When the A Sweep
is
triggered by the Word
Recognizer
in
synchronous mode, add 1 ns for
probe jitter;
in
asynchronous mode, add 20 ns
for probe jitter.
Both
delays are within 70 ns
to
10 times the
A-SEC/DIV setting.

0.5 ns for channel-to-channel

In
Auto Resolution, twice per second
or
once
for every four sweeps, whichever
is
slower.
In
1 ns, 100 ps, and 10 ps resolution modes,
the update rate depends on the A
SEC/DIV
setting and the trigger repetition rate.
cB
Time/Div includes SEC/DIV,
X10
MAG, and VAR.
dThis term assumes the trigger pOints are between the 10% and 90% points
of
the
waveforms.
Fall time is expressed as a negative risetime.
