Monitor the pin 21 east/west output (parabola
waveform output) and measure the voltage at the
22nd line under the conditions with COR
TOP
set to
111 and to 000. Let Va and Vb be these
measurements. Calculate the following formula.
EWcortop = Va – Vb
Monitor the pin 21 east/west output (parabola
waveform output) and measure the voltage at the
262nd line under the conditions with COR
BOT
set to
111 and to 000. Let Va and Vb be these
measurements. Calculate the following formula.
EWcorbot = Va – Vb
Measure the pin 29 output burst gate pulse peak
value.
Measure the delay time from the rise of the
horizontal synchronizing signal to the rise of the pin
29 burst gate pulse.
Measure the width of the pin 29 burst gate pulse.
