As digital speeds and device complexity continue to increase, signals under test are getting more complex, and engineers are more challenged to isolate anomalies in their devices. Test tools for such applications require wide dynamic range measurements to look at minimal signals in the presence of relatively large amplitudes. The new high-resolution SDS2000X HD series of oscilloscopes from SIGLENT, represented by Comtest, are available in bandwidths of 100, 200 and 350 MHz. They are based on a new 2 GSa/s, 12-bit ADC front end that features an exceptionally low noise floor, providing more signal detail and enabling engineers to obtain more accurate waveform measurements.
The vertical resolution of an oscilloscope refers to the ratio of the highest input signal the oscilloscope can handle to the smallest signal amplitude it can detect. With higher resolution measurements, waveform details become more visible, quantisation noise is reduced, and measurement accuracy improves.
The Siglent SDS2000X HD series is a next-generation oscilloscope featuring a 12-bit ADC and a low-noise front-end, providing 16 times the signal resolution of a traditional 8-bit oscilloscope. The SDS2000X HD series displays signals with greater detail, makes more precise measurements, offers higher voltage offsets, and provides better accuracy than traditional 8-bit oscilloscopes.
The SDS2000X HD series also includes several time-saving features. They include deep memory with a maximum record length of 200 Mpts/ch and display four analogue channels and an optional 16 digital channels for mixed signal analysis. They employ Siglent’s SPO technology with a maximum waveform capture rate of up to 100 000 wfm/s (up to 500 000 wfm/s in Sequence mode), 256-level intensity grading display function, plus a colour temperature display mode.
SDS2000X HD also employs an innovative digital trigger system with high sensitivity and low jitter. The trigger system supports multiple powerful triggering modes, including serial bus triggering. An impressive array of measurement and math capabilities, options for a 25 MHz arbitrary waveform generator and serial decoding are also features of the SDS2000X HD.
The SIGLENT SDS2000X HD 12-bit oscilloscope is ideally suited for power supply designers or systems where accuracy and resolution are critical. It is an ideal solution for these test parameters.
