Mirror Frequency Spectrum (GSM/EDGE/EDGE Evolution)

Default: Cleared

Mirror Frequency Spectrum correctly demodulates signals whose frequency spectrums are mirrored (flipped) about the center frequency.

The pre-demodulation Time, Inst Spectrum, and Spectrum traces will not be affected when this parameter is selected. To mirror these pre-demodulation traces as well as demodulation traces, clear the demod-specific Mirror Frequency Spectrum check box here and select the MeasSetup > Frequency tab > Mirror Frequency check box.

External Down Converter

When using an external down converter, specify the User Correction Spectrum "Normal" parameter and make sure the "Mirror Spectrum" parameter is not selected (Input > User Correction > Spectrum > "Normal") and use the Mirror Frequency parameter in the MeasSetup Frequency dialog box instead (MeasSetup > Frequency > Mirror Frequency).
