Some quick preliminary results. Onboard TCXO operating at 40MHz, internal PLL multiplier of 25x. Output at 200MHz.
| Carrier offset | Phase noise |
|---|---|
| 100 Hz | -94.927890 dBc/Hz |
| 1 kHz | -102.364708 dBc/Hz |
| 10 kHz | -107.375432 dBc/Hz |
| 100 kHz | -113.332989 dBc/Hz |
| 1 MHz | -126.497115 dBc/Hz |
This is a little worse than one might expect from the datasheet, although unclear why.
Spectrum -- note the TCXO reference spurs at 40MHz, down 70ish dB.
