WIDFVAL?
Description For the active trace (set with the “TRAC” command on page 457), if the free cutoff value
setting is enabled (specified to FIXed with the “WIDVTYPE” command on page 462), sets
a cutoff point. If
Δ
maker is on, the cutoff value is set the result of subtracting the specified
value from the measurement parameter value of
Δ
maker position.
Parameters
If the specified parameter is out of the allowable setting range, the minimum value (if the
lower limit of the range is not reached) or the maximum value (if the upper limit of the
range is exceeded) is set.

WIDSIN
Syntax
WIDSIN
Description
For the trace bandwidth analysis function for the active trace (set with the “TRAC”
command on page 457), further searches for another cutoff point inside the already
detected cutoff point. If no cutoff point is detected, the message indicating the result is
displayed (no error occurs). If the trace bandwidth analysis function is off, executing this
command causes an error and the command is ignored. (No query)

<numeric>
Description
Cutoff value
*1
Range -100E6 to 100E6
Initial value 0
Unit Varies depending on the measurement parameter (refer to the
explanation of unit in “SCAL” on page 423).
*1.If the measurement parameter is a vector value (for COMPLEX Z-Y)
and if the polar chart format is selected, set the value in amplitude. If
the complex plane format is selected, set the value in resistance (for
trace A) or conductance(for trace B).
