This page was generated automatically from cited public sources and hasn't completed the full research pass yet. Every specification shown carries its source; more detail is added as research completes.
What it is
The Agilent 85407 A is an S-Parameter Test Set.[1]
How it works
General reference — not yet source-verifiedAn S-parameter test set contains internal switches and directional couplers that route the stimulus signal from the network analyzer to the device under test and direct the reflected and transmitted signals to the analyzer's receivers.
The test set allows measurement of forward and reverse transmission and reflection coefficients without manually reconnecting cables.
Where it fits in the process flow
General reference — not yet source-verifiedS-parameter test sets are used in laboratory and production test environments for characterizing the radio-frequency performance of discrete devices, modules, and integrated circuits.
In semiconductor manufacturing, such test sets are employed during final test or in process control monitoring of radio-frequency components, often in conjunction with a probe station or a test fixture.
Applications
General reference — not yet source-verifiedApplications include device characterization, design verification, and production testing of components operating in the radio-frequency and microwave spectrum.
