9 to the list table.

LOGSWEEPREQUIRES2 OCTAVEMINIMUMSPAN

Error Number A logarithmic sweep is only valid if the stop frequency is greater than four

150times the start frequency. For frequency spans of less than two octaves, the sweep type automatically reverts to linear sweep.

LOWPASS: FREQLIMITSCHANGED

Information The frequency domain data points must be harmonically related from dc to the

Message stop frequency. That is, stop = n x start, where n = number of points If this condition is not true when a low pass mode (step or impulse) is selected and transform is turned on, the analyzer resets the start and stop frequencies. The stop frequency is set close to the entered stop frequency, and the start frequency is set equal to stop/n.
