1760 Series Component Waveform/Vector Monitor User Manual 4-1
Basic Measurements
Basic Measurements contains 1760--Serie s graticule de scrip-
tions, followed by specific measurement procedures.
This monitor uses a n int ernal graticule, which combines wa-
veform and vector markings. The internal graticule scales
are on the same plane as the CRT phosphor, eliminating par-
allax errors. Graticule illumination can be adjusted through
the
CRT menu (page 3-27) to provide optimum brightness for
viewing or photographing displays.
Waveform Graticule
There are three versions of the waveform graticule, illus-
trated in Figure 4-1, Figure 4-2, and Figure 4-3:
H NTSC composite video graticule (1760).
H CCIR composite graticule (1761).
H Dual standard graticule (1765).
Horizontal Scale
The 0 IRE (0.3V) graticule line is divided into 12 major divi-
sions. Each division represents a unit of time determined by
the
SWEEP and MAG settings. Line sweep rates are as fol-
lows:
SWEEP
MAG ON
TIME/DIV
1 LINE SWEEP
2 LINE SWEEP
5 µS/D
iv
10 µS/Div
200 nS/Div
1 µS/Div
In
2 FIELD SWEEP with MAG ON, the entire vertical interval
can be viewed.
