Is the Current Grid Harmonic?
The area at the top of the "Low Pass Settings" dialog indicates whether the current fre-
quency grid is harmonic.
Remote command:
Set Harmonic Grid and Keep
The three buttons provide alternative algorithms for calculation of a harmonic grid,
based on the current sweep points.
●
Keep "Stop Frequency and Number of Points" calculates a harmonic grid based on
the current "Stop Frequency" (see
"Start Frequency / Stop Frequency / Center Fre-
on page 474) and the current number of sweep points
(see
on page 489). This algorithm can increase the frequency
) .
●
Keep "Frequency Gap and Number of Points" calculates a harmonic grid based on
the current "Stop Frequency" and the current frequency gap (i.e. the "Freq Step
Size").
●
Keep "Stop Frequency and Approximate Frequency Gap" calculates a harmonic
grid based on the current "Stop Frequency", increasing the "Number of Points" in
such a way that the frequency gap (i.e. the "Freq Step Size") remains approxi-
mately the same. This algorithm can increase the sweep time, due to the additional
sweep points introduced.
The three grids can be calculated repeatedly in any order; the analyzer always starts
from the original set of sweep points.
