Frequency Offset Using Power Sensor (FOPS) – Option 208
FOPS Settings
— Num Points
sensor measurements between the Start and Stop frequencies. Enter one
setting and the other will be changed automatically. There must be at least
two data points.
— Dwell /Point
steps to the next frequency and before the power sensor makes a
measurement.

Amplitude Markers

Amplitude markers are horizontal dotted lines that you can move to any
amplitude level on the screen. The two amplitude markers can be set
independently or used as a pair of delta markers. Amplitude markers can be
used as a visual comparison aid with the data trace.
How to make Amplitude Marker settings

Memory features work as documented EXCEPT for the following:
When Trace, then Data -> Mem is pressed, if a Src Power trace is active,
then RxPower is actually stored into memory.
To Compare Src Power (Input) and Rx Power (Output):
1. Meas Rx Power
2. Store to memory

Delta Ampl Mkr.
— ON AmplMkr 2 value is relative to AmplMkr 1. When AmplMkr 1 is
moved, AmplMkr 2 also moves to maintain the AmplMkr 2 value
between them.
— OFF The two amplitude markers move independent of one another.
