Adjust Oscillator Frequency Calibration (G Dataflow)

Last Modified: August 3, 2017

Calculates calibration constants pertaining to the oscillator.

During external calibration, you can generate sine waves and take measurements of the resulting output frequencies. Using the desired and measured frequencies of the output waveform, this node calculates the appropriate calibration constants and, when the calibration session is committed, stores them in the onboard EEPROM.

datatype_icon

session in

Handle that identifies your instrument session previously allocated by Initialize External Calibration.

datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

desired frequency in hz

Expected frequency of the output waveform in Hz.

datatype_icon

measured frequency in hz

Actual (measured) frequency of the output waveform in Hz.

datatype_icon

session out

Reference to your instrument session to wire to the next node.

datatype_icon

error out

The node produces this output according to standard error behavior.
