Description:
T6 enables the filters in the four IF Receiver (T5)
Modules and four Spectral Line IF (T7) Modules
to be selected either manually or under computer control, and the gains
of the same units to be set manually or controlled by a.l.c. loops. Manual
control is effected through front panel switches and potentiometers on
the T6 module. An interface with a Data Set (M1)
enables the filter select signals to be received from the computer, and
the voltages of the a.l.c. signals and the outputs of the IF level monitoring
detectors to be fed back to the computer. |
