Meinberg PZF600 - Manual (Page 16)

Menu OSZ.ADJ.
The standard version of the PZF600 includes a voltage controlled temperature compen-
sated oszillator (TCXO). Its nominal frequency of 10MHz is adjusted by using two
digital-to-analog converters (DACs). One of them is responsible for the coarse tuning
and the other one for the fine adjustment of the oszillator.
The value for the coarse-DAC is settable in this menu (range: 0...65535).
Changes in this menu should be done by MEINBERG, only!
Menu DAC CLR
The value of the fine DAC is displayed in this submenu.
If the Set button is pressed for approximately two seconds, the DAC is set to its mid-scale
value and the difference to its last value is added to the coarse DAC proportional. This
process is released automatically if the value of the fine DAC exceeds its limits
(0...4095).
This action is reserved for service purposes by MEINBERG, only!
Menu SER. No.
The 12-digit serial number of the PZF600 is displayed in this menu. This number is
helpful to know if the user asks Meinberg for support.
The most significant eight digits of the serial number are displayed first, after pressing the
Set button the last four digits are shown.
