Technical Manual LDK 5411 - Betacam SP Adapter Adjustments
Introduction
This unit is factory tested and adjusted for operational
use. Under normal circumstances, the internal automatic
calibration procedures do not need to be started and the
internal potentiometers do not need to be adjusted.
The only situation that might require some realignment
of the adapter is when a printed circuit board has been
replaced.
If the Encoder board is replaced, follow the procedure
for its readjustment. The encoder timing adjustments
can be carried out via the menu system.
If it is discovered that the unit 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 unit.
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 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 Betacam
Adapter.
However, for practical purposes the Betacam Adapter
is used together with the camera head to facilitate some
measurements.
