Performance Verification
The procedures in this chapter verify that the TDS 340A, TDS 360, and
TDS 380 oscilloscopes meet warranted specifications. There are three perfor-
mance tests that you can do.
To rapidly confirm that this oscilloscope functions, do the Self Test
procedures that begin on page 4–5.
Advantages: This procedure is quick to do, requires no external equipment
or signal sources, and performs extensive functional and accuracy testing to
provide high confidence that the oscilloscope performs properly. You can use
it as a quick check before making a series of important measurements.
To further check functionality, do the Functional Test procedures that begin
on page 4–7.
Advantages: These procedures require minimal additional time to perform,
require no additional equipment other than a standard-accessory probe, and
more completely test the internal hardware of this oscilloscope. You can use
them to quickly determine if the oscilloscope is suitable for putting into
service, such as when it is first received.
If you need a more extensive confirmation of performance, do the
Performance Tests that begin on page 4–11, after doing the functional and
self tests.
Advantages: These procedures check warranted specifications. They require
more time and suitable test equipment. (See Test Equipment on page 4–3.)
