Nanovolt Performance at a Microvolt Price
The Keysight Technologies, Inc. 34420A nanoVolt/micro-Ohm
meter is a high-sensitivity multimeter optimized for performing
low-level measurements. It combines low-noise voltage
measurements with resistance and temperature functions, setting
a new standard in low-level flexibility and performance.
Take the Uncertainty Out of Your Low-Level
Measurements
Low-noise input amplifiers and a highly tuned input protection
scheme bring reading noise down to 8 nVpp. Combine this with 7½
digits of resolution, selectable analog and digital filtering, 2 ppm
basic 24-hour dcV accuracy, and a shielded, copper pin connector
and you’ve got accurate, repeatable measurements you can count on.
Two Input Channels
An integral two-channel programmable scanner simplifies voltage
comparisons. Built-in ratio and difference functions enable
automated two channel measurements without the need for an
external nanoVolt scanner. Both channels share the same low
noise specifications to ensure accurate comparisons.
SPRT Measurements
Built-in ITS-90 conversion routines accept the calibration
coefficients from your SPRT probe for direct temperature
measurement and conversion. Thermocouples, thermistors, and
RTDs are also supported.
Unequaled Versatility
The 34420A gives you the versatility to tackle your most challenging
tasks, both on the benchtop and in your automated system.
Standard features include RS-232 and GPIB interfaces, SCPI and
Keithley 181 programming language, 1024-reading memory, scaling
and statistics, and a chart recorder analog output.
Keysight IntuiLink:Easy Data Access
The included Keysight IntuiLink software allows your captured
data to be put to work easily, using PC applications such as
Microsoft Excel or Word to analyze, interpret, display, print, and
document the data you get from the 34420A. You can specify the
meter setup and take a single reading or log data to the Excel
spreadsheet in specified time intervals. To find out more about
IntuiLink visit www.keysight.com/find/intuilink.
Built-In Resistance and Temperature
The 34420A combines its low-noise nano-Volt input circuits
with a high-stability current source to provide precise low-level
resistance measurements – no more hassling with the cost and
complexity of an external current source. Three resistance modes
are included:
– Standard
– Low-power
– Voltage-limited for dry-circuit testing
Offset compensation is also provided to minimize thermal EMFs
and associated errors.
Quality You Can Count On
The 34420A gives you the quality and reliability you expect from
Keysight Technologies. From the Keysight proven >150,000 hour
Mean Time Between Failure, to its standard 1-year warranty,
Keysight stands behind you to bring a new level of confidence to
your low-level measurements.
