Step into a new era of precision and flexibility with the WiFiScope WS4 DIFF — the high-resolution, battery-powered differential PC oscilloscope that redefines portable measurements. Designed for professionals who need absolute freedom without sacrificing performance, the WS4 DIFF delivers industry-leading capabilities wherever your work takes you.

Featuring four fully isolated differential input channels, a 50 MHz analog bandwidth, and selectable 12, 14, or 16-bit resolution, the WiFiScope WS4 DIFF captures every tiny detail with breathtaking clarity. Thanks to its huge 128 kSample memory and powerful 50 MSa/s sampling speed (or 25 MSa/s depending on the model), you can zoom deep into your signals without losing resolution or quality. Experience signal detail that standard 8-bit oscilloscopes simply cannot match.

Connectivity is seamless and versatile. Whether you prefer fast SuperSpeed USB 3.0, a stable wired LAN connection, or complete wireless freedom via WiFi, the WS4 DIFF adapts to your needs. Powered by a long-lasting lithium-ion battery, it operates for hours independently, ensuring full galvanic isolation and maximum safety, even in the harshest environments.

The WS4 DIFF is built tough for real-world use, with a rugged, shock-absorbing design that protects connectors and ensures durability on site or in the lab. Compact and lightweight, it’s perfect for mounting near hard-to-reach systems, on moving machinery, or anywhere cabling is impractical. No other oscilloscope in its class offers this level of safety, portability, and measurement performance.

But the WS4 DIFF is much more than an oscilloscope. It’s also a high-performance digital multimeter, a protocol analyzer, and a powerful data analysis tool — all driven by TiePie’s advanced Multi Channel software. Quick Setups, customizable toolbars, and sophisticated mathematical processing blocks make it incredibly easy to dive deep into complex measurements and gain real insight fast.

Every WS4 DIFF includes premium differential measure leads, 1:10 attenuators, a carrying case, and essential accessories to get you measuring immediately. Plus, with free software and firmware updates and optional extended warranties, you can be confident your investment will continue delivering for years to come.

Wherever your measurements need to go, the WiFiScope WS4 DIFF gives you the freedom, precision, and reliability to lead the way.
