–The last command (:CALCulate:LIMit:FAIL:CUMulative?) is similar
to the one above, with the main difference that this query will tell whether
all measurements of the RMS-valued phase error taken since the last reset
of the cumulative check are within the limits set (then a
0 will be returned)
or whether at least one measurement result value did violate at least one of
the user-definable limits (in this case, the query will deliver back a
1).
CALCulate:LIMit The
CALCulate commands that incorporate the LIMit command element
– check whether one or more measurement result(s) did violate the user-
definable limits
– reset the cumulative limit evaluation system
– switch the limit evaluation system for specific measurements on or off
– set the limits
FAIL[:LAST]? - did the latest measurement result value fail?
{measProp}:LIMit[:FAIL] - did the latest measurement result value of
a specific measurement fail?
Syntax
:CALCulate:LIMit:FAIL[:LAST]?
Returns
0 when the limits were not violated or
1 in case at least one limit was violated by the latest measurement result value.
Description
Checks whether the latest measurement result value of the measurement started last
is within its limits.
Examples
:MEAS:GSM:ARR:RFTX:LENG
:MEAS:GSM:ARR:RFTX:PRMS
:CALC:GSM:LIM:FAIL:LAST?
This command of the CALCulate subsystem will check whether the latest measure-
ment result value of the PRMS measurement is within its limits.
:MEAS:GSM:ARR:RFTX:LENG 10
:CALC:GSM:LIM:FAIL:LAST?
In this example, the :CALC command will check if all 10 measurement result values
of the burst length measurement array are within their limits.
Syntax
:CALCulate:{measProp}:LIMit[:FAIL]?
Returns
0 when the limits were not violated or
1 in case at least one limit was violated by the latest measurement result value.
Description
Checks whether measurement result values of the measurement specified with the
{measProp} command element are within their limits.
In case, this command is used during a continuous measurement, only the latest
measurement result will be checked.
When this command is used subsequent to an array measurement, all measurement
result values of the array will be checked against the limits. This means that a 1 will
be returned if a single measurement result of an array is off the limits.
