PZF510 with OCXO
The optional deliverable OCXO of the PZF510 operates with a single +5V power
supply. This voltage should be sourced by a stable supply to avoid drifting of the
frequency caused by the power supply. Because of the low heating time of the
oszillator, the OCXO can be regulated to the specified precision approximately 10
seconds after power-up. During operation the OCXO-version behaves like the TCXO-
type but with better accuracy.
ACCURACY: +/- 1·10 -9 short term stability for standard frequencies and
synthesizer (up to 10kHz)
+/- 2·10 -8 per day without receiption of DCF77
