4.8.3.9 Initiating Time Acquisition
R&S EK4100 Systems can not be synchronized with the net by means of a TAQ call,
because the request can not be transmitted. Instead, it is required to adjust the SEC-
OM-H time of the receiver according to table 'Dependency of Tolerable Deviation on
Selected Search Pattern (see sect. 4.8.3.6 Selecting the Search Pattern Time)'. A suit-
able search pattern (usually SP192) has to be selected at the receiver and one
NETSYNC or time reference unit. When performing a link setup from that unit to the
receiver, it will be synchronized automatically. The search pattern can be set to a
smaller value after the synchronization was successful.
By means of softkey 'Time ACQ' (time acquisition) the operator can start net time synchro-
nization.

Example of net time synchronization
Press softkey 'Time ACQ Call' to initiate time
acquisition.
1. Press softkey 'Time ACQ Call' to initiate
the time acquisition.
Normally the net time will be adjusted auto-
matically as soon as a communication is tak-
ing place. Therefore manual net time
adjustment as described above will only have
to be performed in the case that communica-
tion was interrupted for quite a time.
When pressing PTT while the TRU (time
reference unit) is answering, the entire ac-
quisition process is aborted.
During acquisition the central area shows:
If acquisition succeeded, the following mes-
sage is displayed:
If acquisition failed, the following message is
