Tektronix TPG20 Section 1 Performance Check and Calibration Procedures

TPG20 Service 1–1

Section 1Performance 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.

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
