Performance Tests
— Four test cables
Description of the Test:
Figure 3-14 Dynamic Accuracy at Low Frequency Setup
If the Analyzer Fails this Test:
— If the analyzer fails this test, rerun the test.
— If the analyzer fails this test repeatedly, run the DC continuity test. Refer to
“DC Continuity Test the LFE Board and Test Ports (Available with LFE
Option 205/220/420/425)” on page 3-43 and to “Removing and Replacing
the A70 or A75 Low Frequency Extension (LFE) Board” on page 7-59 .
Due to the complexity of the PNA family of analyzers, the following notes
apply to illustrations in the PNA Help:
—
Only a single representative model will be shown.
— Some illustrations may differ than those in TME.
— If the test procedure applies to multiple ports, illustrations will show
the setup on only one test port.
—
Setups for some option configurations may not appear in the Help.
For the two cables between the power splitter and attenuators, choose
short but flexible cables.
