Advanced 12-Bit Resolution for Accurate Signal Measurement

Unlike conventional 8-bit oscilloscopes, the RIGOL DHO914S features a high-resolution 12-bit ADC architecture that delivers significantly improved waveform clarity and signal precision. With 4096 quantization levels, engineers can detect small voltage variations, reduce measurement uncertainty, and analyze low-amplitude signals with superior accuracy.

The ultra-low noise floor helps capture cleaner waveforms, making the oscilloscope ideal for sensitive electronic measurements, power analysis, analog circuit testing, and precision embedded applications.

High-Speed Waveform Capture and Deep Memory

The DHO914S oscilloscope provides an impressive waveform capture rate of up to 1,000,000 waveforms per second in UltraAcquire mode. This enables engineers to quickly detect intermittent glitches, rare signal anomalies, and transient events during troubleshooting and debugging.

With up to 50 Mpts memory depth, users can capture long-duration waveforms while maintaining high sample resolution. This allows detailed waveform analysis without losing critical signal information.

Built-In Arbitrary Waveform Generator (AWG)

One of the major advantages of the RIGOL DHO914S is its integrated 25 MHz arbitrary waveform generator. The built-in AWG enables users to generate custom test signals directly from the oscilloscope without requiring additional external equipment.

This functionality is extremely useful for:

• Signal simulation
• Circuit response testing
• Educational demonstrations
• Embedded system verification
• Communication signal analysis
• Frequency response and Bode plot testing

Mixed Signal Analysis Capability

The DHO914S supports optional 16 digital logic channels using the PLA2216 logic probe, transforming the oscilloscope into a mixed signal oscilloscope (MSO). This allows simultaneous analysis of analog and digital signals, making it highly suitable for embedded system debugging and digital circuit design.

Supported serial bus decoding includes:

• I2C
• SPI
• UART/RS232
• CAN
• LIN

These advanced decoding functions simplify communication protocol analysis and troubleshooting in automotive electronics, IoT devices, industrial controllers, and embedded applications. (TestEquity)
