Test Sawtooth

Lens matching

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.

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.

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.

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.

4-2 Technical Manual LDK 20(S) - Studio Camera Adjustments

Test Equipment

Set-up Instructions

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

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.
