AMP STATE Indication of the amplifier state (ON /
OFF)
In the RF unit the following parameters can be defined and checked:
RF-UNIT Menu / UP-CONVERTER
Parameter Remark
VISION CARRIER FREQ. Indication of the adjusted frequency
CARRIER OFFSET Indication of the adjusted offset
RF-UNIT Menu / BROADBAND AMPLIFIER
Parameter Remark
GAIN CONTROL Selection of the gain control (AUTO /
MANUAL)
MANUAL GAIN Input of the manual gain (0,0 - 25,000 dB)
DEVIATION FROM NOMINAL GAIN Indication of the deviation from nominal
gain
NOTE: This menu entry is not present, if
a RCU 8600 is installed. In this case the
menu entry “DEVIATION FROM
OPTIMAL PA GAIN” appears. This entry
refers to the deviation (in dB) between the
current gain level of amplifier´s AGC and
its optimal gain level. Adjust the exciter
output level to achieve a minimum
deviation. Afterwards press “SET GAIN
TO NOMINAL” and, if desired, switch
GAIN CONTROL to AUTO. If a WEEPY is
visible, there is no nominal point set for
the current configuration. Press “SET
GAIN TO NOMINAL” to set a nominal
point, and the WEEPY will vanish.
SET GAIN TO NOM. PERFORM key for setting gain to nominal
value
NOTE: This key is for compensating
output deviations (e.g. due to ageing or
manual adjustment.
