Working Principle:
Analog signals are digitized by a high-speed 8-bit A/D converter at up to 5 GS/s. The digital data is stored in deep memory and processed by an FPGA-based acquisition engine for real-time waveform display, triggering, and measurements. The 16 digital channels are sampled synchronously with the analog channels via a dedicated logic acquisition ASIC, enabling correlated analog-digital analysis (e.g., observing an SPI command and the resulting analog response simultaneously). Serial bus decoding (I2C, SPI, UART, CAN, LIN, I2S, RS-232C) is performed in real-time by the FPGA, displaying decoded data overlaid on the waveform.
Advantages & Highlights:
- Only oscilloscope in its class with 16 digital channels + 4 analog channels simultaneously
- 500 MHz bandwidth with 5 GS/s sample rate — excellent for high-speed digital and power electronics
- Built-in serial bus decoder for 8 protocols (I2C, SPI, UART, CAN, LIN, I2S, RS-232C, Parallel) — no extra cost
- 500 Mpoint memory depth captures long-duration events at high sample rate
- History function: store up to 40,000 waveforms for before/after comparison
Applicable Industries:
- Automotive electronics (ECU testing, CAN/LIN bus analysis)
- Embedded system development and debug
- Power electronics (inverter, converter, motor drive analysis)
- Aerospace and defense electronics
- Education and research laboratories
Installation Requirements:
- Place on a stable, vibration-free benchtop
- Ensure minimum 100 mm clearance on all sides for ventilation
- Connect to AC mains with a grounded 3-prong outlet
- Use 50 Ω terminated coaxial cables for high-frequency signals (> 100 MHz)
Usage Precautions:
- Do not exceed the maximum input voltage: 300 V (DC + AC peak) for all channels
- For signals above 300 V, use a high-voltage probe (rated for the voltage)
- Do not connect the ground clip to a point other than circuit ground (creates short circuit)
- Allow 30-minute warm-up for best measurement accuracy
- Use 1:1 probe setting for low-frequency signals to maximize bandwidth utilization
