FieldMan Narda
8.1 Overview of operating modes and
probe types
Depending on the connected and recognized probe type, the following operating modes
are available for selection in the FieldMan:
FIELD STRENGTH (FS)
Measurement of field strength or flux density and numerical representation of the mea-
surement results for a defined frequency range, which may be broadband or band-lim-
ited. A time curve (
Time Curve
) can be optionally activated for the measurement results,
which is implemented as a rolling memory.
⇒
See 8.2 FIELD STRENGTH on page 60 .
SPATIAL AVERAGE (SA)
Allows spatial averaging of measured field strength values from multiple measurement
positions and is mostly required for measuring thermal effects with HF probes. Averaging
is done via the square of the field strength values (RMS averaging). In addition, a delay
can be set for the measurement start. This allows the person performing the measure-
ment to move away from the measuring location to avoid influencing the field.
