Graph Results (Trace)
The
panel shows information about the Graph calculation for the active trace.Compensation must be enabled for to be calculated.
The following metrics are available:
- DEVM - differential error vector magnitude, averaged over all time points
- Gain - average gain of response data over stimulus data
- Delay - time difference between the stimulus and response data, calculated during time alignment compensation
- Stimulus Power - average power of stimulus signal
- Response Power - average power of response signal
- Coef N - coefficients for the curve-fit line
These graph results are not updated for each measurement sweep but are static until you click the
button or change the active trace.There are several buttons to the right of the Graph Results:
-
- recalculates the graph results based on the current contents of the active trace, which comes from the latest measurement sweep.
-
- copies the contents of the table to the clipboard as text. The text is in tabular format so you can paste into Excel, and the data will be formatted into columns automatically.
- - copies the curve fit line into a register that you specify. This is useful if you want to place a marker on the curve fit line or if you want to export the curve fit data to use in another application (through
