• Compatible with any of the Tabor waveform generators
• Special unipolar mode for MEMS engine drivers (9200A)
Model 9100A/9200A was designed as a
general purpose, wide band and high voltage
amplier however, with specic applications
in mind. It is built in a small case size to save
space and cost but without compromising
bandwidth and signal integrity.
Solve Common Problems
Model 9100A/9200A can output signals
from -200V to +200V with continuous
currents up to 125mA (9200A: 100mA per
channel). The output is driven from a 0.1W
source and, with some degradation of its
bandwidth, can drive capacitive loads up
to 1nF, while maintaining its full amplitude
range. Model 9100A/9200A has a rearpanel monitor output that divides the main
output signal by 100 for applications that
require monitoring of the output signal with
low voltage sensors.
Modes of Operation (9200A only)
The 9200A has two modes of operation. The
rst is normal mode where each channel
amplies and outputs bipolar signals with a
gain of x50. In this mode, the input signal
is amplied and delivered to the output
terminals without modication of its original
properties, except its amplitude level. Using
this mode of operation, each channel can
be used separately to amplify a unique
signal.
The second mode of operation is the
unipolar mode where the signal is applied
to one input, rectied, amplied and output
through two separate outputs. Using
this mode, the amplier is converted to a
one-input, two-output system, specically
designed to operate the up/down and
right/left actuators of a typical MEMS micro
engine, as well as for other applications
requiring the precise conversion of bipolar
to unipolar signals.
Target Applications
The amplier case was designed to stack
on top or below other Tabor products. It
can also be mounted alongside a Tabor
generator in a standard 19" rack. The
waveform-amplier combo is an ideal
solution for virtually any high-voltage, wide
bandwidth application.
Safety
Safety played a major role during the
design of the Model 9100A/9200A. 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 9100A/9200A 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.
