Error Message Description
RANGE
ERROR:F1 > F2
The start (F1) frequency is greater than the stop (F2) frequency.
RANGE
ERROR:D1 > D2
The start (D1) distance is greater than the stop (D2) distance.
RANGE
ERROR:D2 >
DMax=xx.x ft (m)
The stop distance (D2) exceeds the maximum unaliased range. This
range is determined by the frequency span, number of points,
and relative propagation velocity:
MaximumUnaliased Range
dp V

21
Where: dp is the number of data points (130, 259, or 517)
V
f
is the relative propagation velocity
F2 is the stop frequency in Hz
F1 is the start frequency in Hz
Maximum Unaliased Range is in meters
RANGE ERROR:
TOP<=BOTTOM
The SWR scale parameter top value is less than or equal to its bottom
value.
RANGE ERROR:
TOP>=BOTTOM
The RL scale parameter top value is greater than or equal to its bottom
value.
