Overview
The Radiation Source RS 9244 corresponds to the requirements of the standard CISPR 25 Edition 4.
The title of the Standard is: ALSE Performance Validation 150 kHz – 1 GHz.
The radiation source RS 9244 complies to CISPR 25 Edition 4, which proposes the "Long Wire Antenna" and is used as reference source to evaluate the suitability of absorber lined shielded enclosures (ALSE) according to the 'Long Wire Antenna method'.
The RS 9244 consists of an 500 mm long horizontal brass rod with an diameter of 4 mm. This brass rod is held by two aluminium brackets at a height of 50 mm above an aluminium ground plane. The size of this ground plane is 150 mm x 700 mm.
For the "long wire antenna method" a 10 dB (50 Ohm) attenuator (eg. Schwarzbeck DGA 9552 N) and a 90° angle connector between the source cable an the RS 9244 is neccessary.
The angle connector helps to fix the RF source cable in an angle of 90°.
At the load end of the RS 9244 the rod ist terminated with a 50 Ohm RF load.
Angle connector, 50 Ohm RF load and attenuator are not included in delivery.
