Short description
The PA 303 SMA preamplifier is designed for the amplification of measuring signals, e.g. weak signals of near-field probes with high resolution. The input and the output of PA 203 use either a 50 ohm BNC (PA 303 BNC) or SMA connector (PA 303 SMA).
PA 303 is connected to the 50 ohm input of a spectrum analyzer or an oscilloscope. The power plug ensures the power supply of the PA 303. The near-field probe is connected via the respective cable to the input of the preamplifier.
