AWG2021 User Manual
NTSC color bar signals, NTSC Y-C separate signals and various kinds of NTSC
signals are stored in the NTSC directory. These are NTSC video signals made up
of 1 – 4 color fields and 1050 lines (525 x 2). The clock frequency is 16 times
the sub-carrier frequency; a waveform is created on each line and the compiled
waveforms are assembled using the sequence editor.
The settings for the signals are described below.
Settings
Waveform points: 1H=3,640
Clock frequency: 57.27 MHz (3.579545 MHz × 16)
Output time: 33.37 ms
Waveform points: 3,822,000
Video signals are output by changing the directory to
NTSC.DIR and then
selecting the following sequence files in the
SETUP menu:
( 1) Color Bar (Composite) signal $CB1-2H.SEQ
( 2) Color Bar (Luminance) signal $CB1-(Y).SEQ
( 3) Color Bar (Chrominance) signal $CB1-(C).SEQ
( 4) Multiburst signal $M-BURST.SEQ
( 5) Modulated Ramp signal $RAMP.SEQ
( 6) Sweep signal (1 10 MHz) $SWEEP10.SEQ
( 7) SMPTE Color Bar signal $SMPTE.SEQ
( 8) IYQB signal $IYQB.SEQ
( 9) Reversed Blue Bar signal $RBLU.SEQ
(10) Color Bar + Reversed Blue Bar + IYQB signal $MIX.SEQ
Figure D-18 through Figure D-26 shows the
NTSC composite video signal.
