In Topic: CE2000 bias -- error in service manual ?

10 July 2013 - 11:13 AM

Agreed, thanks, that's why I asked. Bias is developed across BE junction - below cutin for outputs.
Same measurement in the DC300 series. Schematics and board layouts for CE contradict the service manual.

With no load/no signal, if DC offsets are small enough (~0 mV) then which output is used should not really matter, provided
that measurement causes no appreciable current flow (which should be the case with high impedance DVM) - because there
is no current flow through the emitter leg to output (ie., outputs are not on, no IR drop across 0.2ohm).
