Agilent 8753ET System Verification and Performance Tests
5. Reflection Test Port Output Power Linearity
(Analyzers with Option 004)
This test verifies the analyzer’s test port output power linearity throughout the analyzer’s
frequency range. A power meter calibration sets the reference output power across the
analyzer’s frequency range. The network analyzer’s B-channel receiver is used to
determine power linearity after each change in output power.
NOTE This test does not verify the functionality of the step attenuator. To verify its
function, perform “Step 2. Operator's Check” on page 4-6.
Analyzer warm-up time: 30 minutes
