Saving Data
Overview
Antenna factor units are dBuV/m, dBuA/m, dBpT, and dBG. In this case, the unit is
treated exactly as though it were dBuV, meaning that all of the limits are interpreted
to have units of dBuV. The box does NOT change Y Axis Units when such a limit is
loaded in.
The X axis unit also specifies the domain (time or frequency). It is not possible to
have both time-domain lines and frequency-domain lines at the same time; if a
time-domain line is imported while the other lines are in the frequency domain (or
vice-versa), all limit lines will be deleted prior to import.
If the sign of the margin is inappropriate for the limit type (for example a positive
margin for an upper limit), the sign of the margin will be changed internally so that it
is appropriate.
The remaining lines describe the data. Each line in the file represents an X-Y pair.
The X values should be monotonically non-decreasing, although adjacent lines in the
file can have the same X value as an aid to building a stair-stepped limit line. To
specify a region over which there is no limit, use +1000 dBm for upper limits or
-1000 dBm for lower limits.
.lim file format
This is a legacy format which allows files saved from older analyzers to be loaded
into the X-Series. Design of files in this format is not recommended.
