Automatic control couples the attenuation to the reference level. Note that setting the attenuation using this command automatically sets the attenuation coupling to “MANUAL”, thereby allowing it to be defined independently of the reference level.

Set AM/FM Demodulation – Control Byte #145 (91h)
Description: Sets the AM/FM/SSB Demodulation state. This command is also used to set the type of Modulation, volume, Demodulation Frequency, BFO Adjust (SSB only) and the Demodulation time. On turning demodulation ON, after exiting remote, at the end of every sweep, demodulation is performed at the Demodulation frequency for a period of time specified in the Demod Time.

279If Option 6 is installed and the frequency converter module is attached, the frequencies should be scaled by the scale factor of the module. If the module is not attached, the frequencies are sent in Hz. Use Control Word A203 to determine whether a module is attached and the appropriate scale factor.
