GPS-System 6842 |
|
The model 6842 is an euroboard with display and key-pad. These boards can be used worldwide to synchronize computer systems and controls. The unit is synchronized by the satellite navigation system GPS which guarantees the worldwide distribution of precise time, frequency and position.
Model 6842G10 GPS plug-in board 100 x 160 mm, with LCD-display and key-pad, board width 20TE, completely configurable over the key-pad.
Models 6842Gx1,...x2,...x3: "Stand-alone Systems" consisting of:
We can optionally offer a standard frequency-package unit for model 6842. The TTL frequency output is 100 Hz to 10 MHz adjustable in steps of 1 Hz. The sine frequency of 100-2000 Hz at the output is precisely synchronized to the PPS pulse. Due to the adjusting control of the TCXO during satellite reception a short time accuracy of 1 x 10-9 (100 sec) and a long time accuracy of 1 x 10 -11 (1 month) can be reached.
Up to two of the following boards can be connected to the internal bus interface.
