The Pico Technology PICOSCOPE 4444 1000 V CAT III Kit is a 20Mhz high-resolution differential oscilloscope with three passive differential voltage probes and one TA271 single-ended D9-BNC adaptor. Its intelligent probe interface automatically configures the PicoScope display to probes. The four D9 inputs allow you to make true differential measurements. The 12bit resolution of the PicoScope 4444 offers 16 times as much vertical detail.
The PicoScope 4444 uses specially designed passive voltage probes that have smaller and lighter (or no) interface boxes. The PicoScope 4444 has high-resolution and deep memory and lets you make multiple differential measurements at the same time, while never occupying more than one power socket. Its intelligent probe interface automatically configures the PicoScope display to your probes, so you don’t have to.
