- 1 minute(s) read
Sets the center or edge frequency, in hertz (Hz), of the offset channel, relative to the center frequency of the closest carrier as determined by the SetOffsetFrequencyDefinition(string, RFmxSpecAnMXAcpOffsetFrequencyDefinition) method. The sign of offset frequency is ignored and the SetOffsetSideband(string, RFmxSpecAnMXAcpOffsetSideband) method determines whether the upper, lower, or both offsets are measured.
Syntax
Namespace: NationalInstruments.RFmx.SpecAnMX
public int SetOffsetFrequency(string selectorString, double value)
Remarks
This method maps to the RFmxSpecAn_ACPSetOffsetFrequency() function in C.
Parameters
| Name | Type | Description |
|---|---|---|
| selectorString | string | Specifies the offset number. Example: "offset0". You can use the BuildOffsetString2(string, int) method to build the selector string. |
| value | double | Specifies the center or edge frequency, in hertz (Hz), of the offset channel, relative to the center frequency of the closest carrier as determined by the SetOffsetFrequencyDefinition(string, RFmxSpecAnMXAcpOffsetFrequencyDefinition) method. The sign of offset frequency is ignored and the SetOffsetSideband(string, RFmxSpecAnMXAcpOffsetSideband) method determines whether the upper, lower, or both offsets are measured. |
Returns
Returns the status code of this method. The status code either indicates success or describes an error or warning condition.
