TekConnect interface delivers superior signal

fidelity, unparalleled versatility, and ease of

use

The TekConnect interface ensures superior signal fidelity with useful

bandpass up to 33 GHz, 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 robust

oscilloscope interface with multi-GHz analog bandwidths. The TekConnect

interface preserves a low Voltage Standing Wave Ratio (VSWR) 50 Ω

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.

TCA75 Adapter (75 to 50 Ω)

The TCA75 adapter allows Tektronix oscilloscopes with a TekConnect

interface to easily access and measure 75 Ω terminated circuitry. The

TCA75 attenuation factor is automatically corrected to provide the end user

with correctly displayed signal magnitudes.

TCA-BNC Adapter (50 Ω only)

A direct 50 Ω input with TekProbe BNC 50 Ω capability, this adapter may

be used as a direct 50 Ω BNC input or with Tektronix high-speed active and

differential probes requiring the TekProbe BNC 50 Ω interface.

TCA-SMA and TCA-N Adapters (50 Ω only)

The high-speed SMA- and N-type adapters allow a more direct connection

to the signal under test requiring N or SMA connections without losing

performance by adding other external conversion adapters.

TCA-292D and TCA-292MM Adapters (50 Ω

only)

These high-speed 2.92 mm-type adapters allow a more direct connection to

the signal under test requiring a 2.92 mm connection without losing

performance by adding other external conversion adapters. The locking

screw must be used to ensure full bandwidth performance. The 2.92 mm

connector is more robust and performs at higher frequencies than an SMA

connector. The 2.92 mm connector is compatible with SMA connectors, but

the electrical performance will be limited to the bandwidth of the SMA

connector.

TCA-1MEG High-impedance Buffer Amplifier

The TCA-1MEG high-impedance buffer amplifier system extends the

capabilities of Tektronix high-performance oscilloscopes, making them ideal

for a variety of general-purpose measurements. The TCA-1MEG amplifier

system provides a 1 MΩ path that is easily removed and replaced with a

wide array of TekConnect probes, amplifiers, and adapters.
