HPPR/2 Baseplate AV4
56 / 92 H172204_1_001
8.2 Description
The standard baseplates have BNC connectors for RF-OUT and LOCK-OUT signals to the
TRANSCEIVER (TRX) in the AQS chassis of the console. The TUNE and RGP-HPPR
signals from the TRX and PSM-A are bundled in cables (4 channels each) and linked via d-
sub connectors to the baseplate. Inside the baseplate some RGPs are split with resistive
splitters. All cables to the preamplifiers have SMB connectors.
The MAS3 baseplate is functionally the same as the 8CH baseplate. But because it is
mounted on top of the MAS3 UNIT it has a standard preamplifier housing.
