TekConnect™High-impedance Buffer Amplifier System

TCA-1MEG

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 family of amplifiers, probes
and adapters make it the ideal solution for
such challenges, delivering a variety of acqui­sition capabilities through the use of existing
compatible TekConnect and TEKPROBE
measurement tools.

TekConnect TCA-1MEG Buffer
Amplifier System Expands the
Functionality of Tektronix
High-performance
Oscilloscopes

The TCA-1MEG high-impedance buffer
amplifier system extends the capabilities of
Tektronix high-performance oscilloscopes,
making them ideal for a variety of general­purpose 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.

This amplifier system delivers versatility to
Tektronix high-performance oscilloscopes
through the addition of input coupling (selec­table), bandwidth limit (selectable), and a
1MΩ input that provides access to a wide
array of measurement solutions.These
solutions include general-purpose passive
probes, high voltage probes (passive single­ended and active differential), micro-volt
differential probes and current probes.

TekConnectTMHigh-impedance Buffer Amplifier System

TCA-1MEG

With this tool,Tektronix high-performance
oscilloscopes may now perform measure­ments such as primary and secondary power
supply voltage levels, currents and elevated
voltages, and assess the power requirements
of the device-under-test.

For today’s high-speed measurement solutions,
having the 50 Ω and 1 MΩ terminations on
the same input path compromises signal
fidelity.By making the 1 MΩ path replaceable,
the TCA-1MEG high impedance buffer amplifier
system eliminates a permanent degradation of
the high-speed signal path.This also allows
users to easily and quickly configure each
channel for the input characteristics required
for their measurements. By exchanging the
TCA-1MEG for a high-performance 50 Ω
path or other high-speed probing solution,
maximum signal fidelity is maintained at the
oscilloscope’s input.

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

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 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.
