Product Description

The M9188A’s capability of outputting high voltages meets voltage test requirements of 0 V to +30 V, therefore, eliminating the need for design and development of additional signal conditioning circuits for applications that require voltages of up to +30 V such as an engine electronic control unit.

With the ability to provide a dynamic current source signal of up to +20 mA, the M9188A eliminates the need for an additional current transformer or source measure unit (SMU) for application tests that require current source signals.

Another unique feature of the M9188A is that it is designed with output amplifiers that provide protection from short-circuits and over-temperatures.

Every channel is designed with an output disconnect switch that is capable of providing isolation between the module and application.

With 1 MB available memory per channel, the M9188A is able to simulate waveforms with a sampling period from 2 µs to 512 µs. This effectively enables the M9188A to behave like a basic arbitrary waveform generator (ARB) for waveforms of up to 500 kSa/s update rate.

Below are some typical waveforms that can be generated with the M9188A.


The M9188A dynamic DAC is PXI compliant, using either a PXI-1 or PXI Hybrid slot. The product can be integrated with other test and automation modules in 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 is currently available. Products include multimeters, waveform generators, local oscillators, digitizers, down converters and switch multiplexers.

IO Libraries

Keysight input/output or 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 such as 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 soft front panel of the module. Launch the soft front panel of the module directly from Keysight Connection Expert.


The M9188A dynamic DAC 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.
