  Description

TekConnect Interface Delivers Superior Signal Fidelity, Unparalleled Versatility, and Ease-of-Use

Tektronix award-winning TDS7000, CSA7000, and TDS6000 Series oscilloscopes allow engineers to make high-speed measurements quickly and efficiently. In addition to these high-speed measurements, many of today's designers also face the challenges of measuring high voltage, current, power, or even micro-volt level signals to gain a more complete understanding of their designs.

The TekConnect interface ensures superior signal fidelity with useful bandpass up to 18 GHz at the oscilloscope input, while offering unparalleled versatility with the world's widest array of accessory signal acquisition solutions for high-performance, real-time oscilloscopes. This interface delivers a more robust oscilloscope interface for next-generation products with multi-GHz analog bandwidths, overcoming many of the inherent bandwidth limitations of BNC-based interfaces. The TekConnect interface preserves a low voltage standing wave ratio (VSWR) 50 O environment as well as a reliable electrical connection. A convenient, one-button release and locking mechanism provides quick, easy installation and removal of probes, amplifiers, and adapters.

TekConnect TCA Series Adapters Expand the Functionality of Tektronix High-performance Oscilloscopes

This family of adapter systems provides less signal distortion and better performance than traditional connections used to move a signal from one environment to another, such as BNC to N or BNC to SMA.

TCA75 Adapter (75 to 50 O)

The TCA75 adapter allows Tektronix oscilloscopes with TekConnect interface to easily access and measure 75 O terminated circuitry. The TCA75's attenuation factor is automatically corrected to provide the end user with correctly displayed signal magnitudes.
