2.4.4 Selecting the Horizontal Magnification
To select the horizontal magnification, follow the procedure below. The magnifications that
you can select vary as shown below depending on settings such as COLOR MATRIX.
Reference COLOR MATRIX → section 2.7.1, “Selecting the Color Matrix.”
Table 2-1 Horizontal magnifications
F•1 SWEEP COLOR MATRIX F•2 H SWEEP X1 X10 X20 X40 ACTIVE BLANK
H YCbCr, XYZ,
GBR, RGB 1H Yes Yes Yes No Yes Yes
2H Yes Yes Yes No No Yes
COMPOSIT - Yes Yes Yes No Yes No
V - - Yes No Yes Yes No No
(Yes: Settable. No: Not settable.)
Procedure
WFM → F•3 SWEEP → F•3 SWEEP MAG: X1 / X10 / X20 / X40 / ACTIVE / BLANK
Settings
X1: The video signal waveforms are displayed so that they fit on the screen.
X10: The video signal waveforms are magnified from the center of the display to 10
times the size of X1.
X20: The video signal waveforms are magnified from the center of the display to 20
times the size of X1.
X40: The video signal waveforms are magnified from the center of the display to 40
times the size of X1.
ACTIVE: Everything but the video signal waveform blanking interval is magnified.
BLANK: The video signal waveform blanking interval is magnified.
The vertical blanking interval is also displayed on the vector waveform display.
SWEEP MAG = X1
