SHC-1/1000, SHC-2/1000 –

Passive probes compliant CISPR 16-1-2,

9 kHz – 30 MHz


When LISN (Line Impedance Stabilization Network) are not applicable to EMI conducted test because the current flowing is too high, the conducted interferences are measured by means of a high impedance voltage probe, according to C.I.S.P.R 16-1-2.
The passive probes are designed to comply with C.I.S.P.R. 16-1-2 regulation and thus include a blocking capacitor to decouple the measured signal from any AC supply voltage which may be present on the line under test, they have a total internal resistance between line and earth of more than 1500 ohm.
Uncompromised design and construction for reliable and safe operation together with every PMM-Narda EMI receiver like the 9010F or any other suited RF receiver.
