Oscilloscopes Deliver 100GS/s Sampling Rates

Tektronix has announced the DPO/DSA/MSO70000C Series of digital and mixed signal oscilloscopes to offer more accurate signal integrity measurements for high-speed serial standards. These devices now deliver 100GS/s sampling rate performance; enabling lower noise along with increased data points on 5x over-sampled 20GHz acquisitions. High-performance oscilloscopes with a bandwidth greater than 4GHz are used in a variety of high-speed serial, wideband radar, fast optical communications systems, high-end embedded systems and high-energy physics applications.

The DPO/DSA/MSO70000C Series can provide the performance and signal fidelity designers need to ensure that their latest components and systems meet design specifications. Along with a two-fold increase in sampling rate compared to the 'B' Series it replaces, the DPO/DSA/MSO70000C Series features a faster compute platform. This new platform offers faster processing for longer data records such as jitter, noise, BER (bit error rate) measurements and statistics. Boot and application start-up times are also much quicker.

In any digital oscilloscope, there is a strong correlation between sampling rate and internal noise - a high sampling rate results in less noise, which in turn leads to more margin for the user. As shown by comparison testing, the DPO/DSA/MSO70000C Series with 100GS/s operation delivers up to 20 per cent reduction in noise compared to the 50GS/s setting on the same instrument. Modern radar designs use frequency and phase modulation within the radar pulses to increase a radar's range resolution and target identification capabilities. Maintaining the same modulation characteristics from pulse to pulse is key to the system's operation.

Performance oscilloscopes are the tool of choice for radar pulse measurement, but must have a stable timebase able to stay on frequency for long captures. The DPO/DSA/MSO70000C Series meets this requirement with a new high-stability timebase that provides for lower long-term jitter, phase and frequency stability. When combined with the pulse and frequency settling measurement capabilities of SignalVu vector signal analysis software, the DPO/DSA/MSO70000C Series gives designers of frequency agile radios and radars the ability to accurately verify system performance.

The DPO/DSA/MSO70000C Series oscilloscopes provide the bandwidth and sampling rates needed to debug serial data signals up to 12Gb/s on all channels simultaneously - ideal for multi-lane applications including PCI Express 3, SATA 6Gb/s, Superspeed USB, HDMI, Displayport and 10Gb Ethernet. The Fastacq acquisition mode provides a capture rate greater than 300,000 waveforms per second - delivering both critical insight into signal behaviour and in-depth analysis.
