N-Series
Coupling network for
surge to signal and datalines
CNV 504N1.1, N1.2 , N1.3 , N1.6
CNV 508N1,
CNV 508N2,
The coupling network of the series CNV 504 / 508 are designed
for coupling surge- or telecom pulses to signal or data lines.
The coupling network expands the range of application of the
impulse generator UCS500, VCS500 and CSS500 for testing
signal and data lines.
Main characteristics are the advantages for handling and the
easy using with banana plugs.
