Alignment
Only one extender board (if optional)
should be installed at a time for access to the
board being aligned. Also, the test equipment
must be thoroughly warmed up before begin-
ning.
Note: Signal levels in dB referred to in
alignment are based on 0 dBp=0.5pV.
Table note: DC voltages should be within
