FM) and CW modes, with fixed bandwidths.

There is a real-time spectrum scope which shows the actual situation on the received band.

An interesting feature is Audio AGC (in addition to the existing hardware IF AGC).

g303 professional demodulator

This advanced demodulator is offered as an optional extra. It adds DSB and ISB modes, additional Audio AGC

settings and continuous IF bandwidth adjustment (from 1Hz to 15 kHz). There are also user-definable IF

bandwidth preset buttons at the bottom.

Many more exciting facilities are hidden under the Setup button: Optimized filter settings make it possible to

increase the receiver sensitivity typically by 2 dB on AM, SSB and FM; and by up to 10 dB on CW.

The left part of the Setup window is similar to the Standard Demodulator. The right one contains some surprises:

The demodulator parameters (such as the digital filter length) can be adjusted by the user. There are separate

"tabs" for independent setting of each of the eleven demodulation modes.

Clicking on the View Demodulator Structure button discloses an interactive diagram of the demodulator

structure:

At the top there is a block diagram showing the structure of the currently selected demodulator (each modulation

mode has its own demodulator). Below, there are also two spectrum analyzers. Left clicking on any of the color

points inside the block diagram will connect the left spectrum analyzer to the associated point (the color of the

point will change to red). Right clicking will connect the right spectrum analyzer (the point color will turn blue).

At bottom left, there is a Vector Voltmeter showing amplitude and phase differences between the two selected

points, at the cursor frequency.

There are also THD (total harmonic distortion) and SINAD (signal-plus-noise-plus-distortion to

noise-plus-distortion) meters, to complement this unique instrument.
