PicoScope 4444 differential oscilloscope
Why use the PicoScope 4444 differential oscilloscope?
There are, of course, plenty of differential probes available, all with similar inconveniences: bulky interface boxes, missing or flat batteries, snaking power leads... 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.
True differential measurements in high resolution
The PicoScope 4444’s four D9 inputs allow you to make true differential measurements. The maximum input range at full scale is ±50 V (±1000 V using the PicoConnect 442 1000 V CAT III probe), and
the maximum common-mode range is also ±50 V (also ±1000 V with the PicoConnect 442 probe). You can set the scope to measure at resolutions of 12 or 14 bits, far better than the 8-bit resolution
typical of many oscilloscopes. The deep capture memory (up to 256 million samples shared by the active channels) is another advantage, allowing you to carry out long captures without lowering the
sampling rate.

greater bandwidth and a faster sampling rate than the PicoScope 4444, but fails to resolve the fine detail of the signal. The 12-bit resolution of the PicoScope 4444 offers 16 times as much vertical detail,
and its deeper capture memory of 256 MS gives it greater horizontal resolution, too.
