Fnirsi DST-210 Handheld 3-in-1 Digital Oscilloscope, Multimeter and DDS Signal Generator, 10MHz Bandwidth, 48MS/s

The Fnirsi DST-210 is a compact, handheld 3-in-1 measurement instrument that integrates a digital oscilloscope, a high-precision multimeter, and a DDS signal generator into a single portable unit. Designed for versatility, this device provides essential diagnostic capabilities for electronics professionals, students, and hobbyists who require a reliable tool for field work or laboratory testing.

Advantages

This device offers significant space and cost efficiency by combining three distinct testing tools into one lightweight housing. The inclusion of a 19999-count multimeter ensures high-resolution measurements, while the 10 MHz bandwidth and 48 MS/s sampling rate provide sufficient performance for analyzing common electronic signals. Its portable design, supported by a long-lasting 3000 mAh battery and modern USB Type-C connectivity, makes it an ideal solution for technicians who need to perform measurements in various locations without constant access to a power outlet.

Suitable for

• General electronics repair and troubleshooting
• Educational laboratory experiments
• Signal analysis and circuit testing
• Field maintenance of electronic equipment

When it may not be suitable

This device is not intended for high-frequency signal analysis or complex industrial applications requiring bandwidths exceeding 10 MHz. It may also be less suitable for users who require multi-channel oscilloscope capabilities, as this model is designed for single-channel signal monitoring.

Key specifications

• Bandwidth: 10 MHz
• Sampling rate: 48 MS/s
• Multimeter resolution: 19999 counts
• Display: 2.8-inch TFT
• Battery capacity: 3000 mAh
• Interface: USB Type-C
• Vertical sensitivity: 10 mV/div

How to use

To begin using the device, ensure the battery is charged via the USB Type-C port. Select the desired mode—oscilloscope, multimeter, or signal generator—using the intuitive interface controls. Connect the appropriate probes to the input terminals based on the measurement type required. For oscilloscope functions, adjust the vertical and horizontal scales on the TFT display to capture and analyze the waveform effectively.

What to consider before purchase

• Verify that the 10 MHz bandwidth is sufficient for your specific signal analysis needs.
• Consider whether a single-channel oscilloscope meets your project requirements.
• Ensure the device dimensions and weight align with your portability needs.

Usage recommendations: Always inspect the probes for damage before use and ensure the device is set to the correct measurement mode to prevent damage to the internal circuitry. Store the unit in a dry environment when not in use to maintain battery health and display clarity.
