Langer EMV-Technik to Unveil New Near-Field Probe and Preamplifier at DesignCon 2022
Langer EMV-Technik has announced that they will be showing two products: the HR-E 40-1, a passive near-field probe, and PA 2522, a preamplifier at DesigCon 2022.
The HR-E 40-1 is a passive near-field probe for measuring electric fields up to 40 GHz. The measuring electrode of the probe has a diameter of 0.25 mm and can resolve objects (RF traces) in this range. The probe is placed vertically and centrally on the RF trace for measurement. By placing the probe directly on the RF trace, a defined distance (0.5 mm) between the RF trace and the measuring electrode is achieved. The measuring tip is decoupled from the cable shield by special damping systems.
PA 2522 is a preamplifier used to amplify weak measurement signals, e.g. from near-field probes. It is unique because of its low noise behavior and a constantly high dynamic range over an extremely wide frequency range (10 MHz to 22 GHz).
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.
