NR3
100000000000
The current frequency span in NR3 format. Legal values are 1 Hz to 100 GHz. If you set the frequency span to a value outside of the legal range, the step size is automatically set to the nearest legal value.
The :FUNCtion[:FFT]:SPAN command sets the frequency span of the display (left graticule to right graticule) when FFT (Fast Fourier Transform) is selected.
