Choosing sampling frequency and intermediate frequency
RVP10 does not assume a particular relationship between the A/D sampling frequency and the receiver's intermediate frequency. You can operate at any IF that is at least 2 MHz away from any multiple of half sampling rate. If the IF bandwidth is higher than ~2 MHz (for example, with hybrid pulsing), then IF needs to be ~4 MHz away.
The RVP10 sampling frequency can be set at 5 MHz steps. There are free web tools available for the frequency planning. For example, the following sampling frequencies are optimal for 8 MHz IF bandwidth:
| IF frequency / MHz | Sampling frequency / MHz |
|---|---|
| 60 | 210 |
| 57.5 | 205 |
| 30 | 250 |
