Setting Measurement Conditions
Combining Two or More Sweep Conditions (List Sweep)
Combining Two or More Sweep Conditions (List Sweep)
You can carry out a sweep (list sweep) by combining the segments that set the sweep
condition; these segments can provide up to 18 identical sweep parameters. To carry out a
list sweep, prepare a table of segments. At the start and the end of the table, send the
commands given below.
• “EDITLIST” on page 310
• “EDITDONE” on page 310
NOTE
If the “EDITDONE” command is not executed, the resulting settings from making, editing,
and deleting with the commands given below will not take effect. (The table to be used in
carrying out a list sweep is left as it was before the execution of the “EDITLIST”
command.)
Making/editing a segment
To make a new segment, use the commands given below. The “SADD” command adds a
segment so that you can edit it. To make settings for a segment’s parameters, use the
commands for setting identical parameters described in “Setting Measurement Signals” on
page 38, “Setting a Sweep Condition” on page 39 and “Setting Averaging” on page 43.
After setting the parameters, send the “SDON” command to finish setting the segment.
• “SADD” on page 415
• “SDON” on page 426
Each segment is assigned a segment number (a row number in the table) for specifying the
segment to be set, changed or deleted. To specify the number of the segment to be worked
on, use the command given below.
• “SEGM” on page 435
Executing the “SADD” command makes an additional insertion under the line of the
specified segment (if no segment is specified, then the segment to be worked on at the time
of executing the command involved), and the added segment becomes the target of setting.
Thus you don't need to specify segment numbers for the “SADD” command while making
a new table by adding segments in the intended sequence. You need to specify a segment
number only when adding a new segment at a position between two existing segments.
To change the parameter settings of existing segments, use the command given below to
make a specified segment changeable (if no segment is specified, then the segment to be
worked on at the time of executing the command involved). After changing the parameters,
send the “SDON” command to finish changing segments.
