50GHz, 23GHz models expand oscilloscope family

The 23GHz instrument joins the existing 33GHz models which feature compact dimensions and built-in scalability using the UltraSync synchronisation technology.

As speeds go up and amplitudes go down, system noise has become a major challenge because it obscures important details in signal behaviour. Tektronix’ 50GHz and 70GHz ATI oscilloscopes allow engineers to more accurately capture and measure higher frequency signals with up to 30% less system noise than the legacy frequency interleaving approaches used by other oscilloscope manufacturers.

Current real time scope solutions for digitising ultra-high bandwidth signals distribute signal energy to two digitising paths then use DSP to reconstruct the input signal. Unlike legacy schemes, Tektronix' unique ATI architecture uses a symmetrical technique that delivers all signal energy to both digitising paths resulting in an inherent noise advantage when signals are reconstructed.

The 50GHz instrument’s ATI channel offers 200GS/s sample rate for 5ps/sample resolution. It also has two standard (non-ATI) 33GHz channels with 100GS/s sample rate for 10ps/sample resolution.

To further enhance signal fidelity, the oscilloscopes use a compact 5 1/4 inch form factor so the instrument can be positioned very close to the device under test (DUT) for shorter cable lengths and cleaner signals.

The low height means each unit fits in a single 3U rackmount space, or two oscilloscopes can be stacked in the same space as a single standard bench oscilloscope.

Precise multi-instrument timing synchronization is required for test applications such as validation of high-speed networking technologies used in long-reach fibre systems (DP-QPSK Coherent Modulation) and shorter-reach (PAM4) data centre networks. The DPO70000SX oscilloscopes meet these needs through the patent-pending UltraSync architecture that provides precise data synchronisation and convenient operation of multi-unit systems. UltraSync uses a 12.5 GHz sample clock reference and coordinated trigger for inherent channel-to-channel skew stability superior to channels within a single instrument.
