Description:

The TOOLTOP ET928 is a 3-in-1 handheld testing device that combines the functions of an oscilloscope, a digital multimeter, and a signal generator. However, despite some listings mentioning "20MHz," its actual oscilloscope bandwidth is 12MHz with a 50MS/s sampling rate. Moreover, it is designed for electronic hobbyists, engineers, and technicians who need a versatile tool. In addition, the ET928 works well for circuit debugging, routine maintenance, and automotive diagnostics. As a result, users benefit from an all-in-one solution that saves both time and space in their toolkit.

Key features:

    • 3-in-1 functionality: Combines an oscilloscope, multimeter, and signal generator in a single, compact device.
    • Color display: Features a 320x240 pixel color screen with a white backlight, providing clear and easy-to-read measurements and waveforms.
    • Portability: Weighing approximately 250g, its lightweight design makes it easy to carry for on-site measurements and repairs.
    • Data storage: Includes internal storage for up to 100 sets of multimeter data and 10 oscilloscope waveforms, which can be saved with a single "SAVE" button.
    • Rechargeable battery: Powered by a 1500mAh lithium battery that provides about 6 to 8 hours of use per charge. It also features a low-battery reminder and an automatic sleep function to conserve power.
    • USB-C charging: Uses a modern Type-C port for convenient charging.

        • Square wave: 100Hz to 20kHz.
        • Triangular wave: 100Hz to 50kHz.

    • Output amplitude: Adjustable in multiple steps from 0Vpp to 3Vpp. 

Intended use :

The TOOLTOP ET928 is an ideal tool for users who need the core functions of a benchtop oscilloscope, multimeter, and signal generator in a single, portable, and affordable package. It is well-suited for: 

    • Educational purposes: For students learning basic electronics and signal analysis.
    • DIY electronics projects: Troubleshooting and testing circuit boards.
    • Field technicians: For on-site repairs of home appliances, automobiles, and other electronics. 

Limitations:

While the ET928 is highly versatile for its price point, it's important to be aware of its limitations compared to professional-grade equipment: 

  • Bandwidth: The 12MHz bandwidth is relatively low for measuring high-frequency signals.
  • Single channel: The oscilloscope features only one channel, which limits its ability to analyze relationships between two simultaneous signals.
  • Display: While color, the 2.4-inch screen is small and offers lower resolution compared to dedicated benchtop models.
  • User interface: Some users have reported that navigating the menu for stored data can be tedious.
