Mirror Frequency Spectrum (MB-OFDM)

Menu Path: MeasSetup > MB-OFDM Demod Properties > Advanced tab

Default:Clear (see MB-OFDM Standard to Preset Table)

Select Mirror Frequency Spectrum to do frequency inversion before attempting to demodulate the signal, which allows demodulation of frequency spectrums that are mirrored (flipped) about the center frequency.

The display of the spectrum data does not change with this parameter. To mirror the spectrum display, clear the Mirror Frequency Spectrum check box and select the check box for MeasSetup > Frequency tab > Mirror Frequency.

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).
