High-end oscilloscope
At the heart of every PicoScope 4444 is an advanced oscilloscope that offers everything you would expect and much more, including:
- 10 000 waveform circular buffer
- Up to 100 000 waveforms per second update rate
- Serial bus decoding
- Mask limit testing
- Advanced math and filtering
- Measurements with statistics
- Advanced digital triggering
- USB 3.0 connected and powered

PicoConnect 441: Measure from millivolts to A 50 V
The PicoConnect 441 differential voltage probes are suitable for voltages up to A 50 V (for higher voltages see the PicoConnect 442). The probes are fitted with industry-standard 4 mm connectors and supplied with detachable sprung hook probe tips. Other 4 mm accessories such as multimeter probes and crocodile clips are available separately

PicoConnect 442: 1000 V CAT III probes
The PicoConnect 442 is an attenuating differential voltage probe that increases the input range to 1000 V to allow the safe and cost-effective measurement of single-phase, three-phase and other signals, such as those found in motor drives and inverters
Three current probes with intelligent probe interface

Three different current probes are available with Pico D9 interfaces. TA300 and TA301 use the Hall effect to measure AC and DC currents without direct connection to the cable, and the TA368 uses the Rogowski principle for AC-only measurements. The intelligent probe interface powers the probes, so no batteries are required. It also means that when you connect either probe, the PicoScope software identifies it and configures the oscilloscope to read in amperes.
The TA300 current probe is a 40 A probe suitable for measuring signals from DC to 100 kHz. It is a precision probe for smaller currents and can resolve down to a few milliamps.
