The RUNTil (run until) command allows you to define a stop condition when the trace mode is repetitive. Specifying OFF causes the analyzer to make runs until either the display’s STOP field is touched or the STOP command is issued.

There are four conditions based on the time between the X and O markers. Using this difference in the condition is effective only when time tags have been turned on (see the TAG command in the STRigger subsystem). These four conditions are as follows:

∙The difference is less than (LT) some value.

∙The difference is greater than (GT) some value.

∙The difference is inside some range (INRange).

∙The difference is outside some range (OUTRange).

End points for the INRange and OUTRange should be at least 8 ns apart since this is the minimum time resolution of the time tag counter.

There are two conditions which are based on a comparison of the acquired state data and the reference listing. You can run until one of the following conditions is true:

∙Every channel of every label has the same value (EQUal).

∙Any channel of any label has a different value (NEQual).

<value> real number from −9E9 to +9E9
