] + A
Trigger Level Error + 50 ns.
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 A-SEC/DIV Setting.
LSD

+ [10 ppm x (measured interval)] + TJE + A-Trigger Level
Error + B-Trigger Level Error + 0.5 ns.
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.
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.
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.
