CALCulate:LIMit:FAIL:DATA? <TraceName>, <LimitFailType>
Returns those sweep points that have caused a limit violation of the given <LimitFail-
Type> for trace <TraceName>.
Query parameters:
<TraceName> Trace name, uniquely identifying the related trace
<LimitFailType> LIMit | RIPPle | CIRCle
Limit (fail) type
Usage: Query only
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 9.4.1.1, "Rules for limit line definition",
on page 230.
Note that in contrast to commands addressing a single limit line segment <Seg> (such
as 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.
●
CALCulate:LIMit:LOWer
– deletes "obsolete" limit line segments 2k+1, ..., 2s
– updates even limit line segments 2, 4, ..., 2s with type=lower and the given
response values
– creates lower limit line segments 2s+2, 2s+4, ..., 2k with (type=lower and) the
given response values
– creates "missing" upper limit line segments 2s+1, 2s+3, ..., 2k-1 with
(type=upper and) default response values
●
CALCulate:LIMit:UPPer
– deletes "obsolete" limit line segments 2k+1, ..., 2s
– updates odd limit line segments 1, 3, ..., 2s-1 with type=upper and the given
response values
