Avg Mode
Exp Repeat
Allows you to select the type of termination control used for the
averaging function. This determines the averaging action after the
specified number of measurements (average count) is reached.
Avg Mode has no effect on measurements that are not averaged.
Exp Each successive data acquisition after the average
count is reached is exponentially weighted and
combined with the existing average. Exponential
averaging weights new data more than old data, which
facilitates tracking of slow-changing signals.
Repeat After reaching the average count, all previous result
data is cleared and the average count is set back to 1.

2nd Car Offs
Allows you to change the frequency difference from the main carrier to
the second carrier, measured in MHz. The center frequency of the main
carrier is the analyzer center frequency less half of the second carrier
offset in MHz. The second carrier center frequency is the main carrier
center frequency plus the second carrier offset value in MHz. The
available offset values are –15, –10, –5, 5, 10, and 15 MHz. The
negative values set the offset below the main carrier frequency, and the
positive values set the offset above the main carrier frequency.
