4.4.10 PM GAIN ADJ
INITIALIZE -> 4: INSTALLATION -> 0
The performance monitor function allows checking for the reduction of transmission
output, and reception sensitivity. Make adjustment of PM GAIN ADJ at the time of
installing, and when Magnetron or RF unit is replaced.
1. Procedure for adjustment
1. Select “[INITIALIZE] -> [INSTALLATION] -> 0. PM GAIN ADJ”
Note: When “ 0. PM GAIN ADJ” is selected, the following items are
automatically set up.
- RANGE: 24 NM - AUTO FTC: OFF - BLIND SECTOR: OFF
- PULSE: LONG - IR: 2 - TUNE: AUTO
- ES: OFF - STC: 0 （STC VR Disabled）
- EAV: OFF - FTC: 0 （FTC VR Disabled）
2. Adjust [GAIN] VR so as to allow a small amount of noise. The gain at that time is
approximately “70”.
3. Adjust the PM gain by rotaging the wheel of the track ball so as to allow a slight
amount of the second ring. Numerical input (0 to 255) from the keyboard can also be
accepted for the PM GAIN. “255” is the maximum attenuation level (i.e. lowest
video input levels.)
