Functional Testing
Getting Started
Getting Started
Before You Start
You must do the following before starting functional tests:
1. Ensure you have the proper test equipment, refer to Table 5-1 on
page 142 .
2. Switch on the unit under test (UUT) and let it warm up in
accordance with warm-up requirements in the instrument
specifications.
3. Ensure that the frequency reference is set to internal. To check this,
press
System
and
Reference
. The
Ref Oscillator
softkey should have
Int underlined. If not, press
Ref Oscillator
until Int is underlined.
Test Equipment
Table 5-1 on page 142 summarizes the equipment required to run the
Functional tests. Some tests, like Flatness, can use various model
numbers of a particular equipment type. The “Recommended
HP/Agilent Model” will provide the best results. However, the
“Alternative HP/Agilent Model” is an acceptable substitute. If neither
the recommended nor the alternative test equipment are available, you
may use substitute equipment that meets or exceeds the critical
specifications listed in the table.
NOTE
The validity of functional test measurements depends, in part, on the
measurement accuracy of the required test equipment used. Verify the
proper calibration of all test equipment before running these tests.
Test Equipment Warmup
Allow sufficient warm-up time for test equipment. Refer to their
individual operating or service manuals for warm-up specifications.
Equipment Connections
Test setups for each test are included with the test. These are in the
section titled
“Test Descriptions” on page 143 .
