Compact amplifier module
In modern optoelectronic systems lock-in-amplification is one of the most useful techniques to get rid of unwanted noise and to improve the measurement sensitivity. Therefore we have created a miniaturized, powerful module operating reliably even in heavy noise environments.
Two Ways of Programming
The amplifier settings - e.g. phase, gain, time constant - are controlled either by switches
directly on the amplifier module or externally using a standard digital
Applications
