Performance Verification
Two types of Performance Verification procedures can be performed on this
product: Brief Pr ocedures and Performance Tests. You may not need to perform
all of these procedures, depending on what you want to accomplish.
H To rapidly confirm that the instrument functions and was adjusted properly,
just do the brief procedures under Self Tests, which begin on page 4--5.
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 instrument 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 brief procedures under Functional Tests that begin on page 4--6.
Advantages. These procedures require minimal additional time to perform,
require no additional equipment other than a BNC cable and BNC-to-SMA
adapter or a TCA-BNC adapter, and these procedures more completely test
the internal hardware of the instrument. They can be used to quickly
determine if the instrument 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--17, after doing the Functional and Self Tests
mentioned above.
Advantages. These procedures add direct checking of the warranted
specifications that are marked with the n symbol. These procedures require
specific test equipment. (See Table 4--2: Test equipment on page 4--18).
