Product overviewThe 8.5‑digit multimeter 8558A combines high-resolution DC measurement with a high‑speed digitizer (up to 5 MS/s) for laboratory characterization and production test automation. Fast memory digitization (200 ns per reading) and high throughput support rapid characterization of transient signals and increased test-line yield.
Key features- 5 MS/s high‑resolution digitizing and up to 20 MHz analog bandwidth for voltage, 4 MHz for current
- Up to 8.5 digits resolution at slow rates; up to 100,000 readings/s at 4.5 digits for high‑speed automated systems
- Onboard memory storing up to 15 million readings
- Color graphical display with trend plots, waveforms, FFT, histogram and statistics
- Programmable front/rear electronic input switch and Visual Connection Management™ active terminals
- Multiple USB host ports (front/rear) and support for USB thumb drives
Digitizing and measurement capabilities- Voltage digitizing: 100 mV – 1000 V, up to 5 MS/s and up to 20 MHz analog bandwidth
- Current digitizing: 10 µA – 2 A, up to 5 MS/s and up to 4 MHz bandwidth
- Voltage sensitivity to hundreds of nV and current sensitivity to hundreds of pA for low‑level transient detection
