The transmitted signal in the sideband (SSB) or sidebands (DSB) is further decimated in powers of two before being applied to the spectrum analyzer. The frequency span is the audio sample rate (48 kHz) divided by the decimation factor. The transmitted signal in the sideband (SSB) or sidebands (DSB) is further decimated by a power of two before being applied to the channel spectrum display. Thus the frequency span of the spectrum display is the audio sample rate (48 kHz) divided by the decimation factor.

The modulating signal is bandpass filtered (SSB) or lowpass filtered (DSB) before being multiplied by the local oscillator NCO. This is the upper limit of the filter. The modulating signal is bandpass filtered (SSB) or lowpass filtered (DSB) before being multiplied by the local oscillator NCO. This is the upper limit of the filter in absolute value.
When this limit is positive the signal is transmitted in the upper sideband (USB). When this limit is negative the signal is transmitted in the lower sideband (LSB). When this limit is positive the signal is transmitted in the upper sideband (USB). When this limit is negative the signal is transmitted in the lower sideband (LSB).
