Enables you to choose the available format of the selected trace.
The formats are:
Format Name Description
Log Mag (dB) Data is converted to decibel units and shown on a linear Y axis
Phase Phase of complex data is shown on Y axis
Group Delay Useful for frequency response displays. Shows the derivative of phase response with respect to frequency
Real (I) Real part of ccEVM per symbol
Imaginary (Q) Imaginary part of ccEVM per symbol
