ES-229 & ES-230
NTSC / PAL COLOR BAR GENERATORS
The ES-229 and ES-230 are Color Bar Generators that can be used for aligning monitors or for checking
the signal fidelity of a video system. Both units generate RS-170A full-field bars or black-burst. The ES-229
provides one composite output and one S-Video output while the ES-230 provides eight composite outputs.
Front-panel DIP switches allow selection of Auto-Black, Bars / Black, Interlace / Progressive, NTSC pedestal
On / Off, Chroma On / Off and PAL mode.
If the “Tone” option is ordered on the
ES-229, a 1 KHz tone is output from the rear-mounted RCA connector
and on the ES-230, the frequency can be set to 400 Hz or 1 KHz.

Operation Notes:
The “Auto-Black” mode generates Color Bars (& Tone if ordered) for 30 or 60 seconds after the START
button is pressed, then switches to silent Black-Burst. In “Bars” mode, only color bars are output and in
“Black” mode, only Black-Burst is output. The “Interlace/Progressive” switch allows for either 524/624 Line
Progressive or 525/625 Line Interlace operation and the “Pedestal” switch allows selection between 7.5
IRE Setup or 0 IRE when in NTSC mode (In PAL mode, 0 IRE is output regardless of setting.). Burst is always
present whether the “Bar Chroma” switch is on or off.
