This read-only object holds the real component of a complex-valued data sample captured in a snapshot, expressed as a fixed-point value requiring the snapshot's scale and precision objects to interpret. RF measurements like signal phase or I/Q data are often complex numbers, so this real-part value must be read alongside its imaginary counterpart for a complete sample. For example, an engineer analyzing constellation or phase data from a snapshot would pair each p2mpRealPart entry with the corresponding p2mpImaginaryPart entry to reconstruct the full complex sample.
