When the A Sweep is triggered by the Word
Recognizer in synchronous mode, add 100 ns
for probe delay; in asynchronous mode, add
200 ns for probe delay.
For intervals within 70 ns to 10 times the

if the A and B Sweeps are triggered from
different channels, add 0.5 ns for channel-to-
channel mismatch.
When the A Sweep is triggered by the Word
Recognizer in synchronous mode, add 100 ns
for probe delay; in asynchronous mode, add
200 ns for probe delay.
«70 ns.
Display Update Rate In Auto Resolution, twice per second or once
for every sweep, 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.
