TDS 400A Personal Lab
Oscilloscopes

For professionals who
demand high precision and
fidelity from their measure­ments, the TDS 400A Per­sonal Lab Scopes combine
excellent performance and
broad feature set, all at
affordable prices. A choice of
2 and 4 channel models rang­ing from 200 MHz to 400
MHz with a 100MS/s sample
rate on all channels makes
the TDS 400A Series a wor­thy fit for a variety of
demanding applications.

The highly featured, portable,
and easy to use TDS420A,
430A and 460A personal lab
scopes are ideal for simple to
complex applications,
including electro-mechanical
research and analysis, power

electronics/power supply
design, bio-physical research
and analysis, digital and
analog design. With its stan­dard video trigger capability,
the scopes are ideal instru­ments for measuring video
signals including NTSC, PAL
and SECAM.

The TDS 400A Series uses the
renowned TDS Graphical
User Interface which offers
intuitive icon-based menus
along with help text, making
scope operation extremely
simple. Knobs and buttons
allow easy selection of com­monly used scope functions.
The standard floppy disk
drive makes the saving of
screen images or data to a disk
simple. The disk can then be
inserted into your PC for
importing to desktop publish­ing or spreadsheet programs.

one or more acquisitions, selectable from
2 to 2000, infinite.

Average – Waveform averages selectable
