Spectrum Averaging
The Averaging control on the bottom right side of the screen provides expo−
nential averaging of the frequency spectrum display. The number of aver−
ages is set with an up/down button, or with direct numeric entry.
For an averaging value of N, exponential averaging sums the latest N values
for each frequency display point (FFT point) and divides each value by N.
The larger the value of N, the more averaging occurs.
If the Peak Hold button is pressed, the right−hand window will display the
peak amplitudes across all the bandwidths.

Baseband / IF Frequency Scale
Signals translated by the DDCs from an IF frequency down to baseband can
be displayed with the frequency indicator showing either the original IF
frequency (default) or the down−converted Baseband frequency. The IF
toggle switch is changed by clicking on it. When you toggle the switch, the
label on the switch will change back and forth from IF to Baseband.

NOTE:
This feature is only available for DDC output signals.
