Keysight M9217A

PXIe Single-Slot 2-Channel Isolated Digitizer

Data Sheet

Introduction

The Keysight Technologies, Inc. M9217A is a PXI Express based, single-slot 2-channel, isolated

digitizer that supports up to ±256 V input voltage at 20 MSa/s sampling rate with 16-bit resolution.

With its built-in peak voltage protection of up to 400 V, the M9217A is ideal for analyzing high-voltage

and transient signals as seen in automotive, mechatronics and aerospace defense applications.

±256 V input voltage

Input channels with the ability to measure waveforms up to 256 V are ideal for analyzing

high-voltage and transient signals as seen in automotive and aerospace defense

applications. Most oscilloscopes and PXI digitizers have a maximum input range less

than 40 Vpk. This also reduces the need to add expensive input signal attenuation and

signal conditioning circuitry, saving test development time and money.

2-channel isolated, with ADCs per channel

In addition, since the ±256 V input voltage range is combined with 16-bit analog-to-

digital converters (ADCs), the isolated front-end and low input offset allows voltages

from as low as 250 mV to as high as 256 V to be measured simultaneously.

The M9217A’s individually isolated 2-channel inputs have been designed for high

performance with an A/D converter per channel to ensure the signals you measure

are accurately digitized without distortion or additional noise. Channel input range is

conﬁgurable from ±250 mV up to ±256 V, with a ﬂoating voltage up to ±40 V to accom-

modate differential waveform acquisition.

20 MSa/s sampling rate at 16-Bit resolution

The M9217A’s ability to support up to 20 MSa/s sampling rate at 16-bit resolution

enables sampling of transient waveforms like injector waveforms (Figure 1).

Built-in 400 V peak voltage protection

To support high voltage and transient signals in automotive, mechatronics and aerospace

and defense applications, the M9217A has a built-in peak voltage protection against

overvoltage spikes of up to 400 V.

32 MSa/channel with up to 1024 segmented memory

Coupled with the memory segmentation feature of up to 1024 records, the M9217A’s

32M sample memory size enables multiple bursts of data to be digitized without the

need for re-initialization between bursts. The record size is conﬁgured by selecting the

total number of samples, including pre-trigger samples.

Support for multiple trigger types

The M9217A supports different trigger types like PXI trigger bus, PXI Star, external input/

output, channel and software trigger. Conﬁgurable trigger delay and trigger hold-off

allow you to better deﬁne where record data is collected relative to the trigger event.

The conﬁgurable trigger delay feature allows precise positioning of acquisition relative to

the trigger event, while the trigger hold-off feature helps avoid false triggers.

The PXI TTL trigger output enables the M9217A digitizer to synchronize to other devices.

Multiple M9217A digitizers can be synchronized for higher channel count.

IO Libraries

Keysight input/output or IO Libraries Suite offers fast and easy connection to instru-

ments. The latest suite 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. Figure 2 shows the M9217A soft front

panel.

Drivers

The M9217A digitizer is supplied with a comprehensive portfolio of module drivers, doc-

umentation, 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.

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.

Calibration Intervals

The M9217A is factory-calibrated and shipped with a calibration certiﬁcate. Calibration is

recommended every year in order to verify product performance.
