10.4 Preemphasis
Each GAB/2 provides three preemphasis terms (exponential functions), each with selectable
gain and time constant. Typing setpre in TopSpin (command line) opens a window for
definition of the preemphasis parameters.
Note: The time constants by setpre are defined in milliseconds, whereas the BSMS Service
Web provides time constant setting in seconds.
