Langer EMV-Technik has launched the PA 306 SMA set, with a preamplifier frequency range from 100 kHz to 6 GHz that can be utilized for amplifying measurement signals, for example weak signals from high-resolution near-field probes or antennas. It is characterized by low noise output and a high dynamic scope over a wide frequency range.

The PA 306 is connected to the 50 Ω input of a spectrum analyzer or oscilloscope. The power supply to the PA 306 is via the plug-in power supply unit. A near-field probe is connected with the corresponding cable to the input of the preamplifier.
