This unit is a version of A400 amplifier equipped with two inputs, DC-offset and output attenuation.
A DC level, adjustable within 0…+10V range, is provided on the front panel from two BNC contacts marked “OFFSET OUT”. Both contacts are internally connected to simplify monitoring of the output. For bipolar operation the DC level should be supplied to ±B input. Please note that the maximum total amplitude of superposed A and B signals should stay within ±10V range, otherwise clipping will occur.
Output attenuation by means of dedicated switch the output can be attenuated 100 times (-40dB) for safe handling.
The A400X is a general purpose broadband linear amplifier having a fixed amplification of 20 times and capable of bipolar high voltage output of ±200V.
Any function generator or arbitrary waveform generator or any other signal source with amplitude up to ±10 V can be used as an input device.
The amplifier’s output is linear from DC up to megahertz range.
It can be used in a wide range of applications, for example to drive piezo actuators, MEMS, OLEDs, liquid crystals, etc.
