PA 2522
Preamplifier 10 MHz up to 22 GHz
Short description
The PA 2522 preamplifier is used to amplify weak measurement signals, e.g. from near-field probes. It is characterized by low noise behavior and a constantly high dynamic range over a very wide frequency range.
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 case. The PA 2522 can be used, for example, to amplify the measurement signals of the Langer near-field probes. To achieve this, a near-field probe with a suitable frequency range and corresponding cable should be connected to the input of the preamplifier.
