371B Service Manual
Performance Check and Adjustment Alternative
When you perform the complete set of performance check and adjustment
procedures provided in this chapter, the 371B is thoroughly checked and adjusted
to meet performance characteristics. Tektronix recommends that the complete set
of checks and adjustments be performed after 2,000 hours of operation or at least
once a year.
It is not necessary to perform all the checks and adjustments whenever you make
a minor repair or whenever a specific area of 371B performance is questioned.
The performance check and adjustment procedures are designed to check a
specific electrical specification or to perform a specific adjustment. Thus, in
most cases, you need to perform only those performance check and adjustment
tasks required based on the level of repair made or the scope of electrical
specification(s) in question. Carefully read Table 5–2 to select the appropriate
procedure alternative.
