MODEL 3180
180Vp-p PXIBus
Signal Amplier
• High voltage output to 180Vp-p (±90V)
• Output current to 150mA
• Large signal bandwidth to 300kHz
• Small signal bandwidth to 1MHz
• Slew rate to 120V/μs
• Selectable gain conguration
• Compatible with any of the Tabor waveform generators

Model 3180 was designed as a general
purpose, wide band and high voltage
amplier, however, with specic applications
in mind. It offers selectable gain of up to
x50, with amplitudes of -90V to +90V and
an output current of 150mA. With a large
signal bandwidth of up to 300kHz and a
small signal bandwidth of up to 1MHz the
new 3180 offers new possibilities to meet
the requirements that couldn’t be met before
in a PXI form format, without compromising
bandwidth and signal integrity.
Solves Common Problems
A common problem with PXI equipment
is the inability to produce high voltages
resulting from low power supply rails. For
example, waveform generators or similar
signal source devices draw power from 12V
rails. Consequently, they cannot produce
signals above 10Vp-p into 50Ω. Model
3180 solves this problem by using DC/DC
converters to increase rail voltages which,
along with custom components and unique
design, enable amplication of input signals
to 180Vp-p into 0.1Ω.

Safety
Safety played a major role during the design
of the model 3180. The high voltage path
to the amplier circuit is blocked by a front
panel mechanical switch and accidental
application of high power to the UUT is
prevented by a safety latch. The 3180 will
output high voltage signals only after the
safety latch has been lifted and the high
voltage switch ipped to ON position. In
emergency situations, one can hit the
protective latch to immediately remove the
high voltage power from the output terminals.
As an additional visual safety feature, a red
light glows on the front panel whenever the
high voltage is turned on.
Allows Full Current Rating to Other Devices
The power amplier draws current only
from the ±12, and +5V rails, leaving the
other power supply rails free to supply their
full current rating to other devices.

Target applications
Although the model 3180 wideband amplier
occupies a single slot, its performance is
unique and outstanding by any standards.
With 180Vp-p and over 300kHz bandwidth
one can use model 3180 for virtually any
application. A common application is in the
automotive industry, where 28V or more
is needed, but for others, like the defense
and aviation industries, where even higher
levels are required, the 3180 is a must.
Cost effective solution
Model 3180 is a cost-effective, versatile
power amplier that opens the door
to numerous applications, specically
implemented with PXI equipment.
