Fluke 190-202-III-S, Portable Digital Storage Oscilloscope, 200MHz, 2 Channel

The Fluke 190-202-III-S is a rugged, field-ready two-channel portable digital storage oscilloscope engineered for demanding electronic, electrical and industrial maintenance applications. With a 200 MHz bandwidth and the sampling fidelity to match, it empowers technicians and engineers to capture, analyse and troubleshoot complex waveform behaviour in automation systems, power electronics and instrumentation circuits.

Advanced Features and Benefits of the Fluke Portable Digital Storage Oscilloscope

• 200 MHz bandwidth supports accurate capture of mid-level signal dynamics.
• Two fully isolated channels enable measurement across different ground references in industrial environments.
• Real-time sample rates up to 5 GS/s and resolutions down to 200 ps provide fine detail for rapid events.
• IP51-rated rugged casing with factory calibration version (“-S” suffix) protects data integrity in field deployments.
• Built-in 5000-count digital multimeter adds versatility for voltage, resistance, continuity and other measurements.
• USB/WiFi connectivity, plus deep memory (10,000 samples per channel), ensure data capture, transfer, and analysis workflows.

Why Buy It?

The 190-202-III-S is built to address the realities of on-site troubleshooting where signals vary rapidly, systems are rugged, and downtime is costly. Its high bandwidth, fast sample rate and deep memory enable capturing transient events, noise spikes, motor-drive switching behaviour and complex three-phase interactions. Isolated inputs reduce risk when measuring across mixed-reference systems or floating circuits, especially in industrial automation and power-conversion environments. Ruggedisation, including IP51 protection, battery accessibility, and a durable transport case, makes the tool dependable for field or plant-floor use.

Versatile Uses of the Oscilloscope

• Capturing and analysing switching waveforms in variable-speed drives, inverters and motor controllers.
• Diagnosing power electronics blocks, including IGBT/IGCT gate signals, DC link disturbances, and harmonic behaviour.
• Verifying control-system timing, sensor responses, and signal integrity across automation panels.
• Monitoring industrial equipment startup transients, power interruptions or embedded systems in harsh environments.
• On-site documentation of waveform anomalies, noise sources and signal drift for maintenance teams conditioned on reliability and uptime.
