sities of the specific channel ("Histogram"). It is self-scaling
and can be interpreted as follows:
 On the left side of the x-axis a formula calculates and
plots how often the minimum value has occurred in a
given time interval, and similarly on the right side for the
maximum value.
 The largest bar marks the value most frequently meas-
ured. Very low bars indicate a specific value very seldom
measured.

This chapter explains NFAsoft specific functions. Standard
software functions are omitted.
Edit
"Copy all"
Copies the plotted data area as well as the drop-down of the
"Statistics/Channels" section into the buffer – from here it
can be inserted directly into your measurement protocol at
any point of your choice. This is similar to a screen shot.
All other edit options are self explanatory.
View
"Edge Display"
Select the menu option View/Edge Display to activate the
edge display. The edge display option will help find im-
portant field strength fluctuations. Steep edges are marked
in the diagram in the colour corresponding to each channel –
the marked channel will be bolded, the others won't. This
way you will always have an overview of what's going on in
the other channels, even if your focal point is, for instance,
the 3D-value. The threshold value for an edge display can be
defined in the menu option "Channel/Set edge criteria".
"Set Times"
Choose the "Set Times" option to scale the graphic to a de-
fined time segment.
"Y-Scale"
 Automatic – The y-axis will be scaled automatically to
give the best display of the area selected for analysis.
 Manual – The y-axis scaling can be manually controlled
in this mode. Allows for and will assist in analyzing small
values (e.g. those over 2 kHz) overshadowed by other
very strong field intensities.
"All"
