The measurement plots a theoretical BPSK bit error probability
along the y-axis and the swept variable (typically
E_{b}/N_{0}) 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 P_{b} 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, E_{b} is
the average bit energy and N_{0} 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.
