SQZ CLF VCO
A new VCO for the CLF was installed. This VCO has a higher modulation bandwidth compared to the previous VCXO at the cost of more low frequency phase noise.
The SSB phase noise according to the data sheets:
| Frequency | New VCO | Old VCXO |
|---|---|---|
| 100Hz | -103 dBc | |
| 1kHz | -110 dBc | -133 dBc |
| 10kHz | -132 dBc | -148 dBc |
| 100kHz | -150 dBc | -158 dBc |
