O/L indicator
Limiter insert
Trimmers
All jumper link information is printed on the PCB. The threshold for the O/L indicator is
marked next to jumper P3.
The optional limiter inserts, P1 and P2 must both always have jumpers fitted across pins 3/4
and 5/6. The limiter is not available as an option, the jumpers provide for future
development.
Trimmers are provided to optimise the Mid Band and HF common mode rejection ratio
(CMRR). These are factory calibrated and should not be adjusted without special test
equipment.
