HORITA CSG-50, User Manual, Page: 9 / 11

a. Select the SMPTE color bar pattern from the CSG-50
b. Connect the waveform monitor to Video Out and set it to observe 2H lines with the DC restorer set to ON, and the
blanking level positioned to 0 IRE.
c. Adjust R11 AMP for a video level of 1 volt p-p (140 IRE), ±1.4 IRE (1%) as measured from the -40 IRE sync tip level
to the 100 IRE white level.
d. Switch to the vector scope and adjust C37 EQ to place the chroma vectors at the centers of the targets. If only a
waveform monitor is available, adjust C37 so the tops of the yellow and cyan chroma levels (next to the SMPTE 100
IRE white level) are also at 100 IRE.
5.6 Audio Tone Amplitude
a. Connect the voltmeter to the 1KHz 0dB output and set it to measure AC RMS volts.
b. Adjust R23 for a reading of 776mV RMS (2.19V p-p), ±7.8mV (1%).
