Basic Measurements
Basic Measurements cont ains 1760--Series graticule de scrip-
tions, followedby specific measurement procedures.
This monitor uses an internal grati cule, which combines wa-
veform and vector markings. The internal graticule scales
are on the same plane as the CRT phosphor,e liminatingpar-
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 versionsof the waveform graticule, illus-
trated in Figure 4-1, Figure 4-2, and Figure 4-3:
HNTSC composite video graticule (1760).
HCCIR composite graticule (1761).
HDual standard graticule (1765).

Horizontal Scale

The 0 IRE (0.3V)graticule line is divided into 12 major divi-
sions. Eachdivision represents a unit of time determinedby
the SWEEP and MAG settings. Linesweep rates are as fol-
lows:
SWEEP MAG ON
TIME/DIV
1 LINE SWEEP
2 LINE SWEEP
5µS/Div
10 µS/Div
200 nS/Div
1µS/Div
In 2 FIELD SWEEP with MAG ON,the entire vertical interval
can be viewed.
