1.2 Introduction to
PL01 Pulse Limiter
Enclosed with this manual are a service questionnaire to send back to
NARDA in case that equipment service is needed.
The Pulse Limiter PL01 is an accessory designed to protect the input circuit
of a Receiver against high energy interfering voltage pulses.
The Pulse Limiter does not cause any significant change of the measured
signal and loss in sensitivity on the measuring receiver.
Its main function is to suppress the transients that can occur when the test
item, connected to an artificial mains network LISN, is switched on or off.
When operating the receiver from artificial mains network LISN, the Pulse
Limiter PL01 must be used particularly when very strong interfering signal is
suspected. The precision input attenuator and the input mixer of the
receiver are therefore protected from being damaged.
On the other hand if the disturbance signal and spikes do not exceed the
maximum input voltage permissible for the receiver, the use of the Pulse
Limiter can be omitted.
Designed according to criteria of cheaply and compactness it can be used
together with PMM 9010F for conducted interferences measurement, or
any other RF receiver.
