This allows amplitude correction to be entered to
compensate for changes in conversion loss with
frequency. To enter a new value, use the data keys. To
change the displayed frequency, use the step keys. Any
changes to the data also affect the mean conversion loss
stored under AVERAGE CNV LOSS. <Undefined
Cross-Reference> shows the number of flatness points
for each band and the default flatness values. To view
the correction, connect a 310.7 MHz signal of a known
amplitude (approximately −30 dBm)to the IF inputand
set the analyzer to sweep the associated band.
