Oscilloscope Offers 4-ch Channel High Resolution Oscilloscope With Differential Inputs

Fairport, NY:  Saelig Company, Inc. has introduced the PicoScope 4444 High-resolution Differential Oscilloscope which features four true differential input channels and a range of accessories for measurements from millivolt to 1000 V CAT III applications. It has been designed specifically for making accurate voltage waveform measurements on circuits that are not ground-referenced, avoiding the dangers of equipment damage due to short circuits.

The PicoScope 4444 can facilitate differential voltage measurements in the presence of common-mode signals, with 14-bit resolution and 20MHz bandwidth on all four differential channels and 256MSa waveform capture memory. It is ideal for the precise analysis of complex waveforms ranging from biomedical sensors to current probes and 1000 V CAT III power distribution circuits. The PicoScope 4444 offers a choice of complementary 1:1 low-voltage and 25:1 1000V CAT III probes to address these and other situations. The oscilloscope has an intelligent probe interface that can provide power for a wide range of PicoConnect voltage probes, current probes such as Hall effect DC/AC, and Rogowski coil type active current probes. The scope automatically detects when a compatible probe is connected and sets the corresponding units and vertical settings in the supplied PicoScope 6 software.

The USB-powered PicoScope 4444 is available in two kits that include key accessories:

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 the use of two input channels and an A–B math function to observe the differential signal of interest. But, in addition to 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. A ground-referenced scope can’t be used as it will cause a short circuit. External differential probes are a solution but they are quite expensive and cumbersome, with each probe requiring its own power supply. The PicoScope 4444 provides the solutions for each of these situations, but it can also be used as a general purpose scope with all the useful features that PicoScope software provides - such as serial bus decoding, mask and limit testing, math channels and automatic measurements.

Made by Pico Technology, Europe’s award-winning oscilloscope adapter manufacturer, PicoScope 4444 High-resolution Differential Oscilloscopes are available now from Saelig Company, Inc. their USA technical distributor.
