Description
0.75 divisions of composite sync will achieve a stable display.
Stable
video trigger with up to 4 divisions of 60 Hz on the video
signal.
Stable
video trigger if sync tip is ± 15 divisions, referenced to input
ground.
Stable trigger on positive or negative composite horizontal sync
(lines) video, for all 525/60 and 625/50 video systems which include:
NTSC,
PAL, and SECAM.

Absolute Volts Accuracy
AVolts Cursor to Signal Accuracy
Description
Same as Time Base Accuracy + 0.1 division.
Readouts
calculated using ~ Time cursor difference.
Accuracies are as
follows:
Condition Accuracy
± (1 % of reading + 2% of one vertical
division + HF display errors + 0.5 mV +
trace shift errors).
± (1 % of reading + 2% of one vertical
division + HF display errors + 4 mV +
trace shift errors).
± (1.6% of reading + 2% of one vertical division + HF display
errors).
