MANUAL

 CHANGE

 INFORMATION

At Tektronix, 

we continually strive to keep up with latest electronic 

developments 

by adding circuit and 

component improvements to our 

instruments 

as soon as they 

are

 developed and tested.

Sometimes,

 due to

 printing and shipping requirements, we can’t get these 

changes

 immediately into printed manuals. Hence, your manual may contain new 

change information

 on following pages.

single change may affect several sections. Since the change information sheets 

are

 carried in the manual until all changes are permanently entered, some 

duplication may 

occur. If

 no such change pages appear following this

 page, your 

manual is

 correct as printed.

SERVICE 

NOTE

Because of the universal parts procurement problem, some electrical parts 

in your 

instrument

 may

 

be different from those described in the Replaceable Electrical Parts 

List.

 

The parts

 used will 

in no

 

way alter or compromise the performance or reliability 

of this

 instrument. They are installed when necessary to ensure prompt delivery to 

the customer. 

Order replacement

 parts from the Replaceable Electrical Parts List.
