Display DMM results in ways you never have before
Easily display, save and document
your measurement results
Number mode provides
the traditional “digits” view
of measurements.
Histogram mode gives you a statistical
view of your measurements.

for you: USB, LAN/LXI Core
(optional on 34460A), GPIB
(optional on 34460A & 34461A).
• Easily access the front-panel USB memory connector.
Display DMM results in ways you never have before
The free DMM connectivity
utility helps you get your
job done faster
Capture and export data to your PC with
drag and drop ease

longer periods under PC control or upload data
captured directly from the instrument. Export data
from a single DMM, or multiple DMMs with time
alignment, to popular tools such as Microsoft
Excel, Microsoft Word and MATLAB. Simplify test
documentation and data analysis without the hassles
of programming.
Visualize multiple DMM outputs at once
Display single measurements, charts, or histograms
from a single instrument or up to four DMMs
simultaneously. See what’s happening on your
bench, all on one display—to spot correlated trends
you might otherwise miss.
Simplify instrument confi guration
Instrument controls provide easy measurement setup
and instrument state management. Reduce set-up
times and quickly reconfi gure for new tests.

In a rack or on a bench real-world signals are never fl at. They have some level
of AC signal riding on top from power line noise, other environmental noise, or
injected current from the meter itself. How well your meter deals with these
extraneous factors and eliminates them from the true measurement makes a big
difference to your accuracy. Behind the scenes, Agilent’s Truevolt technology
accounts for measurement errors created by these real-world factors so you can
be confi dent in your measurements and it is only available on Agilent DMMs.
Truevolt technology starts with an analog-to-digital converter that enables a
patented metrology-grade architecture. Using this architecture, Agilent delivers
a good balance of measurement resolution, linearity, accuracy, and speed at a
value price, all derived and guaranteed per ISO/IEC 17025 industry standards.

MEASUREMENT
Worry about the quality of your design, not the quality
of your measurements
5
What Truevolt technology means to you:
You can measure your real-world signals,
not instrument error
Noise and injected current: Agilent Truevolt DMMs contribute less than
30% of the injected current than alternatives. Compared to some lower cost
alternatives, Truevolt DMMs offer almost 100% less noise.
You can take advantage of expanded
measurement functionality
Compared to the 34401A DMM, Truevolt DMMs offer expanded
current ranges from 100 µA to 10 A. We have also added a tem-
perature measurement function (RTD/PT100, 5 kΩ thermistor).
Additionally, diode measurement capability has been expanded
to allow a larger full-scale voltage to be measured (5 V) to
enable the measurement of more diode types such as LEDs.
Measure with unquestioned Truevolt confi dence
You can measure your real-world signals with confi dence
All Truevolt DMM specifi cations are tested and guaranteed for compliance
with ISO/IEC 17025 standards so you can prove the effectiveness
of your lab or production line’s quality management system.
Many lower-cost DMMs in this class do not carry a guarantee
of their measurement specifi cations.

accuracy is
degraded when
signals have energy
contained in higher
frequencies than a

Crest factor: the ratio of the
peak value to the RMS value
of a waveform
Digital AC rms measurements: For meters in this class, only Agilent uses
digital direct sampling techniques to make AC rms measurements. This results
in a true rms calculation technique that avoids the slower response of analog
RMS converters used in all other vendor’s 6½ digit DMMs. This allows for
crest factors up to 10 without additional error terms. This is a unique, patented
technique – only used by Agilent.

Input bias current: Ideally, no current fl ows into the measurement terminals
of your DMM. In real measurement situations, there are always input currents
creating additional measurement errors. Truevolt DMMs take care of input bias
current. Some alternative DMMs offer 20% to infi nitely poorer performance
(some are too noisy to measure).

Move to the next-generation
34401A DMM with 100% assurance
Like most 34401A DMM owners, you rely on your
DMM and you trust the answers it gives you. Now,
with the Agilent Truevolt 34461A DMM, you can
get all of the advantages of the 34401A and more.
Now you can get faster answers and have even
more confi dence in your results.
The best news of all? You can migrate from the
34401A to the 34461A without a hassle. No need
to rewrite your software programs or spend hours
learning a brand-new, complicated interface.
Use your existing programs: The 34461A
DMM is the industry’s only 100% drop-in, SCPI-
compatible replacement for the 34401A DMM.
Other DMMs may claim 34401A SCPI compat-
ibility, but only a subset of SCPI commands are
implemented.
No long learning curve: The Truevolt DMMs
were designed by the same team that created the
34401A. The team kept 34401A measurements,
reliability and familiarity in mind as they created the
Truevolt family of DMMs. So you can use it without
spending hours learning how.
The 34461A represents everything you have known
and trusted with your Agilent DMM measurements
for decades – it just keeps getting stronger.
Migrate with confi dence: Everything you
depend on with the 34401A and more

Measurement considerations All frequency counters are susceptible to error when
measuring low-voltage, low-frequency signals. Shielding
inputs from external noise pickup is critical for minimizing
measurement errors.
Autozero OFF operation
Following instrument warm–up at a stable ambient temperature ±1 °C and <10 minutes.
Add 0.0002% of range + 5 µV for DCV or + 5 mΩ for resistance.
Measurement settling considerations
ACV, ACI, Frequency, Period
Default delays are selected to give fi rst reading right for most measurements. Errors will
occur when attempting to measure the frequency or period of an input following a DC
offset voltage change. The input blocking RC time constant must be allowed to fully settle
(up to 1 second) before the most accurate measurements are possible.
Applying >300 V ACrms or >1 Arms will cause self-heating in signal-conditioning com-
ponents. These errors are included in the instrument specifi cations. Internal temperature
changes due to self-heating may cause additional error on other functions or ranges.
The additional error will generally dissipate within a few minutes.
DCV, DCI, Resistance
Applying >1 A DC will cause self-heating in signal-conditioning components. These errors
are included in the instrument specifi cations. Internal temperature changes due to self-
heating may cause additional error on other functions or ranges. The additional error will
generally dissipate within a few minutes.
Reading settling times are affected by source impedance, cable dielectric characteristics,
and input signal changes. Agilent recommends the use of PTFE or other high-impedance,
low-dielectric absorption wire insulation for these measurements.

Specifi cation (spec)
The warranted performance of a calibrated instrument that has been stored for a
minimum of 2 hours within the operating temperature range of 0 – 55 °C and after a
60-minute warm up period. All specifi cations include measurement uncertainty and
were created in compliance with ISO-17025 methods. Data published in this document
are specifi cations (spec) only where specifi cally indicated.
Typical (typ)
The characteristic performance, which 80% or more of manufactured instruments will
meet. This data is not warranted, does not include measurement uncertainty, and is
valid only at room temperature (approximately 23 °C).
Nominal (nom)
The mean or average characteristic performance, or the value of an attribute that is
determined by design such as a connector type, physical dimension, or operating speed.
This data is not warranted and is measured at room temperature (approximately 23 °C).
Measured (meas)
An attribute measured during development for purposes of communicating the expected
performance. This data is not warranted and is measured at room temperature (ap-
proximately 23 °C).
TCAL
The temperature at which the instrument was calibrated.
