instrument handle

The instrument handle that you obtain from the IviDownconverter Initialize or IviDownconverter Initialize With Options Node. The handle identifies a particular instrument session.

Default: None

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

frequency sweep mode

Specifies the sweep mode of the RF input signal. The driver uses this value to set the IviDownconverter Frequency Sweep Mode [FSW] property.

Name Description
IVIDOWNCONVERTER_VAL_FREQUENCY_SWEEP_MODE_NONE The RF input is a non-swept signal (continuous wave).
IVIDOWNCONVERTER_VAL_FREQUENCY_SWEEP_MODE_SWEEP Sweeps the RF input signal frequency in analog form (non-stepped).
IVIDOWNCONVERTER_VAL_FREQUENCY_SWEEP_MODE_STEP Sweeps the RF input signal frequency in steps.
IVIDOWNCONVERTER_VAL_FREQUENCY_SWEEP_MODE_LIST Uses a list to sweep the RF input signal frequency.

Default: IVIDOWNCONVERTER_VAL_FREQUENCY_SWEEP_MODE_NONE

datatype_icon

trigger source (None)
