SMA-8018 Serial Monitoring Amplifier
1-4
V BLANK (JP2)
NORMAL
Deletes all vertical interval information signals
(20-line blanking).
SHORT
Passes all vertical interval signals occurring after the
post equalizing pulses. If setup is ON, the signal will
be non-standard because setup will be applied to the
vertical interval.
SETUP (JP2)
ON
For NTSC in North America
OFF
For all other systems
MODE (JP2)
NORMAL
Normal operation
TEST
Produces an analog color bar output. This may be
useful for monitor alignment.
OUT 7 (JP3) D
Output 7 will have a serial digital output.
A
Output 7 will have a composite analog output.
FAULT REPORT (JP1)
DISABLE
SMPTE 269M Fault Report is disabled.
ENABLE
SMPTE 269M Fault Report is enabled.
3)
Final User Setup
Set the analog output EQUALIZATION (RV2) adjustment for the cable length used between the
amplifier and destination. Plug the board into the frame and apply power.
The equalization control is calibrated for 8281 cable. For other types of cable, put the board on
the extender, apply a D1 color bar signal and using a scope, set the EQUALIZATION adjustment
for correct chroma level at the destination.
4)
Check that the green INPUT STATUS LED is on and the MONITOR ERROR LED is off,
indicating a suitable input signal. The amplifier should be functioning properly.
