BSIDE OT9 Professional 3-in-1 Oscilloscope Graph Multimeter

The BSIDE OT9 is a next-generation portable electronic testing instrument designed for professionals who demand accuracy, portability and versatility. Instead of carrying separate instruments, OT9 integrates a digital oscilloscope, graphing multimeter, and signal generator into one compact handheld device.

Powered by a 50MHz dual-channel oscilloscope with 250MSa/s real-time sampling, OT9 captures fast-changing waveforms accurately. Professional analysis tools including FFT spectrum analysis, Persistence Mode, X-Y display, Y-T display, and automatic waveform measurements help engineers quickly diagnose complex electronic circuits.

Unlike conventional digital multimeters, OT9 features a 20,000-count graphing multimeter capable of displaying both numerical readings and real-time trend graphs. Users can easily monitor voltage fluctuations, identify transient events, and capture peak values that traditional meters often miss.

The integrated 8-waveform signal generator supports adjustable frequency, amplitude, and duty cycle, enabling waveform simulation for circuit verification, troubleshooting, and educational demonstrations without requiring additional equipment.

The 4.3-inch HD full-color touch screen delivers excellent visibility, intuitive operation, and fast access to all functions. Combined with the built-in adjustable stand and USB-C rechargeable battery, OT9 is suitable for both laboratory benches and field service.

Whether you're repairing automotive electronics, developing embedded systems, maintaining industrial equipment, servicing home appliances, or teaching electronics, the BSIDE OT9 provides professional-grade measurement capability in one compact handheld instrument.
