A System Multimeter with BOTH High Speed and High Accuracy The Keysight Technologies, Inc. 3458A Multimeter shatters longstanding performance barriers of speed and accuracy on the production test floor, in R&D, and in the calibration lab. The 3458A is simply the fastest, most flexible, and most accurate multimeter ever offered by Keysight.
The 3458A Multimeter for: High test system throughput Faster testing – Up to 100,000 readings/sec – Internal test setups > 340/sec – Programmable integration times from 500 ns to 1 sec Greater test yield – More accuracy for tighter test margins – Up to 8.5 digits resolution Longer up-time – Two-source (10 V,10 kΩ) calibration, including AC – Self-adjusting, self-verifying autocalibration for all functions and ranges, including AC Calibration lab precision Superb transfer measurements – – – – 8.
For High Test System Throughput – Faster system start-up Multimeter Language (ML) compatible – Faster measurements and setups 100,000 readings/sec in 4.5 digits 50,000 readings/sec in 5.
For Calibration Lab Precision – 8.5 digits resolution – 0.1 ppm DCV linearity – 100 ppm ACV absolute accuracy – 4 ppm/year optional stability In the calibration lab, you’ll find the 3458A’s 8.5 digits to have extraordinary linearity, low internal noise, and excellent short term stability. The linearity of the 3458A’s Multislope A to D converter has been characterized with state-of-the-art precision. Using Josephsen Junction Array intrinsic standards, linearity has been measured within ± 0.
For High Resolution Digitizing – 16 bits at 100,000 samples/sec – Effective rates to 100 Msamples/sec – Signal bandwidth of 12 MHz – 10 ns timing with < 100 ps jitter Easily acquire waveforms Direct sampling function Sequential sampling function Simple, application-oriented commands in the Keysight Multimeter Language (ML) make the task of waveform digitizing as easy as measuring DCV. Simply specify the sweep rate and number of samples.

Section 2: Resistance continued Measurement Consideration Keysight recommends the use of PTFE* cable or other high impedance, low dielectric absorption cable for these measurements.
Section 3: DC Current Measurement Considerations Keysight recommends the use of PTFE cable or other high impedance, low dielectric absorption cable for low current measurements. Current measurements at rates < NPLC 1 are subject to potential noise pickup. Care must be taken to provide adequate shielding and guarding to maintain measurement accuracies.
Section 4: AC Voltage General Information The Keysight 3458A supports three techniques for measuring true rms AC voltage, each offering unique capabilities. The desired measurement technique is selected through the SETACV command. The ACV functions will then apply the chosen method for subsequent measurements. The following section provides a brief description of the three operation modes along with a summary table helpful in choosing the technique best suited to your specific measurement need.
