The PA 2522 preamplifier from Langer EMV-Technik GmbH provides meaningful measurement results, even with low input signals. 

Obtaining informative results from an EMC measurement often fails because the measurement levels are too low or because the measurement tools used are not sensitive enough. Support is now offered by the PA 2522 preamplifier with its amplification of 25 dB.

The PA 2522 amplifies low measurement signals over an extremely wide frequency range, from 10 MHz to 22 GHz, with very low noise and a constantly high dynamic range. This means that sources of interference with very low levels can now be clearly detected on measuring equipment. 

The signal amplifier, which is handcrafted in Germany, is a consistent further development  for  EMC  applications. In combination with a matching near-field  probe, e.g. from Langer EMV-Technik, it is possible to perform harmonic measurements of high frequency signals up to 22 GHz. 

With its compact design, the PA 2522 can be integrated into development environments in a versatile way. Directly connected to the 50 Ω input of a spectrum analyzer or oscilloscope the preamplifier simultaneously protects sensitive measuring equipment from overvoltage. 

The PA 2522 is powered by the supplied plug-in power supply.
