Fluke has introduced a new 500MHz bandwidth, 4-channel, handheld oscilloscope. Targeted at industrial electronics maintenance engineers, electronic field service engineers and other professional engineers and technicians in the field, the rugged Fluke 190-504 Series II ScopeMeter offers 4 isolated input channels which give the option to simultaneously measure voltages and current independent of the reference potential in harsh industrial environments up to 1000V CAT III /600V CAT IV. The device offers a range of tools in one - a high performance portable scope with 500MHz bandwidth, real time sample rates up to 5GS/s, 4-channel isolated inputs for differential measurements and four meter measuring options. It offers advanced analysis and measurement capabilities for complex troubleshooting, using 4 input channels to inspect signal amplitude, time or waveform correlation. Use of the automatic power and energy measurements allow an understanding of efficiency and energy in industrial power systems, and inspection of voltage and current waveforms of modulated power signals. Specific analysis such as amplitude versus frequency domain spectrum, pass/fail envelope or capturing complex signals using pulse width trigger are all possible.
