Fluke 190-204-III ScopeMeter Portable Oscilloscope

The Fluke 190-204-III ScopeMeter is a portable, powerful, four-channel oscilloscope suitable for maintenance managers and consultants working in manufacturing, equipment installation, and field service. It is ideal for commissioning, servicing, and troubleshooting industrial machinery, automation and process controls, and power conversion electronics (DC to 500MHz).

Capable of capturing accurate, detailed waveforms that allow you to see noise and other disturbances, the Fluke 190-204-III ScopeMeter features a 200MHz bandwidth, fast sampling rate up to 5.0GS/s, and four independent, isolated inputs (up to 1000V). Additionally, it offers a 200 ps resolution and a deep memory capable of storing up to 10 000 samples per channel. Memory/ measurement functions aid the user with diagnosing difficult problems such as complex waveforms, induced noise, intermittent events, and signal fluctuations/ drift:

TrendPlot™ Paperless Recorder: enables long-term automatic measurements; this mode plots key values allowing you to identify intermittent faults quickly.
ScopeRecord mode: this mode stores up to 48 hours of data ensuring you can capture fast and intermittent glitches; it saves up to 30 000 points per input channel facilitating low-frequency signal analysis.
Replay function: automatic capture and replay of up to 100 screens.
Connect-and-View Triggering: intelligent, automatic triggering on fast, slow, and complex signals.

Furthermore, the Fluke 190-204-III ScopeMeter can take timing- and amplitude-related measurements and conduct FFT analysis on frequency spectrums. It is possible to compare multiple test points across the circuit.

Data is displayed on the Fluke 190-204-III ScopeMeter’s large, bright, colour display. Saved measurements and waveforms may be transferred to a PC via a USB or Wi-Fi interface (FLUKE-190-204-III-S only as a Wi-Fi dongle is required).

The Fluke 190-204-III ScopeMeter is optimised for on-site use. It has a safety rating of CAT III 1000V/ CAT IV 600V and an IP51-rated, dust- and drip-proof casing with an easy-to-access battery door that enables quick, simple battery changes.

The Fluke 190-204-III ScopeMeter is a rugged, reliable, precise four-channel oscilloscope.
