Menu assistant manual
1. The original RF Mode =AGC, the OMI menu displays RF Mode= ;
at this time. If you press "SELECT", display RF Mode= ;
Press "▲"or "▼", the menu display: RF Mode=Manual.
2. If display "INTERLOCK", and Red blinking light, it may be the
remote point at the back panel is loose.
3. If RF input level is too high, there will be alarm and Red blinking
indicator, shut down the power supply and turn on again.
4. +5V voltage (+5V READS) >±0.5V alarm.
-5V voltage (-5V READS) >±0.5V alarm.
5. If a fault has occurred, there will be an alarm (Red blinking),
Microprocessor will shut down the laser automatically, and digital
panel will show the cause of the fault.
PRODUCT FEATURE
1. Dual Module RF drive, high efficiency laser pre-distortion adjustment.
2. Full-automatically optical Modulation Intensity (OMI) control,
AGC&MGC.
Under AGC select, input range is 18dBmV~28dBmV, system index is
optimum.
Under MGC select, RF input range can be adjusted 15dBmV~30dBmV
by the ATT on front panel.
3. Front panel has 20 lines OMI select display (Modulation Depth).
Under AGC select, within RF range, OMI is always at NOM select.
Under MGC select, OMI can be at NOM select by adjusting ATT.
4. Dual power supply built-n backup. Full-automatic switching.
One is on and working, the other set to off as a cool backup
(suggested).
When both are on at the same time, one acts as hot backup. If one is
damaged, switching to the other is fully automatic. Switch
time≤10us.
5. Full-automatically control of casing temperature, ensures long life of
the laser.
Casing temperature is monitored and controlled by micro-processor.
Display screen shows the actual operation temperature in time.
When casing temperature≥45°C, Two fans at the back panel will
switch on automatically to cool it by constraint.
When casing temperature≤35°C, the fans will shut down
automatically to ensure longer life of the fans.
