4. Select "Define Reference".
Figure 8-8: Defining the reference curve, e.g. in frequency mode
In this dialog, you can specifiy a linear reference curve for the measurement of the
corresponding trace. The measurement mode, selected with Configure measure-
ment settings, determines the parameters assigned to the x-axis and the y-axis in
the diagram.
The remote commands required to define these settings are described in Chap-
ter 14.15, "SENSe, READ, INITiate and SLISt subsystems", on page 546.
Freq (X)
For Configure measurement settings > "Frequency", sets the frequency values for
points A and B of the reference curve.
Remote command:
:SENSe[:POWer]:SWEep:FREQuency:REFerence:DATA:XVALues on page 513
:CALCulate[:POWer]:SWEep:FREQuency:MATH<ch>:XVAL on page 495
POW (Y)
For Configure measurement settings > "Frequency", sets the power values for points A
and B of the reference curve.
Remote command:
:SENSe[:POWer]:SWEep:FREQuency:REFerence:DATA:YVALues on page 513
:CALCulate[:POWer]:SWEep:FREQuency:MATH<ch>:YVAL on page 495
Pow (X)
For Configure measurement settings > "Power", sets the power values for points A and
B of the reference curve on the x-axis.
Remote command:
:SENSe[:POWer]:SWEep:POWer:REFerence:DATA:XVALues on page 525
:CALCulate[:POWer]:SWEep:POWer:MATH<ch>:XVAL on page 497
