Device Track ID
DPM 1 JTH0500101
DPM 2 JTH0500105
PSU 1 JTH0500200
Units are not present:
ATCC 1 JTH0500201

Tuning the MTCC in a BTS in Tetra Application Mode

The Manually Tuned Cavity Combiner (MTCC) can have 2 or 4 inputs. The TX output of each BR is connected to an
input on the MTCC. The output of the MTCC is connected to the Antenna Port of the BTS via the TX-path of a
duplex filter. A configuration file has been uploaded to the Site Controller, defining the TX frequencies of all the
BRs.
Equipment: High Power Power Meter (PM) like Stabilock 4032, which can handle up to 120W. Service computer.
Procedure:
1 Calibrate the PM and set the frequency to the center frequency of the duplex filter. Set the PM to display Watts.
2 Connect the PM to the TX antenna connector of the BTS.
