Product Description
- 4 fully differential high-impedance inputs
- 20 MHz bandwidth
- Flexible 12 and 14-bit resolution
- 256 MS deep memory
We and our distributors supply three preconfigured kits with everything you need to get started with differential measurement. Each kit includes a PicoScope 4444 high-resolution differential oscilloscope and three differential voltage probes with Pico D9 connectors. The kits also come with a TA271 D9‑BNC adaptor, which lets you use traditional oscilloscope voltage probes and current probes, to make single-ended measurements with a ground-referenced probe. Finally, all three kits are delivered in a sturdy carry case
