Hantek DSO2D20 Series 200–500MHz Digital Oscilloscopes

The Hantek DSO2D20 Series combines six 2-channel digital oscilloscopes with 200MHz, 350MHz or 500MHz analog bandwidth. Every model provides a maximum 2GSa/s single-channel sample rate, 80Kpts single-channel memory and a 7-inch 800×480 display for electronics development, service diagnostics, education and embedded-system debugging.

Choose a C model for oscilloscope-only measurements or the corresponding D model when a built-in 1-channel 25MHz arbitrary/function generator is required. This paired model structure makes it possible to match both bandwidth and stimulus-generation needs without paying for an unused function.

Key Features

• 200–500MHz bandwidth choices: Select the analog bandwidth that matches the edge rates and frequency content of the signals under test.
• 2GSa/s maximum sampling: Captures waveform detail at the maximum single-channel sample rate; the all-channel sample rate is 1GSa/s.
• 80Kpts acquisition memory: Stores up to 80Kpts in single-channel operation or 40Kpts with all channels active.
• 2-channel input: Compares related analog signals such as input and output, clock and data, or voltage across two circuit nodes.
• 2,000wfms/s capture rate: Supports responsive observation of changing and intermittent signal behavior.
• Serial bus analysis: Triggering and decoding support for UART, LIN, CAN, SPI and IIC buses assists embedded-system troubleshooting.
• Flexible input termination: Switchable 1MΩ and 50Ω input impedance supports common probing and signal-source connections.
• Integrated AFG on D models: A 1-channel 25MHz, 200MSa/s, 12-bit generator with 4K waveform length provides stimulus and measurement in one instrument.

Model Differences & Selection

• DSO2C20: 200MHz scope-only model for general electronics, education and routine debugging.
• DSO2C35: 350MHz scope-only model for faster digital and mixed-signal circuit work.
• DSO2C50: 500MHz scope-only model for signals requiring the highest bandwidth in this six-model group.
• DSO2D20: Adds the built-in 25MHz AFG to the 200MHz oscilloscope platform for combined stimulus and response testing.
• DSO2D35: Combines 350MHz oscilloscope bandwidth with the 25MHz AFG for mid-band development and verification.
• DSO2D50: Combines 500MHz oscilloscope bandwidth with the 25MHz AFG for higher-frequency stimulus-and-measurement workflows.

Applications

• Embedded controller and serial bus debugging
• Analog, digital and mixed-signal circuit development
• Power-supply ripple, timing and transient observation
• Electronics repair, maintenance and service diagnostics
• Laboratory instruction and engineering education

Why Choose the Hantek DSO2D20 Series?

The six-model structure provides a direct choice between three bandwidth levels and two functional configurations. C models focus on waveform acquisition, while D models add a built-in signal source for engineers who need to excite a circuit and observe its response from the same bench instrument.
