RFmxSpecAn ACP Configure Offset VI
- Updated2025-10-13
- 3 minute(s) read
Configures an offset channel on one or both sides of carrier with center to center spacing as specified by the offset frequency and offset frequency definition. In case of multiple carriers, offset frequency is relative to the closest carrier.
Use "offset< n >" as the selector string to configure this VI.

Inputs/Outputs
Selector String
—
Selector String specifies the selector string comprising of the signal name and offset number. If you do not specify the signal name, the default signal instance is used. The default value is "offset0". Example: "offset0" "signal::sig1/offset0" You can use the RFmxSpecAn Build Offset String2 VI to build the selector string.
Instrument Handle In
—
Instrument Handle In specifies the RFmx session refnum. Instrument Handle In is obtained from the RFmxInstr Initialize NIRFSA VI.
Offset Frequency (Hz)
—
Offset Frequency specifies the center or edge frequency, in Hz, of the offset channel, relative to the center frequency of the closest carrier as determined by the ACP Offset Freq Definition property. The sign of offset frequency is ignored and the Offset Sideband parameter determines whether the upper, lower, or both offsets are measured. The default value is 1 MHz.
Offset Sideband
—
Offset Sideband specifies whether the offset segment is present on one side, or on both sides of the carriers. The default value is Both.
Offset Enabled
—
Offset Enabled specifies whether to enable the offset channel for ACP measurement. The default value is True.
error in (no error)
—
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
Instrument Handle Out
—
Instrument Handle Out passes a reference of your RFmx session to the next VI.
error out
—
error out contains error information. This output provides standard error out functionality. |
