More info and finance questions

With four true differential inputs, 12 to 14-bit resolution and wide differential and common-mode voltage ranges, the Pico Technology PicoScope 4444 and its accessories offer accurate and detailed measurement for a multitude of applications.

Key features

  • 4 high impedance differential inputs
  • 20 MHz bandwidth
  • Flexible 12 and 14-bit resolution
  • 256 MS deep memory
  • Measures non-grounded (floating) signals
  • Rejects common-mode noise
  • Intelligent probe interface
  • Low-voltage probe for millivolts to 50 V
  • 1000 V CAT III probe for high-voltage applications

Typical applications

  • Safely probe single and 3-phase voltage and current
  • Measuring power drawn by mobile and IoT devices
  • Mains quality testing
  • SMPS design
  • Hybrid and electric vehicle design
  • Motor drives and inverters
  • Biomedical electronics
  • Measuring differential signals (CAN, balanced audio) with a single channel

Intelligent differential inputs
With a traditional oscilloscope probe, single-ended measurements are made between a high-impedance input and a low-impedance ground.

With a differential oscilloscope, measurements are made between two high-impedance inputs, allowing measurements to be made across components and test points where neither side is grounded. Differential inputs also reject common-mode noise: noise picked up equally on both high-impedance inputs is rejected.

Each of the four input channels on the PicoScope 4444 features an intelligent probe interface that detects and identifies compatible probes, and powers them where necessary. Each channel can have its own choice of voltage or current probe.

Non-attenuating probes allow high-resolution, low-noise measurement of signals ranging from millivolts to ±50 V. Attenuating probes allow signals up to 1000 V CAT III to be measured. Current probes are available for currents up to 2000 A.

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.

The PicoConnect 442 probe requires no power supply or batteries. This makes it ideal for mains quality measurement and other long-term measurements.  

The differential inputs of the PicoScope 4444 allow each channel to measure signals with different common-mode voltages. As an example, consider the battery pack in an electric vehicle. You can measure across the whole pack using one channel set to an input range of ±500 V, and at the same time set the other channels to ±5 V to measure across individual cells. This arrangement allows you to take advantage of the full resolution of the oscilloscope.

TA300 and TA301 current probes
Two different current probes are available with Pico D9 interfaces. Both use the Hall effect to measure AC and DC currents without direct connection to the cable. The intelligent probe interface powers the probes, so no batteries are required. It also means that when you connect either probe, 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. 

The TA301 current probe is a switched-range 200/2000 A probe suitable for measuring signals from DC to 20 kHz bandwidth. 

In addition to the TA300 and TA301, Pico stocks a wide range of AC and DC current clamps with BNC connectors that can be connected to the PicoScope 4444 using the TA271 D9 to BNC adaptor.
