TJE = Trigger jitter error (seconds).
P = Period of input (seconds)
N = Number of input samples accumulated = F(0.25 second ±0.01 second) > 1 .
LSD = One count in least significant digit.
TBE = Time base error (fractional).
G = Number of gate intervals in one measurement = (A sweep repetition rate) (0.25 second ±0.01 second) > 1 .
Ng = Number of samples inside one gate interval > 1 .
•Performance Requirement not checked in Service Manual.
•Reduces to ± LSD for pulse inputs with transition times < 2 0 ns.
