1 Introduction
1.1 Device Description
The A1230-02 is a linear, extremely wideband precision power amplifier. It is ideal for all
applications that require fast changing signals at any purely resistive and complex loads.
The A1230-02 has two summable inputs per channel with 50 Ω and 100 kΩ input resistance; the
50 Ω input makes it the ideal downstream equipment for conventional function generators.
Two optional operating voltages are available for high-voltage/low-current or low-voltage/high-
current applications. Especially in case of very low-impedance loads, choosing the low operating
voltage leads to a considerable reduction of the power loss and a higher output current.
If higher output voltages are required, the preamplifier output ( Bridge Out ) allows a simple set-up
of a bridge circuit with the second channel of the A1230-02 for doubling the output voltage.
Use the plug-on adapter box to easily connect both channels in parallel if more current is required.
Operation with equal output signals is strictly required in this setup.
The device is equipped with a temperature-controlled, low noise fan. It also features an over-
temperature protection. A power-loss calculation and an absolute-current monitoring guarantee
perfect short-circuit and overload protection. The operation is implemented over the operating
elements on the front panel. In addition, the amplifier is fully remote controllable via the USB port
using a simple byte protocol.
If even higher output voltages or higher output currents are required, configurations with series or
parallel connections of several A1230-02 are possible.
