Softkeys displayed by pressing the [Search] key
Table B-68 Trace bandwidth analysis definition (Widths Def) menu
Key operation: [Search] - WIDTHS DEF MENU
Softkey Function GPIB command
MKRVAL¤(Ö2)
|
Uses the value obtained by dividing the measurement parameter value at the
main marker on the current active trace (A or B) by Ö2 as the value of the cutoff
point for trace bandwidth search.
WIDVTYPE DIVS2
MKRVAL*(Ö2)
|
Uses the value obtained by multiplying the measurement parameter value at the
main marker on the current active trace (A or B) by Ö2 as the value of the cutoff
point for trace bandwidth analysis.
WIDVTYPE MULS2
MKRVAL¤2
|
Uses the value obtained by dividing the measurement parameter value at the
main marker on the current active trace (A or B) by 2 as the value of the cutoff
point for trace bandwidth analysis.
WIDVTYPE DIV2
FIXED VALUE Directly enters the cutoff point for trace bandwidth analysis. WIDVTYPE FIX and
WIDFVAL <value>
SEARCH IN When the trace bandwidth analysis function is on, searches for two (left and
right) cutoff points on the trace inwardly, relative to the currently displayed
cutoff points, and displays the parameters of the trace bandwidth analysis for the
first detected cutoff points. Executing this key does not change the peak values.
If two new cutoff points are not detected, “TARGET VALUE NOT FOUND” is
displayed in the upper left area of the screen.
WIDSIN
SEARCH OUT When the trace bandwidth analysis function is on, searches for two (left and
right) cutoff points on the trace outwardly, relative to the currently displayed
cutoff points, and displays the parameters of the trace bandwidth analysis for the
first detected cutoff points. Executing this key does not change the peak values.
If two new cutoff points are not detected, “TARGET VALUE NOT FOUND” is
displayed in the upper left area of the screen.

Softkey Function GPIB command
PART SRCH on OFF For the current active trace (A or B), toggles on and off the partial search
function. The partial search function executes search within the specified range
on the trace. If the partial search function is on, both edges of the currently
specified search range are indicated by two small Ds. If no search range is
specified, the search range is the entire trace (same as when partial search is off).
PARS {ON|OFF}
MINIMUM For the current active trace (A or B), directly enters the lower limit of the partial
search range.
SEARMIN <value>
MAXIMUM For the current active trace (A or B), directly enters the upper limit of the partial
search range.
SEARMAX <value>
MKR ® MINIMUM Substitutes the sweep parameter value at the main marker on the current active
trace (A or B) into the partial search range lower limit. In other words, the sweep
range is changed by using the current position of the main marker as the new
partial search range lower limit.
