Introduction：
The PA 2522 is a high-frequency, low-noise preamplifier manufactured by LANGER and distributed by EUTTEST in Shenzhen, China. The PA 2522 is used to improve the signal-to-noise ratio of near-field probes. For normal use, we have configured the PA 2522 with a power adapter to supply power and form the PA 2522 SET.
The PA 2522 should be connected to the 50 Ω input of a spectrum analyzer or oscilloscope. The preamplifier is powered by the power adapter, which is included in the chassis. For example, the PA 2522 can be used to amplify the measurement signal of a Langer near-field probe. For this purpose, a near-field probe with a suitable frequency range and corresponding cable should be connected to the input of the preamplifier.
