, then enter a frequency value for the point.
NOTE
Only two entries per frequency are used. If more points with the same frequency are entered, only
the first and last entries are used. All other amplitude values are ignored. See Figure
3-13
for an
example of two entries at the same
frequenn/.
NOTE
When entering amplitude-correction data, the frequency and amplitude values will be listed as asterisks
(***I
until new values are entered. Once the frequency value is entered, the segment is immediately
sorted into the table according to this value.
Selecting the Amplitude
The amplitude value is entered by pressing SELECT
AMPLITUD
, entering an
Coordinate
amplitude value, and pressing a units key.
NOTE
Frequency or amplitude values that are not within range will be modified. For example, a frequency
value of 3
GHz
will be modified to 1.9
GHz.
