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.

Trace Math
Trace Math allows you to compare data traces and perform simple math. Learn how
to use Trace Math beginning on page 122. All Data and Memory features work as
documented EXCEPT for the following:
NOTE 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):
90

Num Points Freq Step Size
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.
Specifies a settling time (in seconds) after the internal source steps
Dwell /Point
to the next frequency and before the power sensor makes a measurement.
