The DPOF1204 oscilloscope is a digital phosphor four-channel oscilloscope designed for engineers, R&D teams, and production test units requiring deep analysis and high repeatability. Its integrated SoC + FPGA architecture offers 200 MHz bandwidth, sampling up to 1 GSa/s, and memory depth up to 14 Mpts alongside very low noise, enabling precise waveform reconstruction and long-term analysis without resolution loss.
Beyond a general-purpose oscilloscope, the DPOF1204 provides a complete workstation for troubleshooting, validation, and production testing with FFT spectral analysis up to 1M-point, automatic measurements, event search, History/Sequence up to 90,000 records, and serial protocol decoding from I2C to CAN/LIN. The waveform capture rate up to 450,000 wfms/s in Sequence mode and advanced trigger system simplify capturing rare transients and complex conditions.

Practical Applications
Embedded and Mixed-Signal System Debugging: With I2C/SPI/UART decoding and protocol triggering, you can examine startup sequences, ACK/NACK errors, and transient interference alongside GPIO line amplitude and timing. History and event search speed up returning to problematic frames.
Power Supply and Low-Level Signal Validation: 500 μV/div sensitivity and very low noise floor allow observing ripple, loop resonance, and switching noise. With built-in FFT, monitor harmonics and EMI near the source simultaneously, and with deep memory zoom, never miss transient details.
Production Line Testing and Pass/Fail: Define patterns and tolerances, connect Pass/Fail output and Trigger Out to automation systems, and separate defective parts instantly with high capture rate. Sequence Mode with very low Dead-Time covers sporadic events.
Who Benefits Most
Electronics R&D Teams: For digital/analog design verification, timing measurements, and frequency analysis without needing auxiliary tools.
Test and Production Engineers: For fast Pass/Fail tests, high waveform recording, and integration with automation lines via LAN/SCPI.
Automotive and Industrial System Developers: For CAN/LIN analysis, transient interference, and monitoring power supply and sensor stability under varying environmental conditions.
Why Choose This Model
The DPOF1204 offers a balanced combination of 200 MHz bandwidth, deep memory, very high capture rate, and integrated analysis tools (FFT, serial protocols, History/Search). Its SoC+FPGA architecture and low noise floor enable repeatable accuracy in sensitive measurements, while the 7-inch touch screen and 18 one-click shortcuts increase daily work speed. For teams needing an all-in-one time-domain and frequency-domain tool, this device reduces cost and complexity.
Integration and Remote Control
Supporting USB, LAN, Pass/Fail, and Trigger Out, connection to PCs, data logging systems, and production automation is straightforward. SCPI commands and WebControl enable remote control, scripting, and monitoring; thus, you can standardize repetitive test scenarios and collect outputs over the network.
Procurement Process and Included Items
In the box: DPOF1204 unit, four 200 MHz passive probes (FOP-200B), grounding wire, power adapter (US or EU plug), USB-A to USB-B cable, and user manual. Initial setup is quick, and with the touch interface, basic configuration can be done in minutes.
