Siglent SDS1104X-U Super Phosphor Oscilloscope

The SDS1104X-U is a 4CH, 100MHz Super Phosphor Oscilloscope and has a maximum sample rate of 1GSa/s and a maximum record length of 14Mpts. For ease-of-use, the most commonly used functions can be accessed with its user-friendly front panel design. The SDS1000X-U series employs the well-known SPO (Super -Phosphor Oscilloscope) technology that provides excellent signal fidelity and performance. It comes with an innovative digital trigger system with high sensitivity and low jitter, and a waveform capture rate of 400,000 frames/sec (sequence mode). The SDS1000X-U also employs a 256-level intensity grading display function and a colour temperature display mode not found in other models in this class. SIGLENT’s latest oscilloscope offering supports multiple powerful triggering modes including serial bus triggering. Serial bus decoding for IIC, SPI, UART, CAN, and LIN bus types are included. The X-U models also include History waveform recording and sequential triggering that enable extended waveform recording and analysis. Another powerful addition is the new 128k point FFT math function that gives the SDS1000X-U very high frequency resolution when observing signal spectra. The digital design includes a hardware co-processor that delivers measurements quickly and accurately without slowing acquisition and front-panel response. SDS1000X-U also supports searching and navigating. The features and performance of SIGLENT’s new SDS1000X-U cannot be matched anywhere else in this price class
