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 maxi-
mum unaliased range. This range is deter-
mined by the frequency span, number of
points, and relative propagation velocity:

Where: F1 is start frequency
F2 is stop frequency
Vf is relative propagation velocity
maximum unaliased range is in meters
Refer to Figure 2-10, page 2-38, for a plot of maximum
range versus frequency span.
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.
CAL
INCOMPLETE A complete open, short, and load calibration
must be performed before calibration can be
turned on.
CAL VALID FROM:
xxxx.x to
xxxx.x MHz
The calibration was performed at a fre-
quency range that is different from the cur-
rent range.
