G — Number of gate intervals in one measurement = (A sweep repetition rate) (0.2S second ±0.01 second) > 1 .
TJE = Trigger jitter error (seconds).
N = Number of input samples accumulated = F(0.25 second ±0.01 second) 5*1.
TBE = Time base error (fractional).
TA = Delta time being measured in seconds.
en1 ~ RMS noise of vertical system (in divisions on screen).
en2 = RMS noise voltage of input signal (in divisions on screen).
■Performance Requirement not checked in Service Manual.
'Reduces to ± io nsec for pulse inputs with transition times < 2 0 ns.
