Operation
1. General
The TSG400 time signal generator simulates the time signals DCF, MSF, WWVB,
HBG and JJY. Connection of the GPS receiver enables maintain free operation, since
switch to DST is done automatically within the corresponding signals. Operation is
done via buttons, display via four-line, illuminated LCD. In the main menu, all important
parameters such as time, antenna factor, date, time signal and output voltage are easy
to recognize and modify.
2. Button functions
After turning on the TSG400, always the main menu is shown in the display. The
values that have to be adjusted can be chosen by using the buttons
and The chosen value is indicated by the cursor (underline). The cursor will only
move to positions, where something can be adjusted. The actual adjustment of any
values is done with the buttons and
In some adjustments, by pushing and continuously (>1s), a fast mode can be
activated. To enter a different mode, push the adequate button.

4. GPS SYNC.
To start the GPS SYNC., push “GPS SYNC”
button and connect the C-MAX “GPS100” unit by
using the RJ45 GPS/SYNC. connector at the left
side of the front panel.
The GPS mode will allow different operating options. Available are the options “Sync sec”
and “Sync Time”. If “Sync sec” is set to ON, the change over of the second is adjusted
exactly to the change over of the second of UTC time. If this feature has successfully
finished, will be displayed in the upper right corner of the display. If, in addition, “Sync
Time” is set to ON, the time that is supplied by the GPS receiver will be calculated into local
time (exception: WWVB) and be transmitted as time and date. The calculation will also take
possible summer time settings into consideration. If the GPS receiver is connected, the
recently transmitted values of the second will be displayed. If the GPS receiver is not
connected XX will be displayed in the same position.
If “Sync Time” is chosen, “Sync sec” will be turned on automatically.
If “Sync sec” is activated, an automatic fine tuning of frequency and time pulse will be done in
addition to adjustment of the second impulse to UTC.
A precision of ±0.1ppm will be accomplished after max. 30 minutes. If a highly deviating
value has been adjusted previously, the display “locked” might appear and disappear in
uneven periods.
NOTE:
Before disconnecting the RJ45 connector, the GPS SYNC must be switched OFF or the whole unit must be
turned OFF.

7. Summer time / winter time adjustment
In the protocols of DCF77, MSF and WWVB the switch from summer time to winter time and
vice versa is intended. The switch is done automatically by the TSG400. Therefore, the
TSG400 has to be turned on during the period of the switch over.
7.1 Switch in DCF
Base condition for accurate switch of time is, that the TSG400 is adjusted to the
currently transmitted time. In order to switch to summer time, the TSG400 has to be
adjusted previously to winter time. If the date is the last Sunday in March, at 01:00 the
bit TCA is set as an indication for the change. At 02:00 the hours will be set to 03:00,
the signal bit summer time / winter time will be set to summer time and the TCA bit will
be deleted.
To switch to winter time, the TSG400 has to be adjusted previously to summer time. If
the date is the last Sunday in October, at 02:00 the TCA bit is set for the switch over.
At 03:00, the time is re-adjusted to 02:00, the signal bits will be set to winter time and
the TCA bit will be deleted.
7.2 Switch in HBG
Base condition for accurate switch of time is, that the TSG400 is adjusted to the
currently transmitted time. In order to switch to summer time, the TSG400 has to be
adjusted previously to winter time. If the date is the last Sunday in March, at 01:00 the
bit TCA is set as an indication for the change (see 3.3 and 3.3.1). At 02:00 the hours
will be set to 03:00, the signal bit summer time / winter time will be set to summer time
and the TCA bit will be deleted.
To switch to winter time, the TSG400 has to be adjusted previously to summer time. If
the date is the last Sunday in October, at 02:00 the TCA bit is set for the switch over.
At 03:00, the time is re-adjusted to 02:00, the signal bits will be set to winter time and
the TCA bit will be deleted.
7.3 Switch in MSF
Base condition for accurate switch of time is, that the TSG400 is adjusted to the
currently transmitted time. In order to switch to summer time, the TSG400 has to be
adjusted previously to winter time. If the date is the last Sunday in March, at 00:00 the
TCA bit is set as indication for the change (see 3.3 and 3.3.2). At 01:00 the hours will
be set to 02:00, the summer time bit will be set within the protocol and the TCA bit will
be deleted.

To switch to winter time, the TSG400 has to be adjusted previously to summer time. If
the date is the last Sunday in October, at 01:00 the TCA bit is set for the switch over.
At 02:00, the time is re-adjusted to 01:00, the signal bits will be set to winter time and
the TCA bit will be deleted.
7.4 Switch in WWVB
Base condition for accurate switch of time is, that the TSG400 is adjusted to the
currently transmitted time. In order to switch to summer time, the TSG400 has to be
adjusted previously to winter time. If the date is the first Sunday in April, at first bit 57
will be set at 00:00 UTC time within the time protocol. With the set bit 57 and the not
yet set bit 58 this day is marked as the day for the switch over from summer time to
winter time. All watches and clocks must now do the change automatically, according
to the corresponding point of time in their time zone. On the following Monday, the bit
58 will be set also. Then, the switch over is finished.
To switch to winter time, the TSG400 has to be adjusted previously to summer time. If
the date is the last Sunday in October, at 00:00 UTC time the bit 57 is reset within the
time protocol. Due to the reset bit 57 and the still set bit 58, this day is marked as the
day for switch over from summer time to winter time. All watches and clocks must now
do the change automatically, according to the corresponding point of time in their time
zone. On the following Monday at 00:00 UTC time, bit 58 is also reset. Then, the
switch over is finished.

TSG 400 – Hardware calibration
In this mode the base settings of the equipment can be adjusted.
We recommend a re-calibration every 12 month. This calibration can be done in the C-
MAX calibration facilty or in an other calibration facility using the calibration standards
described in the attached “Calibration Certificate”.
To allow an indipendent calibration facility to calibrate this unit we have put down the
instruction below:
To activate the HARDWARE CALIBRATION MODE of the TSG400, the
buttons and PULSE/CARRIER must be pushed >2 seconds.
The different settings for calibration can be selected with the and buttons. To exit the
calibration mode, the TSG400 has to be turned off.
