Agilent’s M9182A and M9183A 6½ digit high performance
PXI digital multimeters (DMMs) offer fast throughput, flexible measurements, and trustworthy results. The M9182A
provides ten built-in measurement types with all the accuracy and stability you would expect from an Agilent 6½
digit DMM. The M9183A provides the same capabilities as
the M9182A, with market-leading measurement speed of
up to 15,000 readings per second, additional ranges, and a
DC source.

Compliance

Easy software integration

The M9182A and M9183A 6½ digit DMMs are PXI
compliant, using either a cPCI (J1), PXI-1 (J1) or PXIe
Hybrid slot. Designed to benefit from fast data interfaces,
an M9182A or M9183A DMM can be integrated with other
test and automation modules in a PXI, CompactPCI, or
Hybrid chassis. 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 from Agilent include switches, multiplexers,
digitizers, waveform generators, and local oscillators.

Application code examples are included for LabVIEW,
Visual Basic, C/C++, C#, and MATLAB – demonstrating
DMM set up and basic functionality. These application
code examples can be used to help you integrate the DMM
module into your measurement system.

Soft front panel
The soft front panel provides easy to use instrument
control. The M9182A and M9183A graphical user interface
guides developers through module setup so users can
quickly configure the DMM.

S oftw a r e P l a t f o r m
IO Libraries Suite
Agilent IO Libraries Suite offers fast and easy instrument
connections. IO Libraries Suite 16.1 supports PXI, helping
you display all of the modules in your system, view
information about installed software and allows you to
more easily find the right driver and start module soft front
panels directly with Agilent Connection Expert.
National Instruments IO libraries are also supported, and
may be used along with Agilent IO libraries.

Drivers

One notable feature of the soft front panel is the Driver Call
Log which allows the user to see the driver calls for each
button pushed. The user can then incorporate the driver
calls into the their application program – enabling fast and
easy program development.

Agilent’s digital multimeters come complete with software
drivers for Windows® XP, Windows Vista, and
Windows 7 (32 and 64 bit). These software drivers work
in the most popular test and measurement development
environments including: LabVIEW, Visual Studio® (C, C++,
C#, Visual Basic), MATLAB, and VEE.

Calibration
Each M9182A and M9183A DMM is factory calibrated
and shipped with an ISO-9002, NIST-traceable calibration
certificate.
Calibration is required once per year. A documented
calibration process allows you to do in-rack calibration
using standard calibration sources. Alternatively, Agilent
and 3rd party calibration labs offer calibration services for
the M9182A and M9183A DMMs.

Defin itions f o r s p e c i f i c a t i o ns
Specification (spec): Represents warranted performance of a calibrated instrument that has been stored for a minimum
of two hours within the operating temperature range of 0 to 55 °C, unless otherwise stated, and after a one hour warm-up
period. The specifications include measurement uncertainty. Data represented in this document are specifications unless
otherwise noted.
Typical (typ): Represents characteristic performance, which 80% of the instruments manufactured will meet. This data is
not warranted, does not include measurement uncertainty, and is valid only at room temperature (approximately 25 °C).
Nominal (nom): The expected mean or average performance, or an attribute whose performance is by design, such as the
50 Ω connector. This data is not warranted and is measured at room temperature (approximately 25 °C).
Measured (meas): An attribute measured during the design phase for purposes of communicating expected performance,
such as amplitude drift vs. time. This data is not warranted and is measured at room temperature (approximately 25 °C).
Note: All graphs contain measured data from several units at room temperature unless otherwise noted.

Transaction Speed
Transactional I/O speed is a single reading measurement.
This is important when you are taking many single
measurements with the DMM. The M9183A delivers the
highest transactional measurement speed in its class.
These fast readings, up to 15,000 readings per second with
a read interval rate of 66 µs, provides the lowest latency,
translating into higher test-system throughput and lower
cost of test per unit tested.

Variable delay can be programmed to allow fully settled
readings in most configurations.

Time frame of a single measurement
Minimum read interval = 66 µs (M9183A)

T h e Mo d u l ar Tang r am
The four-sided geometric symbol that appears throughout this
document is called a tangram. This seven-piece puzzle originated
in China a few centuries ago. The goal is to create shapes—from
simple to complex—that form an identifiable silhouette. As with
a tangram, the possibilities may seem infinite as you begin to
create a new test system. With a set of clearly defined elements—
architecture, hardware, software—Agilent can help you create the
system you need, from simple to complex.
