A W appears on the left edge of the display to indicate
the function is active. If you have not previously edited
or recalled correction data, then the ampcor function is
not activated and the message No Correction Loaded
appears in the active annunciator area of the display.
Each correction point consists of a frequency at which
the correction should be applied and an amplitude, in
dB, of the correction. For frequencies between
correction points, the ampcor function linearly
interpolates the correction data you have entered.
Frequencies outside the range over which you have
specified correction are corrected by the amplitude
values at the nearest (in frequency) end of the list of
correction data. The correction is automatically
recalculated for any span or vertical scale, including
linear.
If any of the trace data is above or below the graticule,
the ampcor function may not properly correct it. The
spectrum analyzer amplitude accuracy is not specified
above or below the graticule. Anytime ampcor applies a
correction such that data outside the graticule is moved
to within the graticule, an error (error number 921 or
922) is generated. In order to avoid these errors, make
sure that the trace data which is being corrected is
within the graticule before the correction is applied.
