The Agilent 3458A System Multimeter
heightens test performance in three
phases of your production test: faster
test system start-up, faster test
throughput, and lower cost of owner-
ship through longer system uptime,
designed-in reliability, and fast and
easy calibration.
Faster system start-up
The value of a fast system multimeter
in production test is clear. But it is
also important that the dmm programs
easily to reduce the learning time for
new system applications. The Agilent
Multimeter Language (ML) offers a
standard set of commands for the
multimeteruser that consists of easily
understood, readable commands.
Easier programming and clearer
documentation reduce system
development time.
Faster measurements and setups
Now you can have a system dmm
with both fast and accurate measure-
ments. The 3458A optimizes your
measurements for the right combina-
tion of accuracy, resolution, and
speed. The 3458A Multimeter fits
your needs from 4.5 digit dc Volts
measurements at 100,000 per sec-
ond, to 8.5 digit dc Volts measure-
ments at 6 per second, or anywhere
in between in 100 ns steps.
Even the traditionally slower measure-
ment functions, such as ac Volts, are
quicker with the 3458A. For example,
you can measure true rms acV at up to
50 readings per second with full accu-
racy for input frequencies greater than
10 kHz.
Besides high reading rates, the
3458A’s design was tuned for the
many function and level changes
required in testing your device. The
3458A can change function and
range, take a measurement, and out-
put the result at 340 per second.
This is at least 5 times faster than
other dmms. In addition, the 3458A
transfers high speed measurement
data over GPIB or into and out of its
75,000 reading memory at 100,000
readings per second.
You can reduce your data transfer
overhead by using the unique non-
volatile Program Memory of the
3458A to store complete measurement
sequences. These test sequences can
be programmed and initiated from the
front panel for stand-alone operation
without a controller.
Finally, the 3458A Multimeter makes
fast and accurate measurements.
Consider the 3458A’s 0.6 ppm24 hour
dc Volts accuracy, 100 ppm acVolts
accuracy and its standard functions of
dcV, acV, dcI, acI, Ohms, frequency and
period. Greater measurement accuracy
from your dmm means higher confi-
dence and higher test yields. More
functions mean greater versatility and
lower-cost test systems.
Longer system up-time
The 3458A Multimeter performs a
complete self-calibration of all func-
tions, including ac, using high stability
internal standards. This self- or auto-
calibration eliminates measurement
errors due to time drift and temper-
ature changes in your rack or on your
bench for superior accuracy. When
it’s time for periodic calibration to
external standards, simply connect
a precision 10 Vdc source and a
precision 10 kΩ resistor. All ranges
and functions, including ac, are
automatically calibrated using
precision internal ratio transfer
measurements relative to the
external standards.
The 3458A’s reliability is a product
of Agilent’s “10X” program of defect
reduction. Through extensive envi-
ronmental, abuse, and stress testing
during the design stages of product
development, has reduced the num-
ber of defects and early failures in
its instruments by a factor of ten
over the past ten years. Our confi-
dence in the 3458A’s reliability is
reflected in the low cost of the
option for two additional years of
return-to-repair. This option (W30),
when combined with the standard
one-year warranty, will give you
three years of worry-free operation.
