8.2.15. Test setup calibration with a CDNThe calibration setup always refers to the type of CDN. The CDN user manuals and the NSG 4070 Control Program show the required setup. (Immunity Menu / Global setup / Show test setup pictures). Examples for the system calibration of CDN M016 and CDNSareshowninthefollowingfigures:

8.2.22. Calibration of the monitoring probeTeseq recommends using the MD 4070 monitoring probe due to the operating range of the power meter. The active mode of MD 4070 allows also the operation with low stress levels. Details given in Table 11. The active mode requires to connect the power supply with the MD 4070. Using the whole dynamic range requires to calibrate the MD 4070 in the active and passive mode. The remote controlled switching requires connection with the NSG 4070 user port. The probecalibrationmeasurestheinsertionlossina50Ωsystem.
CAUTION: Usingpoweramplifierswithmorethan100Wattsrequirestoprotectpower meter channel 1 with an attenuator of at least 10 dB.
