• ON/OFF
Cursors can be placed on the displayed power spectrum waveform to measure and
display the value at any point. It can be used to measure the data on the vertical
axis (Y-axis) and horizontal axis (X-axis) of various sections of the power spectrum
waveform.
• ON: Performs cursor measurement.
• OFF: Does not perform cursor measurement.
• Measured Source
The source FFT of the cursor measurement can be set to FFT1 or FFT2.
• Moving the Cursors
• Cursors move on the selected power spectrum waveform.
• The cursors moves along the data points displayed on the screen one point at a
time.
• The cursor movement varies depending on the display range (section 11.6) of the
X-axis (frequency) as follows:
• Less than or equal to 1002 points
Specify the number of points from the left end of the screen to move the cursor
with the left and right ends of the screen assumed to be point 0 and the point
corresponding to the number of points of the display range, respectively.
• Greater than 1002 points ("1002(P-P)" is displayed at the center of the top
section of the screen)
Specify the number of points from the left end of the screen to move the cursor
with the left and right ends of the screen assumed to be point 0 and 1001,
respectively.
• Measurement Item
• Y+: Vertical value of cursor + (Y-axis value)
• Yx:
Vertical value of cursor x (Y-axis value)
• ∆Y: The difference between the Y-axis values of cursor + and cursor x
• X+: Horizontal value of cursor + (X-axis value, frequency)
• Xx:
Horizontal value of cursor x (X-axis value, frequency)
• ∆X: The difference between the X-axis values of cursor + and cursor x
Note
•
If immeasurable data exists, *** is displayed in the measured value display area.
• ∆Y is measured even if the unit is different. The result has no unit in this case.
