Pulser walkthroughs R2 & R3 should be ignored as + polarity test input
had significantly lower amplitude (x2 oor more) than - polarity test input.
The + polarity test input is derived from tee'd output from BNC PB-4 and
EG&G Ortec 433 Sum & Invert - physically moving the cabling and connectors
between these two points changed tail pulse amplitude or produced a transient
(non-tail) pulse with duration ~ 100ns. Not clear which cable or connector
is the issue (all cables and connectors were individually replaced) but output
amplitude currently correct so will proceed.
