Setting control options
Select the control method with the DIL switch as follows:
Lever Label Description
1
Y
Up selects an RGB input, down selects a YUV input
2
XSY
Up selects sync input on Y/Green, down selects sync on the external input
3
VBI
Up for normal blanking, down unblanks lines 6 to 22 and 319 to 335 in 625
standard and lines 10 to 20 and 273 to 282 in 525 standard
4
ST
Down compensates for setup on incoming Y signal.
Only applies to 525 standard. Removes 7.5 IRE of setup on Y input, and
increases the Y gain as required
5
BET
Up selects normal chrominance input levels, down selects ‘Betacam’ levels
6
Tpat
Up selects incoming video, down selects internal pattern or incoming
video/internal pattern split-screen. Select pattern with Adj/Sel rotary control
7
Hpos*
Down allows adjustment of horizontal picture position up to +/- 2uS from
reference sync input. Adjusted by Adj/Sel control.
Note: Hpos fine rotary control is always active and can adjust hozizontal
picture position by +/- 100 ns
8
Y/C
Down allows adjustment of Y to Cb/Cr delay timing. Adjust luminance to
chrominance delay using Adl/Sel. Range is +/- 100ns in approximately 9ns
steps. Switch Cal (lever 9) down then up again to recall factory default
setting of 0ns.
9
Cal
Normally Up. Switch down then up again to force horizontal picture position
and Y to Cb/Cr delay to their default factory settings. Only applies in local
mode and when Hpos and Y/C levers are down.
10
Rmt
Up local board edge control (local mode )
Down remote control by active front panel (remote mode )
Notes:
The Hpos fine (+/- 100 ns) adjustment is available in either local or remote mode.
Betacam chroma levels are intended for use with 625/525 YUV inputs only
Chroma level adjustment is not available with the ADC104FK
The Y control selects between Y and G with the ADC104FK
The Tpat patterns are not available with ADC104N converter.
