The PA203 preamplifier is used to amplify measurement signals, eg weak signals from high-resolution near-field probes. The input and output of the PA203 are designed as 50 Ω BNC.
The PA203 preamplifier is connected to the 50 Ω input of a spectrum analyzer or oscilloscope. The plug-in power supply ensures the supply of the PA203. The near field probe is connected to the input of the preamplifier with the appropriate cable.
