Calibration of the measurement set-up

The EPM 02 and/or BPM 02 are used to calibrate the measurement set-up. During calibration, the
generated field strength is measured and adjusted via the power level of the signal generator to
achieve the desired test field. The power level that is required depends on the frequency and has
to be determined and stored for the respective frequency range during calibration. The stored
values can then be used to measure the test IC's immunity. The field meters are removed and the
test board with the IC is installed in the measurement set-up for this purpose.
As an alternative, the voltage can also be recorded at the measurement output of the field source
during calibration. The recorded voltage values can then be compared with the values obtained
from the ongoing immunity measurements. This comparison allows the user to check if the
measurement set-up works correctly.
The EPM 02 is used to check the P1501 or P1502 field source.
The BPM 02 is used to check the P1401 or P1402 field source.

The basic measurement set-up corresponds to
the ground adapter instead of the test IC. The field strength that is generated by the field source
can be determined on the basis of the relations described in section 2.4.
