Analysis and Processing of Result
Set a limit to the trace and make pass/fail evaluation
• In the even of a failure, the limit line test fail bit of the GP-IB status byte is set to “1.”
For more information on the GP-IB status byte, refer to

Figure 8-28 Limit line table editing with limit line test function
Move the limit line in vertical and horizontal directions on the screen
You can set the offset of the sweep parameter value and that of the measurement parameter
value for the entire limit line set in the limit line table.
When the horizontal axis represents a sweep parameter axis and the vertical axis represents
a measurement parameter axis, these offsets allow the entire limit line to move in the
vertical and horizontal directions. For example, this function allows the limit line to be set
according to the characteristics of a particular sample to be used for other samples with
different characteristics or with different measurement parameter values.
Step 1. Press the
[System]
key to display the System menu.
Step 2. Press the
LIMIT TEST
key to display the Limit Test menu.
Step 3. Press the
LIMIT LINE OFFSET
key to display the Limit Line Offset menu.
Step 4. Press the
SWP PARAM OFFSET
key to display the current sweep parameter offset value
for the limit line in the set parameter value field in the upper left area of the screen.
Step 5. Use the keys or rotary knob of the ENTRY block in one of the following ways to specify
the sweep parameter offset value.
• Enter the desired value with the numeric keys (
[0]
to
[9]
,

) and then press one
of the unit keys (

).
• Turn the rotary knob ( m
