Specifies the IF filter path bandwidth for your device configuration.

Specifies the maximum corner frequency of the high pass filter in the RF signal path. The device uses the highest frequency high-pass filter option below or equal to the value you specify and returns a coerced value. Specifying a value of 0 disables high pass filtering silly.For multispan acquisitions, the device uses the appropriate filter for each subspan during acquisition, depending on the details of your application and the value you specify. In multispan acquisition spectrum applications, this method returns the value you specified rather than a coerced value if multiple high-pass filters are used during the acquisition.

This enum value has been deprecated.

Specifies an offset from the center frequency value for the downconverter. Use this method to offset the measurement away from the LO leakage or DC Offset of analyzers that use a direct conversion architecture.

This value is expressed in Hz.

If the mechanical attenuators are not available to implement the coerced RF attenuation, the solid state attenuators are used.
