* Switching the bias links
Before removing any cover the unit must be switched off and
the power lead removed. The two PCB links may be found by removing
the top cover. The small red link plugs are situated close to
the point where the SHV output connectors on the rear panel are
connected back onto the pulse output board. (These SHV connectors
are linked back to the PCB by semi-rigid cables ending in BNC
circuit board connectors and the links are close to these two
circuit board BNC connectors.) The small red links should removed,
rotated by 90° and replaced for external bias operation.
The orientation of the links for DC coupling (no external
bias) is front-back. The orientation for AC coupling with external
bias is left-right.
The maximum external bias input is +/-1000V.
