ZOYI ZT-703S 3-in-1 Digital Oscilloscope Multimeter & Signal Generator (50MHz)

Beyond its massive 25,000-count True RMS multimeter capabilities, the ZT-703S features a highly capable dual-channel digital oscilloscope boasting a 50 MHz analog bandwidth and up to a 280 MSa/s real-time sampling rate. This means it can easily capture fast transients, electrical noise, and high-frequency communication protocols like SPI and I2C. Coupled with a built-in signal generator for injecting test waveforms into your circuits, and an internal memory that allows you to save and export waveform screenshots to your PC via USB, it is an absolutely indispensable tool for serious hardware engineers, auto electricians, and advanced hobbyists.

Key Features & Functional Advantages

• 3-in-1 Multifunctionality: Completely replaces three separate benchtop instruments by integrating a dual-channel oscilloscope, a high-accuracy digital multimeter, and a multi-waveform signal generator.

• Dual-Channel 50MHz Scope: Features two dedicated BNC inputs, a 50 MHz analog bandwidth, and up to a 280 MSa/s sampling rate, perfectly capable of capturing complex, high-speed logic and automotive CAN bus signals.

• 25,000-Count Precision Multimeter: Provides laboratory-grade accuracy (up to 0.05% basic DCV accuracy) and True RMS AC measurement, vastly outperforming standard 4,000-count or 6,000-count entry-level meters.

• 3.5-Inch IPS Color Display: The large, high-contrast screen provides wide viewing angles and vibrant colors, allowing you to clearly view both oscilloscope channels simultaneously alongside numerical measurements.

• Waveform Storage & Export: Allows you to capture screenshots of active waveforms directly to the internal memory and transfer them to a computer via the Type-C USB port for detailed secondary analysis.

Perfect For

• Embedded Hardware Engineering: The ultimate all-in-one bench tool for designing, testing, and debugging high-speed microcontrollers, sensors, and communication buses.

• Automotive Diagnostics: Perfect for auto-electricians needing to visualize erratic fuel injector pulses, crank sensor signals, and ignition timing directly at the vehicle.

• Audio Equipment Repair: Using the built-in signal generator to inject a clean sine wave into a faulty amplifier, and using the dual-channel scope to trace the signal and find exactly where distortion is introduced.

• Field Service Technicians: Providing the diagnostic power of a complete test bench in a highly portable, rechargeable unit that easily fits inside a standard tool bag.
