Requirements
RGB/YRGB
Staircase Input
Amplitude A +10 V input will result in a
horizontal display of 9 divisions
±1.4 major divisions.
Ground to +10 V. +10 V
corresponds to left side of
the CRT.
Staircase Operating
Signal DC Signal levels plus peak AC,
not to exceed –12 to +12 volts.
Max AC signal volts 12 V peak-to-peak. Field or line rate sweeps.
Sweep Length
RGB 2 Field = 27 – 33% of nor-
mal. 1 Line = 27 – 33% of
normal. 2 Line = 27 – 33%
of normal.
YRGB 2 Field = 20 – 25% of nor-
mal. 1 Line = 20 – 25% of
normal. 2 Line = 20 – 25%
of normal.
Sweep Repetition
Rate Field or line rate of displayed
video or external sync signal as
selected by front-panel HOR-
IZONTAL controls.
Requires 1H or 1Fld sweep
selection.
External Horizontal Input Used for ICPM measure-
ments.
Sensitivity Direct coupled 0 – 5 V.
Sawtooth input of up to 5 V
is nominally a 10 division
horizontal sweep.
Input Impedance ≈10 kW.
