Performance
Tests
This subsection contains procedures to verify that the
TAS
475 and
TAS
485
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 Perfor-
mance Checks
in
this section .
•
The tests
in
this subsection comprise an extensive, valid confirma-
tion of performance and
functionality when the following require-
ments are met.
• The cabinet must be installed on the oscilloscope.
• The Power-On Self
Tests
show no failures .
•
You
must have completed the Temperature Compensation Calibrations,
beginning on page 4-9.
• The oscilloscope must have
an
operating warm-up period of at least
20
minutes at
an
ambient temperature between
-10
0
C and +55
0
C.
• Set the INTENSITY and READOUT controls for nominal viewing levels.
• Set
the delayed sweep intensity to Intensity
Delay>
Main
in
the Utility
Configure menu.
Related Information - Read General Instructions that start on page 4-1.
If you are not familiar with operating this oscilloscope, read Section
NO
TAG,
Getting Started, before performing these procedures.
These procedures use
external, traceable signal sources to directly check
warranted characteristics. Table
4-1
lists the required test equipment.
