonic mode control, taking values from 1 to 65535. This property can be set.
- property id¶
Reads the instrument identification
- property mag¶
Reads the magnitude in Volts
- property phase¶
A floating point property that represents the reference harmonic phase in degrees. This property can be set.
- property reference¶
Controls the oscillator reference. Can be “internal”, “external rear” or “external front”
- property 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.
- setDifferentialMode(lineFiltering=True)¶
Sets lockin to differential mode, measuring A-B
- shutdown()¶
Brings the instrument to a safe and stable state
- property 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.
- property 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.
- property voltage¶
A floating point property that represents the voltage in Volts. This property can be set.
- property x¶
Reads the X value in Volts
- property xy¶
Reads both the X and Y values in Volts
- property y¶
Reads the Y value in Volts
