Description
RANGE
ERROR:F1 > F2
ERROR:F1 > F2
The start (F1) frequency is greater than the stop (F2) frequency.
RANGE
ERROR:D1 > D2
ERROR:D1 > D2
The start (D1) distance is greater than the stop (D2) distance.
RANGE
ERROR:D2 >
DMax=xx.x ft (m)
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:
