• Vertical Axis Auto Scale (Y Axis Auto Scale)
The vertical scale is set so that the maximum and minimum values of the waveform
data in the vertical direction fit on the waveform display frame.
• Center Frequency of the Horizontal Axis (Center Frequency)
You can set the frequency displayed at the horizontal center point in the waveform
display frame.
Selectable range: 0.0 to (the clock frequency/2)
The resolution is (the clock frequency/the number of computed points). For a
description of the clock frequency, see section 5.3. For a description of the number
of computed points, see “Number of Computed Points” on the previous page.
Default value: 0.0
Unit: kHz or MHz
• Horizontal Display Range (Frequency Span)
You can set the range of frequencies displayed between the left and right edges of
the waveform display frame with the center frequency at the center of the waveform
display frame.
Selectable range: 0.0 to (the clock frequency)
The resolution is 2
×
(the clock frequency/the number of computed points). For a
description of the clock frequency, see section 5.3. For a description of the number
of computed points, see “Number of Computed Points” on the previous page.
Default value: 1000.0 kHz
Unit: kHz or MHz
• Horizontal Axis Auto Scale (Frequency Auto Scale)
The horizontal scale is set so that the result of the spectrum computation fits on the
waveform display frame.
