VSWR Alarm
(Read Only in Run Mode)
VSWR Alarm: XX.X dB
The VSWR Alarm Threshold
represents the difference between the
forward power and the reflected
power (in dBm). A higher value
here represents a configuration that
is more sensitive to VSWR.
Gain (VVA) Level
(Read Only in Run Mode)
Gain: XXX.X%
When the unit is in ALC mode this
value will change dynamically as the

the Output Level Set display.
User can change either VVA or ALC
level by using the  and  keys on
the panel after first pushing the
‘ALC’ or ‘GAIN’ buttons.
