SA-600 Series is a
wideband current amplifier (current to voltage converter) with a high gain
and wide frequency band. There are the following four types depending on the
gain.
It operates stably for the added input capacitance despite a wide frequency
band. It operates without oscillation with an added input capacitance of 1000 pF. The LPF cutoff
frequency can be selected from four steps with a switch.

High Gain and Broad Bandwidth
SA-600 series support 4 types of gain as
10 M/100 M/1 G/10 G (V/A). With high-gain, they realize broader bandwidth
than the conventional products.
Gain-frequency characteristics
Stable to Capacitance of Sensors and Connecting Cables
Regardless of broad frequency band, the SA-600 series operates stably
for additional input capacitance of sensors and connecting cables,
eliminating any concerns about oscillation. Thus almost no overshoot and ringing occur for the pulse response. With its
stability, the SA-600 series enables safely use to variety of sensors.
Low Noise
Not only high gain and broadband,
the SA-600 series also achieves a low noise of fA (10-15) order.
The SA-600 series adopts SMA connectors for
input and output with excellent shielding characteristics.
In addition, as the power supply, we also provide the low noise DC power
supply that reduces the output noise to the level of 10 μVrms or less, enabling accurate signal processings of small power.

LPF Output
The SA-600 series is equipped low-pass filter (LPF)
output, enabling the output with the limited bandwidth. you can change the
cut-off frequency on the panel.
Cut-off frequency is easily set, using the switch on the panel
(4 points selectable).
