The measurement plots a theoretical BPSK bit error probability along the y-axis and the swept variable (typically Eb/N0) along the x-axis. The y-axis should normally be set to use log scaling.
The measurement generates a reference curve based on the settings of the meter block selected in the BER/SER Meter setting. Values for Pb are calculated for each value specified in the meter's SWPTV parameter.
The following BPSK modulation types are supported:
where Q(x) is the Gaussian integral or Q-function:
and is approximated numerically, Eb is the average bit energy and N0 is the noise power spectral density.
where the ideal narrow-band IF filter has bandwidth W=0.57/T, where T is the bit (and symbol) duration.
