3.2 Swept SA Measurement
Limit Test Current Results (Remote Command Only)
Queries the status of the current measurement limit testing. It returns a 0 if the
measured results pass when compared with the current limits. It returns a 1 if the
measured results fail any limit tests.
Remote Command
:CALCulate:CLIMits:FAIL?
Example Query the current measurement to see if it fails the defined limits:
:CALC:CLIM:FAIL?
Returns a 0 or 1: 0 it passes, 1 it fails
Limit Line Fail? (Remote Query Only)
Tests a limit line against its associated trace. Returns a 0 if the trace is within the
limit and margin, a 1 if the trace exceeds either the limit or the margin.
Note that this command only tests one limit line – other limit lines are not tested
when executing this command. To see whether a trace passed all limits, use
:CALCulate:TRACe:FAIL?.
Note this command performs the test regardless of whether the trace or the limit is
turned on the display.
Remote
Command
:CALCulate:LLINe[1]|2|…|6:FAIL?
Example
:CALC:LLIN:FAIL?
returns a zero if limit line 1’s associated trace has no failure, 1 if there is a margin or limit failure
Limit Line Control (Remote Commands Only)
Defines a list of limit line control (frequency or time) values for a given limit line. Up
to 2000 points may be defined for each limit using the following parameters.
<x>
Frequency or time values as specified by :CALCulate:LLINe:CONTrol:DOMain.
Units default to Hz (for frequency) and seconds (for time)
Range: –30 Gs to +30 Gs for time limits, –3 kHz to +1200 GHz for frequency limits
Note that X values may be repeated if a vertical step in the limit line is desired.
The points query returns the number of points in the control. It should match the
number of points in the amplitude, that is, the number of values for the CONTrol axis
and for the corresponding UPPer and/or LOWer limit lines must be identical. If one
array is larger than the other, the limit trace is built using only as much data as is
contained in the smaller array.
