CALCulate<Chn>:LIMit:FAIL?
Returns a 0 or 1 to indicate whether or not the limit check has failed. 0 represents pass
and 1 represents fail
Tip:
to perform a composite (global) limit check.
Since V2.20 of the R&S
ZNL/ZNLE FW the result is automatically recalculated when-
ever a relevant setting is changed, i.e. a subsequent query will return the updated limit
violation state.
Suffix:
<Chn>
.
Channel number used to identify the active trace
Example:
*RST; :CALC:LIM:CONT 1 GHZ, 2 GHZ
Define an upper limit line segment in the stimulus range
between 1 GHz and 2 GHz, using default response values.
CALC:LIM:STAT ON; FAIL?
Switch the limit check on and query the result.
CALC:LIM:STAT:AREA LEFT, TOP
For a subsequent check at the GUI or a hardcopy, move the
pass/fail message to the top left position.
Usage:
Query only
Manual operation:
See
CALCulate<Chn>:LIMit:LOWer[:DATA]
<ResponseValue>, <ResponseValue>...
CALCulate<Chn>:LIMit:UPPer[:DATA]
<StartResponse>,
<StopResponse>[,<StartResponse>, <StopResponse>[,...]]
Sets/gets the response (y-axis) values of the lower/upper limit lines and/or creates new
limit line segments. See also
Chapter 8.4.1.1, "Rules for Limit Line Definition"
Note
that in contrast to commands addressing a single limit line segment
<Seg>
(such
CALCulate<Chn>:LIMit:SEGMent<Seg>:TYPE
), these commands
assume
that
●
lower limit line segments are assigned even numbers (
<Seg> = 2,4,6,...
) and
●
upper limit line segments are assigned odd numbers (
<Seg> = 1,3,5,...
).
CALCulate<Chn>:LIMit:LOWer/UPPer
sets the type and response values of
even/odd limit line segments and gets the response values of even/odd limit line seg-
ments - no matter what the current type of these segments actually is!
Both commands will only work, if the total number of limit line segments is even.
Rules for creating and updating segments
Suppose that the active trace is equipped with 2s limit line segments (of any type) and
k pairs of response values are passed with the command.
●

–
deletes "obsolete" limit line segments 2k+1, ..., 2s
