This instrument features four true differential input channels and a range of accessories for measurements from millivolt to 1000 V CAT III applications. The new PicoScope addresses the perennial problem of making accurate voltage waveform measurements on circuit elements that are not ground-referenced, without the risk of short circuits that could damage the device under test or the measuring instrument.'Building on the success of PicoScope 4000 Series high-resolution oscilloscopes, the PicoScope 4444 gives electrical engineers the freedom to make differential voltage measurements in the presence of common-mode signals,' said Trevor Smith, Business Development Manager, Test & Measurement, at Pico Technology. 'The new instrument has 14-bit resolution on four channels and 256 megasample capture memory, so is ideal for precise analysis of complex waveforms ranging 'from biomedical sensors to current probes and 1000 V CAT III power distribution circuits.'Scientists and electronics engineers frequently need to make low-voltage measurements in the presence of high common-mode noise or varying offset voltages. Ground-referenced oscilloscopes require use of two input channels and an A–B math function to observe the differential signal of interest. But, as well as this requiring two input channels, most scopes don’t have a high enough common-mode rejection ratio (CMRR), nor the resolution to make measurements with sufficient precision.Engineers working on polyphase power distribution systems need to measure phase-to-phase AC voltages, rather than phase to ground.
