CDN 118A Series
CDN 118A-C4-4-1
CDN 118A-C6-4-1
Coupling network for surge and
telecom-surge to signal and datalines
The coupling network of the CDN 118A series are designed for
coupling surge and telecom-surge pulses to symmetrical signal
or datalines.
The coupling network expands the range of application of the
impulse generator of the NSG 3040A and NSG 3060A series,
for testing signal and datalines.
Main characteristics are the advantages for handling and the
easy using with banana plugs.
