Tektronix Extends Bandwidth on Mixed Signal Oscilloscopes
The new MSO/DPO70000DX Series of performance oscilloscopes from Tektronix features models with 23GHz, 25GHz, and 33GHz bandwidth and enhanced tools for debugging digital and analogue circuits. The company also announced the world’s fastest and lowest noise oscilloscope probe with 33GHz bandwidth and industry leading sensitivity for low-voltage, high-speed serial and RF signals.
These mixed signal oscilloscopes expand Tektronix's portfolio of MSO’s from 70MHz up to 33GHz in analogue bandwidth. With 16 digital channels provided on all Tektronix MSO’s, engineers can connect and observe a greater amount of their design’s electrical behaviour at one time. This shortens debug cycles and system validation. The instruments provide an 80ps timing resolution on the 16 digital channels. This enables accurate feedback on logic or protocol performance for serial buses like USB, I2C, and SPI in real-time while performing analogue validation of high speed DDR memory on the 4 high-bandwidth channels.

The addition of the 33GHz P7600 series TriMode probe gives engineers a single probe setup for differential, single ended and common mode measurements for more value from each scope channel.

Compared to the previous 70000D series oscilloscopes, new MSO/DPO70000DX models offer improved performance and capabilities at overall greater value. The new models offer customers a variety of upgrade options to preserve investments as needs change including bandwidth upgrades, product conversions and trade-up programmes. 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 23GHz, 25GHz, and 33GHz bandwidth and include iCapture simultaneous digital-analogue acquisition capability. This feature allows the engineer to easily and quickly verify the analogue characteristics of any of the 16 signals connected to the MSO70000DX series' digital channels without changing probes or connections.

Both the MSO and DPO models in the new series feature wider dynamic range of 600mV/div (6V full scale) at maximum voltage setting, five times more than the 70000D series. Record length is now four times as long at 1Gsamples/channel on two channels. Processor speed has also been improved which enables faster decode on longer records. In addition, the instruments support a more than 300,000 wfms/s acquisition rate.
