Gets or sets in-band retuning and specifies the current frequency, in hertz (Hz), of the RF downconverter.

Syntax

Namespace: NationalInstruments.ModularInstruments.NIRfsa

public double DownconverterCenterFrequency { get; set; }

Remarks

Specifies a Double representing the in-band retuning and specifies the current frequency.

Valid values are any supported tuning frequency of the NI-RFSA.

If you set this property, any measurements outside the instantaneous bandwidth of the NI-RFSA are invalid. To disable in-band retuning, reset the property or call the ResetDevice method. After you set this property, the downconverter is locked to that frequency until the value is changed or the property is reset. Locking the downconverter to a fixed value allows frequencies within the instantaneous bandwidth of the converter to be measured with minimal overhead, decreasing tuning time.

Exceptions

TypeDescription
System.ObjectDisposedException

The DownconverterCenterFrequency property was accessed after the associated NIRfsa object was disposed.
