Get Last Calibration Temperature (G Dataflow)

Last Modified: April 2, 2018

Returns the onboard temperature, in degrees Celsius, of an SMC-based oscilloscope at the time of the last self-calibration or external calibration.

The temperature returned by this node is an onboard temperature read from a sensor on the surface of the oscilloscope. This temperature should not be confused with the environmental temperature of the oscilloscope surroundings. During operation, the onboard temperature is normally higher than the environmental temperature.

Temperature-sensitive parameters are calibrated during self-calibration. Therefore, the self-calibration temperature is usually the more important temperature to read.

session in

The instrument handle that you obtain from Initialize External Calibration. The handle identifies a particular instrument session.

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

which temperature

The calibration temperature to return, either the self-calibration or external calibration temperature.

Name Value Description
External Calibration 0 Returns the temperature taken during external calibration.
Self Calibration 1 Returns the temperature taken during self-calibration.

session out

Reference to the NI-SCOPE instrument session to pass to the next node in the program.

error out

Error information.

The node produces this output according to standard error behavior.
