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 Keysight Agilent 4142 B is a DC supply mainframe. The Keysight Agilent 4142 B can be configured with HP 41421B and 41420A source monitor units.[1]
How it works
General reference — not yet source-verifiedA DC supply mainframe of this class provides the chassis, control, and interconnect functions for installed source and measurement modules. A source monitor unit in this class typically operates by applying programmed electrical stimulus to terminals on a device under test while measuring resulting current or voltage.
Where it fits in the process flow
General reference — not yet source-verifiedTest and probe instrumentation of this class is used around electrical characterization steps rather than material deposition or pattern transfer steps. Such equipment is typically used when engineers need controlled DC bias and measurement during device evaluation, parametric checking, or laboratory analysis of wafers and discrete structures.
Applications
General reference — not yet source-verifiedDC supply mainframes with source monitor units are used for semiconductor device characterization, parametric measurement, and bench or probe station electrical testing. Such systems are commonly applied to current voltage sweeps, leakage evaluation, contact behavior studies, and biasing of structures during engineering analysis.
