Structure:
tunneling_current: (optional) NX_NUMBER {units=NX_CURRENT}
The tunneling current between tip and sample after application of bias voltage.
calibration: (optional) NX_NUMBER
Calibration of the current measurement (A/V).
offset: (optional) NX_NUMBER {units=NX_CURRENT}
Offset of the current measurement.
gain: (optional) NX_NUMBER

Proportional relationship between the probe output voltage and the actual tunneling current when measuring the tunneling current.
channels: (optional) NX_CHAR
The scan channels are selected by users (in scan contronaller).
rt_frequency: (optional) NX_NUMBER {units=NX_FREQUENCY}
The bandwitdh of the Hardware and/or Software
signals_oversampling: (optional) NX_NUMBER {units=NX_ANY}
(Signals Periods) The Signals Period is the rate at which the signals are ...
(Signals Periods) The Signals Period is the rate at which the signals are transferred to the host computer running the control software. This is usually lower by a factor of 10 than the sampling rate, because an internal oversampling of the signal is done on the real time engine. You can reduce the oversampling down to 1 in order to resolve higher frequencies in the Spectrum Analyzer.
acquisition_period: (optional) NX_NUMBER {units=NX_TIME}
Update rate for several processes like History Graph, Auto-Approach, and for ...
Update rate for several processes like History Graph, Auto-Approach, and for many Programming Interface functions. This is usually set to 20 ms. All additional timings (7-9) can only be integer multiples of this value. They can be set to different values, but the actual timing value will be coerced to a multiple of the Acquisition Period.
animations_period: (optional) NX_NUMBER {units=NX_TIME}
Update rate of animated graphical indicators. These are e.g. some graphs & ...
Update rate of animated graphical indicators. These are e.g. some graphs & sliders. A reasonable value is 40 ms (25 updates per second). Increase this period to reduce the processor load for the graphical user interface, especially on slow computers. This value is purely a user interface update rate and does not affect measurements in any way.
indicators_period: (optional) NX_NUMBER {units=NX_TIME}
Update rate of digital indicators, e.g. the numbers displayed besides each ...
Update rate of digital indicators, e.g. the numbers displayed besides each slider. Here, 3 updates per second, or 300 ms is enough. This value is purely a user interface update rate and does not affect measurements in any way.
measurements_period: (optional) NX_NUMBER {units=NX_TIME}
The Measurements period is the integration time for precise measurements ...
The Measurements period is the integration time for precise measurements (averaging over specified period), mostly used in sweep modules. Examples are recording of a force-distance curve or a resonance of a cantilever. For fast measurements with small steps, a value of 40 ms may be reasonable. For normal use, 300-500 ms is a good value, but for recording a resonance of a high-Q cantilever, values of several seconds might be necessary. Usually this parameter doesn’t need to be set from this module; the sweep modules will set this value according to the sweep timings.
number_of_outputs: (optional) NX_INT
Number of output channels
output_mode: (optional) NX_CHAR
The user output in each monitor mode.
output_value: (optional) NX_NUMBER {units=NX_ANY}
The values for each output channel.
output_name: (optional) NX_CHAR
User outputs whose name can be modified in the corresponding module.
output_slew_rate: (optional) NX_CHAR
The rate at which the one of the signal changes when ramping to the starting ...
The rate at which the one of the signal changes when ramping to the starting point. (V/s)
hardware: (optional) NXfabrication
Hardware type used in circuit, includes hardware manufacturers and type
