Accuracy Resolution Error ± (TBE)TA.
G = Number of gate intervals in one measurement =
(A
sweep repetition rate) (0.25 second ±0 .0 1 second) > 1 .
TBE = Time base error (fractional).
Td = Delay time being measured in seconds.
TJE = Trigger jitter error (seconds).
TA = Delta time being measured in seconds.
■Performance Requirement not checked in Service Manual.
'Reduces to ± io nsec for pulse inputs with transition times < 2 0 ns.
