Keysight 34420A Nano-Volt/Micro-Ohm Meter, 7.5 Digit
Key Features and Functions
The Keysight 34420A nano-volt / micro-ohm meter is a high-sensitivity multimeter optimized for performing low-level measurements. This digital ohm meter combines low-noise voltage measurements with resistance and temperature functions. This new standard in low-level flexibility and performance provides you with accurate, repeatable measurements you can count on.
- High-sensitivity DCV and resistance measurements at 100 pico-volt and 100 nano-ohm
- Accurate temperature measurements with 0.003 ?C accuracy using standard platinum resistance thermometer (SPRT) probes
- Built-in low noise 2-channel scanner simplifies voltage comparisons
- Includes BenchVue software license, making it easier to connect, control instruments, and automate test sequences
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 71/2 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.
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
BenchVue Software (now included)
BenchVue software for the PC makes it simple to connect, control, capture and view Keysight’s DMMs simultaneously with other Keysight bench instruments with no additional programming.
- Visualize multiple measurements simultaneously
- Easily log data, screen shots and system state
- Rapidly prototype custom test sequences
- Recall past state of your bench to replicate results
- Export measurement data in desired format fast
- Quickly access manuals, drivers, FAQs and videos
- Monitor and control bench from mobile devices
