M9186A PXI Voltage/Current Souce

Data Sheets

Data Sheet

The Keysight Technologies M9186A is a large range, isolated, single-channel voltage-current source providing accurate power supply, making it ideal for automated test equipment (ATE) in automotive electronic applications.

Product Description

The M9186A is a two-slot, PXI based V/I source module that enables the sourcing of a voltage or a current to perform measurements on the resultant current or voltage through another module.

It consists of two separate amplifiers, denoted by “low” and “high” that share a common output connection. The “low” amplifier provides voltages in the range of 16 volts at up to 200 mA and the “high” amplifier provides voltages in the range of 100 V at up to 20 mA.

Typical applications for the low-voltage amplifier include I/O pin parametric leakage, bias current, impedance, threshold and clamp voltage. The high voltage amplifier can be applied to help verify the presence of clamp diodes as the outputs of modules that drive inductive loads. Both the amplifiers can sense the amount of current flowing while forcing a constant voltage.

Uniquely present is a safety interlock for the high-voltage amplifier that automatically disables the high-voltage amplifier and opens all relays when the interlock circuit is broken.

This provides protection to the DUT when dangerous high levels of voltage maybe present. The interlock in indicated by an LED on the module front panel and can be used, for example, by connecting to an external limit switch on fixtures.

Hardware Platform

Compliance

The M9186A is PXI compliant, using either a cPCI, PXI-1 or PXI Hybrid slot. The products can be integrated with other test and automation modules in cPCI, PXI-1 and PXI-H chassis (hybrid slots). The PXI format offers high performance in a small, rugged package.

It is an ideal deployment platform for many automated test systems. A wide array of complementary PXI products are currently available. Products include multimeters, waveform generators, local oscillators, digitizers, downconverters and switch multiplexers.

Range

The M9186A has one of the largest PXI based voltage current range from –10 to 100 V at 20 mA for high voltage source or ±200 mA over ±16V range (4-quadrant operation) at low voltage range. This enables characterization of the device under test for parametric test of I/O pins.

SENSE input

The M9186A has a SENSE input that enables accurate voltage source to the I/O pins of a device under test. This is done by having feedback loop to enable the high and low voltage amplifiers to sense the amount of current flowing while forcing a constant voltage.

Software Platform

IO Libraries Keysight IO Libraries Suite offers FAST and EASY connection to instruments and the newest version extends that capability to include modular instruments.

NEW support for PXI — The Keysight IO Libraries Suite helps you display ALL of the modules in your system. From here you can view information about the installed software or start the modules’ soft front panel. Launch the modules’ soft front panel directly from Keysight Connection Expert.

Drivers

The M9186A voltage current source is supplied with a comprehensive portfolio of module drivers, documentation, examples, and software tools to help you quickly develop test systems with your software platform of choice.

The module comes with IVICOM, IVI-C, and LabVIEW G software drivers that work in the most popular test and measurement development environments including LabVIEW and LabWindows/CVI from National Instruments, Microsoft® C/C++, C#, and VB.NET®.
