| Name | PV | Description |
|---|---|---|
| Freq | :PLL:NCO:FREQ_S | When written this will set the PLL NCO to the given frequency. If feedback is running the offset will briefly be forced to zero. |
:PLL:NCO:FREQ | This reads back the current NCO frequency. This PV updates at 10Hz. | |
| Offset | :PLL:NCO:OFFSET | This is the current PLL offset, updated at 10Hz. |
| Gain | :PLL:NCO:GAIN_DB_S | The NCO signal strength is configured here. Clicking here links to NCO Gain Configuration. |
:PLL:NCO:ENABLE_S | This PV turns the NCO output on or off. | |
| Mean | :PLL:NCO:MEAN_OFFSET | This is the mean offset computed over the last full OFFSETWF waveform. |
| Std | :PLL:NCO:STD_OFFSET | This is the standard deviation computed over the last full OFFSETWF waveform. |
| Tune | :PLL:NCO:TUNE | This is the fractional tune computed from the MEAN_OFFSET value and the base frequency. This PV updates when MEAN_OFFSET updates, and is forced to NaN when feedback is not running. |
