reference_amplitude: (optional) NX_NUMBER {units=NX_ANY}
The electrical (voltage) or mechanical (displacement) amplitude of the referen ...
The electrical (voltage) or mechanical (displacement) amplitude of the reference (drive) signal used to oscillate the cantilever.
It is typically the interaction force or electrical voltage applied to the excitation piezo that drives the cantilever at or near its resonance frequency.
Note: At least one from reference_amplitude, reference_frequency, or reference_phase is expected.
reference_frequency: (optional) NX_NUMBER {units=NX_FREQUENCY}
The reference frequency (also called drive frequency or resonance frequency) o ...
The reference frequency (also called drive frequency or resonance frequency) of the cantilever.
Note: At least one from reference_amplitude, reference_frequency, or reference_phase is expected.
reference_phase: (optional) NX_NUMBER {units=NX_ANGLE}
The reference phase of the cantilever oscillator. ...
The reference phase of the cantilever oscillator.
Note: At least one from reference_amplitude, reference_frequency, or reference_phase is expected.
frequency_harmonic: (optional) NX_NUMBER {units=NX_DIMENSIONLESS}
The harmonic (e.g., second harmonic of the fundamental frequency) frequency of ...
The harmonic (e.g., second harmonic of the fundamental frequency) frequency of the cantilever.
phase_shift: (optional) NX_NUMBER {units=NX_ANGLE}

The phase difference between the reference signal of cantilever and response signal.
frequency_shift: (optional) NX_NUMBER {units=NX_FREQUENCY}
Shift in the resonance frequency of the cantilever.
frequency_cutoff: (optional) NX_NUMBER {units=NX_FREQUENCY}
The cutoff frequency of the cantilever.
frequency_bandwidth: (optional) NX_NUMBER {units=NX_FREQUENCY}
The bandwidth of the resonance frequency.
amplitude_setpoint: (optional) NX_NUMBER {units=NX_ANY}
The amplitude setpoint is a target or desired electrical or mechanical amplitu ...
The amplitude setpoint is a target or desired electrical or mechanical amplitude obtained in the feedback loop of the cantilever’s piezo system. It is constantly compared to the RMS amplitude of the cantilever’s oscillation to adjust the drive voltage and maintain a stable oscillation amplitude.
This field is same as the reference amplitude in the non-contact mode.
frequency_setpoint: (optional) NX_NUMBER {units=NX_FREQUENCY}
The frequency setpoint is the target or desired frequency of the cantilever. ...
The frequency setpoint is the target or desired frequency of the cantilever. This field is same as the reference frequency in the non-contact mode
active_frequency: (optional) NX_NUMBER {units=NX_FREQUENCY}
The active frequency of the cantilever to start the experiment.
