5.9.4. ELECTRICAL TEST
The electrical test function creates a current, which substitutes the PMT signal, and
feeds it into the preamplifier board. This signal is generated by circuitry on the pre-
amplifier board itself and tests the filtering and amplification functions of that assembly
along with the A/D converter on the motherboard. It does not test the PMT itself. (See
also Section
12.5.7.2).
