The HP 4142B Modular DC Source/Monitor is a user-configurable DC parametric tester from Hewlett-Packard with an open architecture mainframe accepting plug-in measurement modules. The mainframe provides eight slots that accept a mix of Source/Monitor Units (SMUs), High Current Units (HCUs), High Voltage Units (HVUs), Voltage Source/Voltage Monitor Units (VS/VMUs), and the Analog Feedback Unit (AFU). The instrument is positioned by HP for DC characterization of semiconductor devices, process control in semiconductor manufacturing, and device modeling in research and development.

Applications listed for the pre-owned HP 4142B include verifying process quality in semiconductor manufacturing, developing sub-micron and high-power technologies, characterizing new materials, and evaluating finished components. Device types named on the datasheet include GaAs FETs and diodes, bipolar transistors, MOS and CMOS structures, power bipolar and MOSFETs, thyristors and SCRs, operational amplifiers, resistive networks, and smart power devices. The pulse capability is presented as a method for reducing thermal drift error and enabling tests on high-power devices, including at the wafer level.

Every {{CONDITION}} HP 4142B sold by ValueTronics is processed through our 20,000 sq ft secure warehouse at 1675 Cambridge Drive, Elgin, Illinois, where our technical team verifies each mainframe and its installed modules before shipment. This in-house handling is the structural difference between a verified instrument from ValueTronics and an unverified marketplace listing — and it is the reason engineers and procurement teams have relied on us as a single source for legacy HP, Agilent, and Keysight parametric test equipment since 1992.

Brand Heritage

Hewlett-Packard's test and measurement division was spun off as Agilent Technologies in 1999, and the electronic measurement business of Agilent became Keysight Technologies in 2014. Instruments originally branded HP — including the 4142B family documented here — are part of the lineage now supported under the Keysight name.

Important: The HP 4142B mainframe allows a maximum of one HP 41425A Analog Feedback Unit per chassis. Total instantaneous output power summed across all installed modules cannot exceed 32 W.
Important: No more than one HP 41425A Analog Feedback Unit per HP 4142B mainframe.
Important: Maximum Common to Ground Voltage: ±42V.
Important: The sum of all measurement units' instantaneous output power cannot exceed 32W per mainframe.
Important: HP 41422A HCU operates in pulse mode only. Pulse is unipolar (voltage and current are the same polarity) and the pulse base value is fixed to 0 volts.
Important: The HP 41423A HVU outputs hazardous high voltages up to ±1000 V. A high voltage triaxial cable, connectors, fixture interlock, and LED status indicator provide hazard protection — use only with the supplied safety interlock.
Important: Plug-in measurement modules (HP 41420A HPSMU, HP 41421B MPSMU, HP 41422A HCU, HP 41423A HVU, HP 41424A VS/VMU, HP 41425A AFU) are ordered separately as mainframe options (Opt. 400–450); the HP 4142B mainframe ships with the Ground Unit and Safety Interlock but plug-in modules must be specified at order.
Important: Test fixtures (HP 16058A, HP 16088B) and module selector (HP 16087A) are not included with the mainframe; the appropriate fixture and cabling for the DUT geometry must be ordered separately. The HP 16087A control module and HP 16088B Opt 300 require the mainframe Opt. 300 Control Unit.
Important: For complete ordering information, including recommended controllers, optional software, cabling, connectors, fixtures, and other accessories, see the HP 4142B Modular DC Source/Monitor configuration guide (HP literature number 5091-0634E).
Recommended pairing: the HP 16088B Test Fixture (with optional Option 300 built-in HP 16087A Module Selector) provides Kelvin connections across all HP 4142B plug-in unit types and is the test fixture HP designed specifically for this mainframe.
