80MHz 2-Channel Oscilloscope Multimeter with Signal Gen

3-in-1 Diagnostic Scope for Automotive & Electrical Work

This 3-in-1 instrument combines an 80MHz digital storage oscilloscope, a 6000-count True RMS multimeter, and a 1Hz-5MHz signal generator in a single portable unit. Designed for automotive electrical diagnostics and general electronics troubleshooting, it provides clear waveform visualization, accurate measurements, and flexible signal output in the workshop or on-site.

The dual-channel oscilloscope offers up to 80MHz bandwidth (single channel) and a real-time sampling rate up to 250MSa/s, with an intuitive interface, one-key AUTO setup, and a waveform preview window for fast analysis. The True RMS multimeter measures AC/DC voltage up to 1000V, current up to 10A, resistance, capacitance, frequency, continuity, and diodes, supporting both sinusoidal and non‑sinusoidal signals. The built-in signal generator outputs sine, square, and triangle waveforms up to 5MHz, with selectable amplitudes up to 5Vpp (50Ω), ideal for circuit stimulation and sensor simulation.

Housed in a compact ABS enclosure with a 2.8" TFT color display (320 × 240), the unit runs on two included 18650 lithium batteries (approx. 10 hours oscilloscope use / 20 hours multimeter use) and supports 15W fast charging. Onboard storage saves up to 200 waveforms and 2000 measurement records, while USB PC software enables extended waveform analysis and FFT. Available in two color variants (Red ET829, White ET202D) with identical functionality.

Why It's a Smart Choice

• Three core tools in one device - Replaces separate oscilloscope, multimeter, and signal generator, reducing bench clutter and setup time.
• Optimized for field diagnostics - Long battery life, compact 100 × 210 × 40mm form factor, and included carry bag support mobile automotive and electrical service work.
• Advanced analysis features - FFT, cursors, math functions, storage, and PC connectivity support detailed troubleshooting and documentation.

FAQ

Q: Is this suitable for automotive CAN, sensor, and injector signal diagnosis?
A: Yes. The 80MHz bandwidth, dual channels, and True RMS measurements make it suitable for most automotive sensor, actuator, and communication line diagnostics.

Q: Can I use the signal generator and oscilloscope at the same time?
A: Yes. The signal generator can operate concurrently with the oscilloscope, allowing you to inject test signals while monitoring circuit response.

Q: What is included in the package?
A: The set includes the ET829/ET202D oscilloscope, dual injection test lead, scope probe, signal output clip wire, Type‑C USB cable, user manual, and cloth bag.

Q: Does it support PC connectivity for data analysis?
A: Yes. USB communication and PC software allow timing measurements, waveform recording, curve plotting, and FFT analysis on a computer.
