Vertical Calibration for CCIR and NTSC Video Graticules
captive
When the video graticule is installed, the 10 horizontal divisions along
line 0 correspond to the internal graticule divisions, and the TIME/DIV
calibration of the oscilloscope remains unchanged. However, the vertical
divisions represent only proportions of the 100-unit (CCIR) or the 140-unit
(NTSC) video waveform, and the vertical VOLTS/DIV calibration is
inapplicable.
Tb calibrate for a standard 1-volt (nominal) video signal, apply the
300-mV CALIBRATOR square-wave signal to either the CH 1 or CH 2 vertical input
and adjust the associated VOLTS/DIV and VOLTS/DIV VAR controls so that the
displayed waveform occupies either 30 units on the CCIR graticule or 42 units
on the NTSC graticule. This adjustment may be made with a well-focused,
free-running display.
