Section 1
Performance Check and Calibration Procedures
This section consists of two separate procedures. The first, a Performance
Check, is used to determine compliance with the Performance Requirements in
the Specification. The Performance Check is followed by a Calibration
Procedure, which provides adjustment instructions intended to return the
instrument to its original operating performance following repairs or a routine
maintenance program.
In both procedures, front- and rear-panel controls and connectors for the
instrument under test are fully capitalized (e.g., VARIABLE GAIN). Control
and connector names on test equipment and internal adjustments for the
instrument under test are initial capitalized (e.g., Time/Div, Geometry, etc.).
Limits, tolerances, and waveforms given in this section are guides to adjustments
and checks, and are not instrument specifications unless they are listed as
Performance Requirements in the Specification.
Recommended Equipment List
The following equipment is recommended for use in the Performance Check and
Adjustment Procedures for this instrument. Other equipment may be substituted;
however, care must be used to ensure that the accuracy of the substituted
equipment does not compromise the results of a particular procedure step.
NOTE. Using the equipment in the Recommended Test Equipment list, an
accuracy ratio of 4:1 or better for warranted measurement specifications will be
obtained, with the following exceptions:
Amplitude Accuracy is 2:1
Linearity and Dif Gain are 2.5:1
Diff Phase is 1.6:1

For example: a TEKTRONIX VM700A Opt 1, Opt 11 (Firmware Version
2.6 or later).
