Keysight 3458A Precision Digital Multimeter, 8½ Digit
The Keysight multimeter 3458A has established itself as one of the standard high-end digital multimeters. It offers high-precision and fast digitizing for calibration labs or fast throughput in test environments. For some time, the device had to be discontinued because components no longer complied with the RoHS specifications. Now this precision device is back - fully compatible and yet completely revised with modern components, RoHS-compatible and a housing in the current, cool anthracite grey.
- New version with modern components - fully compatible with previous models.
- 8½ digit resolution.
- Extraordinary high accuracy and longtime stability.
- Superior AC voltage measurements.
- 100,000 readings per second at 4½ digits, 6 readings per second at 8½ digits.
- Measurement functions: DC voltage and current, AC voltage and current (true RMS), 2-/4-wire resistance, frequency and period.
- GPIB interface.

Frequently Asked Questions:
Question: What is the difference between the versions HP3458A, Agilent 3458A, Keysight 3458A?
Answer: In principle, the variants are one and the same device. It was originally developed and introduced by Hewlett-Packard in 1989 as HP3458A, then continued by Agilent Technologies. Keysight Technologies has been the new name of the electronic measurement division of Agilent since 2014. Keysight has redesigned the 3458A and relaunched it in a new anthracite housing. For users of the 3458A variants in "white" - what remains unchanged, what's new?
- What remains the same?
Fully compatible: Same form, fit and function. Same specifications as released in 1989. Same programming codes. Same I/O connectivity. Same part number and accessories. - What has changed?
RoHS compliant. New color. New PCB assemblies (DC input board, AC board, A/D board, out-guard controller board, in-guard power supply board, out-guard power supply board). Extended memory (former option 001) is now included.
Question: What is the Keysight 3458A typically used for?
Answer: The Keysight 3458A is high precision. It offers 8½-digits resolution and high-precision digitizing with up to 24 bits. This makes it predestined for reliable, accurate measurements in calibration laboratories.
With a maximum speed of 100,000 measurements per second (still excellent 4½-digit resolution), it is suitable for a wide range of applications in test environments.
Question: Which physical measurands can the Keysight 3458A measure?
Answer: The Keysight 3458A measures DC voltage and AC voltage (true RMS), DC current and AC current, resistance (2- and 4-wire), frequency and period. The DC voltage ranges are 100 mV, 1, 10, 100, and 1000 V. The DC current ranges are 100 nA, 1, 10, 100 µA, 1, 10, 100 mA, and 1 A. The resistance ranges are 10, 100 Ω, 1, 10, 100 kΩ, 1, 10, 100 MΩ, and 1 GΩ. In addition, various mathematical functions are available.
