The following instruction defines Trace f1 to compute the Power
Spectrum of the FFT of Channel 1. The window function is
Rectangular.
CMD$=“F1:DEF EQN,‘PS(FFT(C1))’,WINDOW, RECT”:
CALL IBWRT(SCOPE%,CMD$)
The following instruction defines Trace F2 to compute the Power
Average of the Power Spectrum of Channel 1, over a maximum of 244
sweeps.
CMD$=“F2:DEF EQN,
'AVG(FFT(C1))',TYPE,POWERSPECTRUM,WINDOW,RECTA

The following instruction defines Trace F3 to construct the histogram
of the rise time measurements made on source Channel 1. The rise time
measurement is defined on custom line 2. The histogram has a linear
vertical scaling, accumulates up to 1000 parameter values, and rescales
automatically. The rise time parameter values are binned into 100 bins.
