2- and 4-line-filters
Standard filters for measuring cabins
Single-stage
Stopband attenuation 150 kHz to 40 GHz
Features
General-purpose use through design with separate lines without intercoupling
Use of single chokes. Thus the insertion loss values are not reduced under all operating cur-
rent conditions and not when operated with artificial mains networks (AMN) or other equipment
with high leakage currents.
Insertion loss to CISPR 17
Design
The electrical components are incorporated in an RF-tight case of stainless steel. The cables
enter through glands. The RF-tight termination of the openings is produced by specially shaped
lids.
The conductors and equipment grounding conductor are connected by threaded bolts. The sur-
face around the fixing holes is left as bare metal (unpainted) to ensure good RF contact with met-
al surfaces (chassis, ground).
Protective measures (grounding)
The high capacitances between the lines and ground require special protective measures. If there
are no product-specific requirements, protection with a secondary ground wire (cross section min.
10 mm
2
) in accordance with EN 50178 is necessary. For this purpose the filter case have con-
necting bolts at each end.
Resistors are incorporated in the filter to discharge capacitors after turn-off.
Scope of supply
Filters are supplied complete with all parts required for RF-tight installation (fixing screws,
flanges, RF gaskets, cable glands) and installation instructions.
Installation
No welding is needed on the shielding wall, so any subsequent installation is quite simple.
Accessories and special versions
RF-tight flexible connector fittings are available for installation spaced away from the shielding
wall. Filters with an EMP protection add-on for surge currents up to 100 kA per line are available
on request. To match requirements, filters can be supplied with different kinds of EMC or shield-
ing cable glands.
Tests
All filters are 100% tested and the results are archived under a filter's serial number. If required, a
test report can be generated for the serial number.
