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.

If CH 3 or CH 4 is one channel of a two-channel measurement, add
0.5 ns for channel-to-channel delay mismatch.

for trigger offset.
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.
b
See Tables 1-3 and 1-4.
C
B Time/Div includes SEC/DIV, X10 MAG, and VAR.
d
This term assumes the trigger points are between the 10% and 90% points of the waveforms. Fall time is expressed as a negative
risetime.
