The Keysight 3458A System
Multimeter heightens test perfor-
mance in three phases of your pro-
duction test: faster test system start-
up, faster test throughput, and lower
cost of ownership 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
Keysight Multimeter Language (ML)
offers a standard set of commands
for the multimeter user that consists
of easily understood, readable com-
mands. 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 combi-
nation of accuracy, resolution, and
speed. The 3458A Multimeter fits
your needs from 4.5 digit DC volts
measurements at 100,000/second,
to 8.5 digit DC volts measurements at
6/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/second with full
accuracy 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
output the result at 340/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/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 ppm 24 hour
DC volts accuracy, 100 ppm AC volts
accuracy and its standard functions of
DCV, ACV, DCI, ACI, ohms, frequency
and period. Greater measurement
accuracy from your dmm means higher
confidence 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 stabil-
ity internal standards. This self- or
auto-calibration eliminates measure-
ment errors due to time drift and
temperature changes in your rack or
on your bench for superior accuracy.
When it’s time for periodic calibration
to external standards, simply con-
nect a precision 10 VDC source and
a precision 10 kΩ resistor. All ranges
and functions, including AC, are auto-
matically calibrated using precision
internal ratio transfer measurements
relative to the external standards.
The 3458A’s reliability is a product of
Keysight’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 confidence
in the 3458A’s reliability is reflected
in the low cost of the option for
additional years of return-to-repair.
