The 34980A implements a
superior selection of switch
topologies. The 34980A switch
topologies are similar to
3499A/B/C switch modules and
include multiplexers, matrixes,
high-power, general purpose, and
RF/microwave switches.
However, the 34980A modules
have utilized the newest switch
technology which enables a higher
density of channels per module,
and the ability to achieve the
faster scan rates with the
integrated DMM. The 34980A
offers other functionality used in
test systems and includes digital
I/O, a counter/totalizer and D/A
converters. New 34980A
functions include a FET
multiplexer switch module, a
counter/timer and digital I/O with
pattern generator/detector along
with digital I/O and D/A
converters. The 34980A RF and
microwave switch drivers offer
functionality for a broader range
of RF/microwave switches being
used by customers today.
The 3499A/B/C does provide a
selection of optics switching
which is not available with the
34980A. Table 2 shows the
34980A and 3499A/B/C system
modules organized by switch
and/or measurement type. It is
easy to compare and upgrade
from the 3499A/B/C switch
modules to the new 34980A
switch modules as well as add
new switch, measurement and
control capabilities.
Benefits of the new 34980A
modules vs 3499A/B/C modules
• Increased channel count per
module with the same switch
reliability
• Increased drivability for
various RF/uWave switches
• High Speed FET multiplexer
• Reed Matrix switch
• Switch/attenuator driver
• Counter/Timer
• High Speed Digital I/O with
memory
• Analog output with waveform
capabilities
• Breadboard module
with +5V, +12V
With so many different types of
switch modules to choose from,
you can easily identify the
modules from Table 2 that
provide the best solution to meet
your test application needs. For
