Command Descriptions
Arguments
<NR3> specifies
the point in the FFT waveform data record to display at the
center vertical graticule line. The data record point is a percentage of the total
record length, in the range of 0 to 100. The default value is 50. How much data
is displayed depends on the FFT Zoom factor setting. The oscilloscope rounds
<NR3> to the nearest workable value.
Examples
MATH:FFT:HORIZONTAL:POSIT ION 25 sets the FFT waveform horizontal
position such that the data at the 25% point of the record is centered on the display.
MATH:FFT:HORIZONTAL:POSIT ION? might return 5.0E1, indicating that the
50% point in the data record is horizontally centered on the display.
MATH:FFT:HORizontal:SCAle
NOTE. You can use this command with TDS1000, TDS2000, TDS1000B,
TDS2000B, TDS2000C, and TPS2000 oscilloscopes, as well as a TDS200
oscilloscope with a TDS2MM measurement module.
Sets or queries the FFT math waveform horizontal zoom factor.

Syntax
MATH:FFT:HORizontal:SCAle <NR3>
MATH:FFT:HORizontal:SCAle ?
Arguments
<NR3> specifies the h orizontal magnification factor, where the axis of
magnification is the center vertical graticule line. Valid zoom factors are 1, 2, 5,
and 10. If other values are entered the oscilloscope rounds the value of <NR3> to
the nearest valid zoom factor.
Examples
MATH:FFT:HORIZONTAL:SCALE 5 sets the FFT wa veform horizontal zoom
factor to X5.
MATH:FFT:HORIZONTAL:SCALE? might return 2.0E0, indicating that the zoom
factor setting is X2.
