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, ma king them ideal
for a variety of general-purpose mea s ureme nts. 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 ada pters.
This amplifier system delivers versatility to Tektronix high-performance
oscilloscopes through the addition of input coupling (selectable), band width
limit (select
able), and a 1 MΩ input that provides access to a wide array of
measurement solutions. These solutions include general-purpose passive
probes, high-voltage probes (passive single-ended an d active differential),
microvolt differential probes, and current probes.
With this to ol, Tektronix high-pe rformance oscilloscopes may now perform
measurements such as primary and seco ndary power supply voltage levels,
currents, and elevated voltages, and assess th e powe r requirements of
the device-under-test.
For today's high-speed measurement solutions, having the 50 Ω and1MΩ
terminations on the same input path compromises signal fidelity. By making
the 1 MΩ path
replaceable, the TCA-1M EG high-impedance buffer amplifier
system eliminates a permanent degradation of the high-speed signal path.
This also allows users to easily and quickly confi gure each channel for the
input characteristics required for their measure m ents. By exchanging the
TCA-1MEG for a high-performance 50 Ω path or other high-speed probing
solution, maximum signal fidelity is ma intained at the oscilloscope's input.

Interface Delivers Superior Sig nal
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
versatili
ty 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 inte rfaces. The TekConne ct interface
preserves a low-voltage sta nding wave ratio (VSWR ) 50 Ω environment as
well as a re
liable electrical connection. A c onvenien t, one-button release
and locking mechanism provides quick, easy installation and removal of
probes, amplifiers, and adapters.
