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.
