Model CDN -AF4
4.0 Establishing a drive table
Before you begin you will need to test your setup to establish
the correct immunity levels. The setup is similar to the
attenuation measurment setup except connect the power
amplifier to the CDN input (please see figure 2-5). The 1EC-
1000-4-6 call out testing to three different open circuit test levels.
The table below shows unmodulated disturbing signal levels
expressed in r.m.s.
