Cathode ray tubes
Components marked
on the circuit diagram are critical
for safety and include those specified to comply with X-ray
emission standards for units using cathode ray tubes and
those specified for compliance with various regulations
regarding spurious radiation emission.
When servicing units that use cathode ray tubes (CRTs),
the cathode ray tubes themselves, the high voltage circuits
and related circuits are specifically chosen so that they
comply with recognized codes pertaining to X-ray emission.
Consequently, when servicing, replace the cathode ray
tubes and other parts with specified parts only. Do not
attempt to modify these circuits as any unauthorized
modification can increase the high voltage value and
cause X-ray emission from the cathode ray tube.
Handle the cathode ray tube only when wearing shatterproof
goggles and after discharging the high voltage completely.
Earthing
The rear of a CPU has two separate screw terminals for
protective earth (PE) and video earth (VE).
These are normally connected by a metal strap. The
protective earth terminal is internally connected to the
protective earth conductor of the power cable. If required,
the central earth connection wire of the studio can be
connected to terminal PE.
In normal circumstances the connection between the
protective earth and the video earth should not be broken.
The metal strap may be removed only if the studio (or OB
van) is equipped with separate protective and video earth
systems. Under these circumstances the video earth
terminal must be connected to the central functional earth
potential (video earth) of the studio. This earth potential
should have functional protective and noiseless earth
(FPE) qualities as stated in the VDE regulation 0800/part2.
A low impedance interconnection of both earth conductors
must be provided at the central studio earthing point.
WARNING
THE UNIT MUST ALWAYS BE CONNECTED TO
PROTECTIVE EARTH.

Lens matching
When a camera is supplied with a lens it is not
necessary to perform any of the following adjustments
as the lens is already matched to the camera. However,
if you wish to change to a different type of lens or the
lens is not supplied with your camera, back focus,
white shading and auto iris adjustment procedures
may have to be performed.
• Colour balance.
If required, perform the gain adjustment of the
preprocessor board and/or white shading adjustment
procedures, described in section 4.
• Auto Iris Adjustment
If a different lens either works too slow or overshoots
too much with the auto iris control, adjust the
potentiometer on the lens to obtain acceptable
operation. Refer to the lens documentation.
• Back Focus Adjustment
To adjust the back focus of the lens refer to the
documentation of the lens.
Test Sawtooth
A test sawtooth signal is normally only used for
adjustment procedures. Jumper X3 on Video processor
1 board provides a choice between two internal signals
or an external signal.
Internal signals
Set jumper X3 to position BC to get the nominal
sawtooth. This is used for checking amplitudes.
Set jumper X3 to position AB to get a small sawtooth
(approximately 25% nom.). This small sawtooth is
used for checking painting or colour temperature
ranges.
External signal
To inject an external test signal first set jumper X3 to
position CD (test input). Connect the external test
signal to connector X4-1/2. The nominal value of this
signal is 700 mV without sync.
The test sawtooth signal is switched on by means of
the Operate menu of the camera or the Setup 1 menu
of the MCP.

Private Data
Private data channels can be used for the transmission
of serial data via the triax cable. For example, electronic
scriptboard or character data for a video display unit
can be transmitted to the camera.
The tracker microphone intercom channel is used for
the data channel from camera head to base station.
The program intercom channel is used for the data
channel from base station to camera head. The input
and output signals are available on the auxiliary
connectors of the camera and base station (for camera
see the connectors and cables section). If a channel
is used for private data, then of course the original
functions are no longer available.
To select the function of the base station to camera
channel use S801 on the Audio/intercom board. Position
AB selects the Progr function (factory setting); position
AC selects the private data function.
To select the function of the camera to base station
channel use S802 on the Audio/intercom board. Position
AB selects the tracker microphone function (factory
setting); position AC selects the private data function.
Remember that the propagation-delay times are different
for different triax cable lengths, especially if a return
signal is involved. At maximum lengths of 2400
metres the total delay is at least 25 µsec. and can be
more than 30 µsec, depending on the type of triax
cable.
Data signal specifications:
Baudrate: 2400
Input level: TLL, possible RS232
Input impedance: 100Kohm
Output impedance: ~300 ohm

4-2 Technical Manual LDK 20(S) - Studio Camera Adjustments
Introduction
This camera is factory tested and adjusted for operational
use. Under normal circumstances, the internal
potentiometers do not need to be adjusted.
If it is discovered that the camera is misaligned, the
following procedures are given as a guide for competent
service personnel, who have a thorough knowledge of
the camera and have the use of calibrated equipment,
to realign the camera.
If no improvement can be achieved or an adjustment is
out of range, please contact your local supplier or the
nearest Thomson Multimedia Broadcast Solutions
Service Centre.
The camera head adjustment procedures are designed
as separate units. Within a numbered procedure do not
change the position of switches or jumpers unless
instructed to do so in the procedure.
These adjustment procedures are for the Camera Head.
The adjustments require the use of a Master Control
Panel in combination with an Operational Control
Panel if possible. The intercom adjustments are given
for a four-wire system.
Page 29
Adjustments Technical Manual LDK 20(S) - Studio Camera 4-3
Test Equipment
The following is a list of equipment required to carry out
the adjustment procedure:
• Set of board extenders LDK 4830/21
• Oscilloscope (with cursor measurement)
• Spotlight 3200K
• Gamma Test chart 4:3 / 16:9
• Waveform monitor
• Colour monitor
• Multimeter
• Master Control Panel LDK 4607 / LDK 4609
• Operational Control Panel LDK 4624 / LDK 4628 /
LDK 4629
• Audio Analyser
• Base Station LDK 4053
Set-up Instructions
Before carrying out any adjustments the following steps
are recommended:
• Install the camera on a tripod.
• Attach the lens and the necessary cables.
• Allow the camera to warm-up.
• Operate the camera in stand-alone mode
• Connect an MCP and OCP to the data connector on
the right connector panel of the camera.
• When the camera is used in the stand-alone mode,
MCP and OCP always operate in camera select
position 1 (OCP camera select switch in position 1).
CAUTION:
Do not attempt to improve camera performance
by adjusting individual potentiometers, jumpers or switches
as this may lead to complete misalignment of the camera.
CAUTION:
Do not realign individual potentiometers, jumpers or switches
not mentioned in this chapter or earlier in this manual.
These adjustment points are for factory use only.
CAUTION:
Switch off the power supply to the camera
before removing or replacing printed circuit boards.
