True differential measurements in high resolution
The PicoScope 4444’s four inputs allow you to make true differential measurements. The maximum input range at full scale is ±50 V (±1000 V CAT III using the PicoConnect 442 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.
FFT spectrum analyzer
The spectrum view plots amplitude against frequency, revealing details that would otherwise be hidden in an oscilloscope view. It is ideal for finding noise, crosstalk or distortion in signals. The spectrum analyzer in PicoScope is of the Fast Fourier Transform (FFT) type that, unlike a traditional swept spectrum analyzer, can display the spectrum of a single, non-repeating waveform. With up to a million points, PicoScope’s FFT has excellent frequency resolution and a low noise floor.
