SDS1104X-E 100MHz 4CH Super Phosphor Oscilloscope

Siglent SDS1104X-E 100MHz 4 channel Super Phosphor Oscilloscope, The four channel scope's are available in 100 and 200 MHz and incorporates two 1 GSa/s ADCs and two 14 Mpts memory modules. When all channels are enabled, each channel has sample rate of 500 MSa/s and a standard record length of 7 Mpts. When only a single channel per ADC is active, the maximum sample rate is 1 GSa/s and the maximum record length is 14 Mpts. For ease -of -use, the most commonly used functions can be accessed with its user- friendly front panel design.

The SDS1000X-E series employs a new generation of SPO (Super -Phosphor Oscilloscope) technology that provides excellent signal fidelity and performance. The system noise is also lower than similar products in the industry. It comes with a minimum vertical input range of 500 uV/div, 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-E also employs a 256-level intensity grading display function and a color 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, LIN bus types is included. The X-E models also include History waveform recording, and sequential triggering that enable extended waveform recording and analysis. Another powerful addition is the new 1 million point FFT math function that gives the SDS1000X-E very high frequency resolution when observing signal spectra. The new digital design also includes a hardware co-processor that delivers measurements quickly and accurately without slowing acquisition and front-panel response. The features and performance of SIGLENT’s new SDS1000X-E cannot be matched anywhere else in this price class. The four channel series includes even more functions, including: searching and navigating, on-screen Bode plot, 16 digital channels (Option), an external USB powered 25 MHz AWG module (Option), a USB WIFI adapter (Option), and an embedded application that allows remote control via web browser.

The best value scope in it's category, 4 Channel entry level. I wouldn't say it competes with the Rigol because this one is already preloaded with all the decoding features and doesn't need to be hacked for full bandwidth.

One note, you can't upgrade the bandwidth, not that you would want that for a scope like this, 100MHz is plenty for field usage, debugging microcontrollers, power supplies and audio circuits. And the 4 channels is way more important for more complex measurements.

The only bug I've found is related to triggering, in some rare cases stopping will show multiple trigger results at the same time without persistence being turned on, changing the timebase fixes it.
