Product Overview

Most oscilloscopes employ grounded BNC inputs where the shell is tied directly to ground, which means that expensive Active Differential Probes are required for floating or differential measurements that are not referenced to ground. The new PicoScope 4444 High Resolution, Differential Input Oscilloscope, allows the use of inexpensive Passive Differential Probes where floating or differential signals are encountered. Two kits provide a choice of differential probes for either low level voltages or up to 1000V CAT III, for easy connection to floating voltages or differential signals, plus a choice of current probes for power measurements. 12 & 14 bit digitizers with vertical zoom allow visualization of very low level signals. Serial bus decoders, makes for easy decode of differential busses such as CAN FD and RS422/485. With its small size and all the features that PicoScope software provides, it make a great general purpose scope for the bench or the field.
  • 4 fully differential high-impedance inputs
  • 20 MHz bandwidth
  • Flexible 12 and 14-bit resolution
  • Maximum input range at full scale is ±50V (±1000V using the PicoConnect 442 1000V CAT III probe)
  • Maximum common-mode range is also ±50V (also ±1000V with the PicoConnect 442 probe)
  • 256 MS deep memory
  • Rejects common mode noise
  • Interface for intelligent probes and clamps
  • Low-voltage probe for sub-millivolts to 50 V
  • 1000V CAT III probe for high voltage applications
  • Serial Bus Decodes (E.g. I2C, SPI, RS232/422/485, CAN/FD, ModBus)
