Tektronix
award-winning TDS/CSA7000B DPO 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 microvolt-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 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.
This amplifier system delivers versatility to Tektronix high-performance
oscilloscopes through the addition of input coupling (selectable),
bandwidth limit (selectable), 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
and active differential), microvolt differential probes, and current
probes.
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.
