IM/HDCU1000 Series
2-5. Video Signal System
The equipment that is used for HDCU1000/1080/1500 and
the HDC1000 series camera system were set to the speci-
fied level when shipped from the factory. Before operating,
check the signal levels between each equipment and adjust
them if required. Some adjustments can be performed
using the maintenance menu of the MSU-900/950 besides
using the control or switches on the board. Perform the
basic adjustments on the board and perform the fine
adjustments on the maintenance menu.
2-5-1. Selecting the Input/Output Signal
Select the input/output terminal signal of the rear panel
according to the video system to be installed.
2-5-2. Adjusting the Signal Phase
Adjust the signal phase of HDCU1000/1080/1500. Before
adjustment, input the following sync signals to the unit and
each of the equipment used.
HDCU1000/1080/1500
REFERENCE
HD ternary SYNC : 0.6 V p-p
or
black burst signal :
40 IRE (0.3 V p-p)
(SMPTE318M (10F-BB) is also acceptable.)
n
When the VBS signal of HKCU1001/1003 is used (when
SC phase lock is required), use the black burst signal.
HKCU1003 (Using VDA-64B)
(HDCU1000/1500 only)
FRAME REFERENCE
HD ternary SYNC : 0.6 V p-p
or
black burst signal :
40 IRE (0.3 V p-p)
sequence pulse :
40 IRE (0.3 V p-p)
Adjusting the Phase of the Sync Signal
Adjust the phase of the output signal to match it with that
of the reference signal. Perform the adjustment using the
switch on the AT-167 and EN-159 board (HKCU1001/
1003) panel of HDCU1000/1080/1500. The adjustment
also can be performed on the maintenance menu of the
MSU-900/950.
How to adjust on the AT-167 board and EN-159A/
159B board (HKCU1001/1003) of the unit
1.
Select the type of external sync signal using the
REFERENCE SIGNAL selector switch on the AT-167
board panel.
HD : HD ternary SYNC
SD :
BB (black burst) signal
REM : Control is performed by MSU, etc,. connected
outside.
Factory setting : REM
2.
When setting HD in step 1 :
1) Coarse-adjust the H phase using H-STEP on page
“S01” of the system menu, then fine-adjust it
using the H PHASE switch on the AT-167 board
panel.
When selecting SD in step 1 :
1) Coarse-adjust the H phase using H-STEP on page
“S01” of the system menu, then fine-adjust it
using the H PHASE switch on the AT-167 board
panel.
2) Adjust the SC phase using switch SC PHASE on
the EN-159A/159B board (HKCU1001/1003)
panel (when the BB signal is selected as a refer-
ence).
