Tektronix has added to to its flagship mixed-signal oscilloscope family; the MSO/DPO70000DX series enhances mixed signal performance and probing capability to 33GHz, and offers upgrade paths as users' needs change

MSO/DPO70000DX oscilloscopes feature models with 23 GHz, 25 GHz, and 33 GHz bandwidth and enhanced tools for debugging digital and analogue circuits. Tek has also announced the fastest and lowest noise oscilloscope probe with 33 GHz bandwidth and highest sensitivity for low-voltage, high-speed serial and RF signals. MSO70000DX mixed signal oscilloscopes span 70MHz up to 33GHz in analogue bandwidth. With 16 digital channels provided on all Tektronix MSO’s, the instruments provide an 80 psec digital timing resolution. This enables engineers to get accurate feedback on logic or protocol performance for serial buses such as USB, I 2C, and SPI in real-time while performing analogue validation of high speed DDR memory on the four high-bandwidth channels.

With the addition of the 33GHz P7600 series TriMode probe Tektronix claims the highest bandwidth probing system on the market. The TriMode probing system gives engineers a single probe setup for differential, single ended and common mode measurements for more value from each scope channel.

“Debugging the latest high-speed serial buses requires high-performance and the flexibility of analogue and digital inputs,” said Brian Reich, general manager, Performance Oscilloscopes, Tektronix. “For engineers working with PCIe3, M-PHY, SuperSpeedPlus USB, and LPDDR3 or DDR4 memory, the 70000DX series delivers the necessary bandwidth along with integrated debugging tools and Visual Trigger.”

Compared to the previous 70000D series oscilloscopes, new MSO/DPO70000DX models offer improved performance and capabilities at overall greater value. The new models offer a variety of upgrade options to preserve investments as needs change including bandwidth upgrades, product conversions and trade-up programs. For example, the analogue-only DPO70000DX versions provide options to add digital channels as needs change via a customer-installable kit.

The MSO models are available with 23 GHz, 25 GHz, and 33 GHz bandwidth and include iCapture simultaneous digital-analogue acquisition capability, unique to Tektronix performance MSOs and logic analysers. This feature allows the engineer to easily and quickly verify the analogue characteristics of any of the
