NSG 3040 EMC test system
NOTE - A Teseq CAS 3025 calibration set must be used
with a minimum 400 MHz digital oscilloscope to accu-
rately verify the EFT pulse parameters.
8.3.1 Test configuration with power line coupling
In a power line coupling test, the NSG 3040 generates the interference signal,
which is superimposed on the EUT power signal.
8.3.2 Test configuration with external coupling
In an externally coupled test, the interference signal is delivered through the
NSG 3040’s coaxial burst output connector (SHV-type) on the front panel and
fed to an external coupling clamp. The signal is then applied to signal or data
line cables.
The same SHV type connector may also be used for connection of a 3-phase
CDN or for a CDN suitable for 1-phase >16 A and all other CDNs.
