Analysis in Time Domain (Option 010)
Transformation to time domain
Operation
Step 1. Press (or ) and (or ) to activate a trace for
which you want to set the window.
Step 2. Press and then press
Transform
to display the “Transform” menu.
Step 3. Press
Window
and then select a window type.
Softkey Function
Maximum
Sets the window type to maximum.
β
of the Kaiser Bessel function is set to
13.
Normal
Sets the window type to normal.
β
of the Kaiser Bessel function is set to 6.
Minimum
Sets the window type to minimum.
β
of the Kaiser Bessel function is set to
0.
Rise Time
Sets the window by specifying the impulse width or the step rise time. The
lower limit can be set to the value when the window is the minimum, the
upper limit when the window is the maximum.
Kaiser Beta
Sets the window by specifying the
β
value of the Kaiser Bessel function.
The Kaiser Bessel function determines the shape of the window. The
allowable setting range is 0 to 13.
NOTE
By specifying
Kaiser Beta
, Impulse Width
, or
Rise Time
, you can specify a window that is
not classified into the three window types. Conversely, when you specify a window type,
these values are set automatically.
Calculating necessary measurement conditions
To use the transformation function efficiently, you need to make the following three
settings appropriately.
• Resolution of the response
• Measurement range
• Sidelobe
This section describes the details of these settings.
