Agilent Infiniium 90000 Series Oscilloscopes Programmer's Reference 411
:LTESt:ULIMit
(Upper Limit)
Command
:LTESt:ULIMit <upper_value>
The :LTESt:ULIMit (Upper LIMit) command sets the upper test limit for
the active measurement currently selected by the last :LTESt:MEASurement
command.
<upper_value> A real number.
Example
The following example sets the upper limit of the currently selected
measurement to 500 milli.
myScope.WriteString ":LTEST:ULIMIT 500E-3"
Suppose you are measuring the maximum voltage of a signal with Vmax,
and that voltage should not exceed 500 mV. You can use the above
program and set the LTESt:FAIL OUTside command to specify that the
limit subsystem will fail a measurement when the voltage exceeds 500 mV.
Query
:LTESt:ULIMit?
The query returns the current upper limit of the limit test.
Returned Format
[:LTESt:ULIMit] <upper_value><NL>
Example
The following example returns the current upper limit of the limit test and
prints the result to the controller's screen.
Dim strULIM As String
myScope.WriteString ":LTEST:ULIMIT?"
strULIM = myScope.ReadString
Debug.Print strULIM
