Data entry is simplified if you are entering new
correction pairs in frequency order. After using the
EDIT FREQ softkey and entering the frequency data, a
default amplitude is provided and the EDIT AMPL
softkey is activated.
This default corresponds to the previous amplitude
correction value in the list, if one exists, or 0 dB if the
new point is the first correction on the list. If you use
the numeric keypad and one of the terminator keys to
enter the amplitude value, the correction list
automatically moves to the end of the list and activates
the EDIT FREQ softkey, allowing you to enter a new
correction point.

EDIT
Allows you to modify the frequency information
FREQ
associated with the currently selected correction point.
After pressing this softkey, the numeric keypad can be
used to enter a frequency. This may be the frequency for
a new correction point or a new frequency for a point
that already exists. The knob and step-keys are
inactive during "edit frequency".
The list of frequency-amplitude correction pairs is
sorted according to frequency as soon as a frequency
entry has been terminated. The currently selected
correction point remains as the frequency which has
just been entered. A maximum of 200 correction points
can be entered.
You may have a frequency point that must be corrected
with different values when it is approached from a
lower frequency, than when it is approached from a
higher frequency. This discontinuous correction can be
created by entering the same frequency more than once
with different correction amplitudes. Corrections
specified for the same frequency remain on the list in
the order in which they were entered. The ampcor
function interpolates the correction. At measurement
frequencies below the duplicate frequency, it uses the
amplitude value corresponding to the first correction
pair entered. Corrections applied above the duplicate
frequency are interpolated using the last amplitude
entered at the duplicate frequency. Once entered, the
amplitudes at the duplicate frequency can be edited to
obtain the desired correction behavior.
