AUTOMATIC CONTROL BLOCK KRUB.468261.001
Application: the block of autocontrol is designed for automatic ring check of the equipment of tropospheric station using microwave signal without changing the input and output frequencies (waves), it can provide precise adjustment of band readjusted filters (BRF) for receiving and transmitting frequencies, and also for evaluation of transmitter power.
