Performance Tests
This subsection contains procedures to verify that the TAS 455 and TAS 465
Analog Oscilloscopes perform as warranted.
The procedures are arranged in three logical groupings: Vertical Checks,
Horizontal Checks, and Trigger Checks. They check all the characteristics
that are designated as checked in Section 1, Specifications. (The checked
characteristics appear in boldface type under Warranted Characteristics in
Section 1.)
These procedures extend the confidence level provided by the Brief PerforĆ
mance Checks in this section.
The tests in this subsection comprise an extensive, valid confirmaĆ
tion of performance and functionality when the following requireĆ
ments are met:
H The cabinet must be installed on the oscilloscope.
H The PowerĆOn Self Tests show no failures.
H You must have completed the Temperature Compensation Calibrations,
beginning on page 4Ć9.
H The oscilloscope must have an operating warmĆup period of at least
20 minutes at an ambient temperature between -10_ C and +55_ C.
H Set the INTENSITY and READOUT controls for nominal viewing levels.
H Set the delayed sweep intensity to Intensity Delay > Main in the Utility
Configure menu.
Related Information Ċ Read General Instructions that start on page 4Ć1.
If you are not familiar with operating this oscilloscope, read Quick Start in
Section 2 before performing these procedures.
These procedures use external, traceable signal sources to directly check
warranted characteristics. Table 4Ć1 lists the required test equipment.
