up in
45
degree steps.
You
should be able to see the phase
of
the
Channel
B
signal shift on the oscilloscope relative to the Channel
A
signal each time you press the
0
key.
If
you continue to press the
0
key,
you
will find that the
HP
8904A
does not respond to your
45
degree increment at
315
degrees. This is
because the maximum phase shift allowed by the
HP
8904A
is
359.9
degrees.
