QPSK EVM Measurement
Meas Setup

Meas Interval

Specifies how long the signal is observed.

Spectrum

Toggles the spectrum function between Normal and Invert. If set to Invert, this function conjugates the

spectrum. It is equivalent to taking the negative of the quadrature component in demodulation.
