The Self Tests use internal routines to confirm basic functionality and proper
adjustment. No test equipment is required to do these test procedures.
The Functional Tests utilize the probe compensation output at the front panel
as a test signal source for further verifying that the oscilloscope functions
properly. A standard accessory probe, included with this oscilloscope, is the
only equipment required.
Besides the Brief Procedures, the set of procedures that can be used to verify
oscilloscope performance includes the Performance Tests, found later in this
section. You may not need to perform all of these procedures, depending on
what you want to accomplish:
H To rapidly confirm that this oscilloscope functions and was adjusted
properly, just do the procedures under Self Tests, which begin on
page 4 4.
Advantages: These procedures are quick to do, require no external
equipment or signal sources, and perform extensive functional and
accuracy testing to provide high confidence that the oscilloscope will
perform properly. They can be used as a quick check before making a
series of important measurements.
H To further check functionality, first do the Self Tests just mentioned; then
do the procedures under Functional Tests that begin on page 4 6.
Advantages: These procedures require minimal additional time to per
form, require no additional equipment other than a standard accessory
probe, and more completely test the internal hardware of this oscillo
scope. They can be used to quickly determine if the oscilloscope is
suitable for putting into service, such as when it is first received.
H If more extensive confirmation of performance is desired, do the Perform
ance Tests, beginning on page 4 15, after doing the Functional and Self
Tests just referenced.
Advantages: These procedures add direct checking of warranted specifi
cations. They require more time to perform and suitable test equipment is
required. (See Equipment Required on page 4 16.)
If you are not familiar with operating this oscilloscope, read the TDS 520A,
524A, 540A, 544A, & 644A Reference or the TDS 520A, 524A, 540A, & 544A
