Dual-Standard Vertical Scale
The dual-standard graticule combines the NTSC and PAL
scales. The NTSC scale is on the left side; the PAL scale is
on the right. The divisions represent 10 IRE in amplitude (70
mV for PAL). The instrument gain is automatically adjusted
for the particular standard used. On-screen arrows point to
the graticule scale (left side or right side) that is calibrated
for the present operating mode.
