The Rigol DS70504 is a 5 GHz, 4-channel digital oscilloscope engineered for signal integrity testing, high-speed digital design, and research applications. Built on the UltraVision III platform with Phoenix chipset architecture, this instrument delivers 20 GSa/s real-time sampling, hardware-accelerated FFT analysis up to 10,000 frames/s, and waveform capture rates exceeding 1,000,000 wfms/s. It functions as a digital oscilloscope, real-time spectrum analyzer, digital voltmeter, 8-digit frequency counter, and protocol analyzer—making it suitable for complex multiprotocol environments.
