FFT 3030 EMI Receiver is ideal suited for measurement of
electromagnetic interference in accordance with the requirements of
CISPR 14-1 (household appliances industry) and CISPR 15 (lighting
equipment industry) standards.
Further to conducted emission
measurements from 9kHz to 30MHz with LISN, CISPR 14-1 standard
requires radiated power emission measurements from 30MHz to 300MHz
with absorbing clamp, CISPR-15 standard requires radiated emission
measurements from 30MHz to 300MHz with CDN method.

Why an attenuator and pulse limiter?
An Attenuator
and Pulse Limiter is used during EMI testing to provide input protection
to EMI receivers against high spikes coming from a LISN. |
The input attenuator, the preamplifier, the pre-selector or input mixer
can be destroyed in EUT testing due to a very high spectral
density/pulse energy. For high voltages as occur e.g. in LISNs or
absorbing clamp measurement, we strongly recommend to make use of the
external Pulse Limiter � Attenuator PAT 20M with every kind of EMI
Receiver.
This 20dB attenuator is designed for pulse voltages up
to 1Ws, to protect the input receivers. Even using EMI Test systems
already protected against spikes, for unknown devices under test, the
PAT 20M pulse limiter is strongly recommended. |
