M9216A PXI High Voltage Data Acquisition Module

Data Sheets

Introduction

The Keysight Technologies, Inc. M9216A is a multi-channel, large-range voltage measurement unit capable of acquiring dynamic positive voltage levels from multiple channels simultaneously, making it ideal for automated test equipment (ATE) in automotive electronics applications.

Product description

The M9216A is a two slot, PXI-based, high voltage data acquisition module with a 16-bit resolution that allows simultaneous measurement of 8 channels of positive voltages ranging from 1 mV to 100 V. Each channel in the module comes with a concurrent 5 V and 100 V measurement range instead of having multiple switchable voltage ranges. This allows each channel to acquire signals that fluctuate between very low and very high voltage levels without the need for switching ranges and doing separate measurements.

The M9216A module also comes with a built-in 32 to eight multiplexer, enabling 32 measurement ports to be connected to the eight acquisition channels expanding it to a full blown 32 channel acquisition module. Alternatively, these channels can also be routed out via auxiliary output connector J101 eliminating the need for external multiplexers and pin matrix cards for additional measurements.

With the support of up to 32 channels with each channel equipped with dual concurrent measurement ranges, the M9216A module is capable of doing fast parallel voltage level measurements with guaranteed accuracy. This is ideal for the automotive industry and since most automotive applications do not require negative voltage measurements, the M9216A’s 16-bit ADC is fully used for positive voltages giving it better resolution hence better accuracy.

Easy Setup, Test, and Maintenance

Hardware platform

Compliance

The M9216A data acquisition module is PXI compliant, using either a cPCI, PXI-1 or PXI Hybrid slot. The product 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 is currently available. Products include multimeters, waveform generators, local oscillators, digitizers, down converters and switch multiplexers.

Input range

The M9216A comes with a large input range with dual concurrent measurement range of 5 V and 100 V for each channel. The 5 V range caters for voltage levels of 1 mV to 5 V while the 100 V range caters for voltage levels of 20 mV to 100 V, enabling every channel to acquire voltage levels ranging from 1 mV to 100 V without the need for switching ranges, making it ideal for fast measurement needs.

Measurement channels & auxiliary outputs

The built-in 32 to eight multiplexer is constructed where each dual range acquisition channel in the M9216A is connected to four ports through a 4-to-1 multiplexer, two of the ports can also be routed out via the auxiliary output connector J101. Every eight ports connect to a one of four floating commons making it one acquisition bank as shown in Figure 1, making a total of four acquisition banks.

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 M9216A high voltage data acquisition module 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 IVI-COM, 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

Easy software integration

The module software support provides context sensitive help, complete documentation and code examples that allow a quick module set up and basic acquisition functionalities. These code examples can be easily modified, so that the card can be quickly integrated into a test system. Included are application code examples for LabVIEW, LabWindows/CVI, Visual Studio C, C++, and C# and Visual Basic.
