Removal and Installation
Acquisition System The Acquisition system consists of the Time Base circuit board and bracket, the
Electrical Front-End circuit board and chassis, and the Optical Front-End circuit
board and chassis. The circuit boards are not customer replaceable.
If any of these circuit boards must be replaced, return the instrument to Tektronix
for repair. However, you can remove the assemblies temporarily, to gain access to
cables or mechanical parts that are customer-replaceable. Refer to the Replaceable
Parts list to
fi nd part numbers of replaceable parts.
Removing a circuit board assembly to gain access to mechanical parts and then
reinstalling the same circuit board assembly should not affect the board calibration
if you are careful not to loosen or damage any parts.
CAUTION.
Use care not to loosen or damage any parts. This could disrupt
instrument operation and calibration.
Before removing the assembly, be sure that this will not affect your product
warranty.
