Portable Oscilloscopes

Fluke Corporation, the global leader in portable electronic test and measurement technology, has introduced the Fluke ScopeMeter® 190 Series II handheld portable oscilloscopes, the first four-channel scopes designed for harsh industrial environments. These new portable scopes are the first safety rated for CAT III 1000 V/CAT IV 600 V environments. The four input channels are fully isolated from each other to perform differential floating measurements, a critical consideration for troubleshooting fixed-installation three-phase power electronic devices like variable speed motor drives. The chassis is sealed from the environment with no cooling slots or fans to expose the instrument. It carries the IP51 dust and drip proof rating, tough enough to use safely on the factory floor and in the field. The Fluke 190 Series II oscilloscope meets the growing need for four-channel portable oscilloscopes in industrial environments. Power electronics are used increasingly in solar and wind energy generation and to maximise efficiency or reduce power consumption especially in heavy-duty electro-mechanical applications. Their fast sampling rate, up to 2.5 GS/sec and 400 pico second resolution, helps users capture electrical noise and other disturbances to diagnose exactly what is going on. With100 MHz and 200 MHz models, they deliver the bandwidth needed to cover both today’s needs, and tomorrow’s. Users can: view and measure harmonics, transients, and loads in three-phase power systems; troubleshoot dc to ac converters for faulty insulated-gate bipolar transistors (IGBTs) and control circuits; and view and measure pulse width modulated waveforms (PWM) for reflections and transients.
