Notes:
1. The
Professional Demodulator offers two additional
demodulation modes, DSB and ISB.
2. The
Wide-FM Option provides a separate wide-FM
demodulator. The wide-FM demodulation is performed in hardware,
using conventional hardware-based demodulation techniques, in
order to ease the requirement of PC processing power which would
otherwise be required for a signal of this bandwidth. In other
words, the Wide-FM Option is an entirely separate
receiver on its own right.
3. The
Professional Demodulator offers continuously
adjustable IF bandwidth from 100 to 15000 Hz in all narrow-band
modes. The optional Wide-FM demodulator has a fixed bandwidth of
230 kHz.
4. The AM sensitivity is specified at 30%
modulation for 10 dB S/N ratio. For 80% modulation, typical AM
sensitivity of WR-G305i is 0.60 µV in 0.15-500 MHz range. The
Professional Demodulator improves sensitivity
further by making it posible to extend filter lengths, and
adjust the IF bandwidth for optimum reception of the received
signal: This results in a typical improvement by 2-3 dB on AM/SSB/FM
and up to 10 dB on CW.
The WR-G305e receiver is truly one of the most
sensitive receivers available, yet with an excellent dynamic
range.
The following table illustrates the effect of
the AM modulation depth and the Professional Demodulator on
typical sensitivity figures:

10 dB S/N) |

| Standard |
1.7 µV |
0.6 µV |
| Professional |
1.5 µV |
0.45 µV |
