Distance to the Transmitter (km) - PZF / AM Receivers only:
In the menu item "Distance to the Transmitter" you can enter the transmitter distance in km, which is used for the
delay compensation of the incoming PZF-signal. The adjustment of the distance should be made as precisely
as possible, because it has a direct influence on the absolute accuracy of the time raster.
PZF Simulation Mode:
This menu allows the user to operate the time server without an antenna. Normally, the NTPD loses synchro-
nization when the antenna or the external reference source is disconnected (red FAIL LED is turned on). By
activating the simulation mode, the corresponding status information for the NTPD is permanently set to SYNC.
This also makes it possible to transmit other times, which have been entered via the menu item "Initialize the
receiver", to the NTPD. In normal cases, the checkbox should remain empty. If this box is activated, the status
"Simulation mode" is displayed under "Info of the receiver" in the main menu.
4.1.1.15 Initialize Receiver
Warm Boot Mode only for GNSS receiver:
This menu allows the user to switch the receiver to WARMBOOT MODE. This may be necessary if the satellite
data in the battery-buffered memory is too old, or if the device is operated at a location that is several hundred
kilometers away from the last operating location, since the calculation of the visibility of the satellites yields
incorrect results.
Cold Boot Modus only for GNSS receiver:
This menu allows the user to reinitialize all GPS system values, this means that all stored satellite data will
be deleted. Please note that the receiver takes about 15 minutes to read-in the information of the satellites
again, to complete the cold boot!
Coordinates (latitude, longitude, and altitude) *only GNSS receiver:
The absolute position of the GPS antenna can be entered here and can be sent to the GPS reference clock
with "initialize Position". This option is useful when the system is operated at a different location and if started
with the previously battery-buffered satellite data.
Time/Date:
With this function, the reference clock can manually be set to a specific date and time.
