Hardware platform


The M9181A 6½ digit, DMM is PXI compliant, using either cPCI (J1) or PXI-1 (J1). The M9181A uses fast data interfaces and can be integrated with other test and automation modules in a PXI, Compact PCI, or Hybrid chassis. The PXI format offers high performance in a small, rugged package. It is ideal for many automated test systems. A wide array of complementary PXI products are currently available. Keysight products include switches, multiplexers, digitizers, waveform generators and local oscillators.

Software platform

IO Libraries

Keysight IO Libraries Suite offers fast and easy instrument connections. IO Libraries Suite 16.1 adds support for PXI, helping you display all of the modules in your system and view information about installed software. In addition, IO Libraries Suite 16.1 and newer versions allow you to more easily find the right driver and start module soft front panels directly with Keysight Connection Expert.

National Instruments IO libraries are also supported and may be used along with Keysight IO libraries.


Keysight’s digital multimeters include software drivers for WindowsXP, Windows Vista and Windows 7. These drivers work in the most popular test and measurement development environments, including LabVIEW, Visual Studio (C, C++, C#, Visual Basic), and MATLAB.

Easy software integration

Application code examples that demonstrate DMM setup and basic functionality are included for LabVIEW, Visual Basic and C/C++, C#, and MATLAB. These application code examples help you integrate the DMM module into your measurement system.

Soft front panel

The soft front panel provides easy to use instrument control. Its graphical user interface guides developers through module setup so users can quickly configure the DMM.
