10.2 Selection of a standard
There is a wide range of national and international standards setting exposure limits for
electric and magnetic fields. They can differ in frequency range and range of effect (influ-
ence on the body).
The standards (limit value curves) to be available for selection on the FieldMan can be
configured via the Narda-TSX PC software. Predefined standards are available, which
can be extended by self-c
reated standards.
User-defined standards are saved on the SD card during configuration and are marked
on the device with a preceding asterisk. Predefined standards, on the other hand, are
stored in the FieldMan.
The standards for evaluative measurements of the SHAPED TIME DOMAIN operating
mode are implemented in the measuring probes and can only be changed by a firmware
update of the manufacturer.
Reference Frequency Correction Factor Lowest Limit
The reference frequency
(Reference Frequency) is
displayed in the probe info
field, e.g. with REF: 2.45
GHz.
If the correction factor is ap-
plied at the same time, the
entry CF: 2.45 GHz ap-
pears instead.
When referring to the small-
est (strictest) limit value,
REF: Lowest Limit is dis-
played.
The standard selected in the menu is also shown in the display (in the yellow field above
the isotropic measured value).
