:TRIGger:ZONE<n>:VALidity
(see page 1610)
Query Syntax
:TRIGger:ZONE<n>:VALidity?
<n> ::= 1-2 in NR1 format
The :TRIGger:ZONE<n>:VALidity? query returns the validity of Zone 1 or Zone 2.
• INValid is returned (for Zone 2 only) when Zone 1 and Zone 2 overlap and have
opposing qualifying conditions (modes). Zone 1 can never be invalid.
• OSCReen (off-screen) is returned when the associated zone is off-screen, and
thus not being used to qualify the trigger.
• A zone is valid when it is neither invalid nor off-screen.
The validity of a zone is not affected by the zone's state. For example, a zone can
be valid and off. You cannot directly set the validity of a zone.
Return Format
<validity><NL>
<validity> ::= {VALid | INValid | OSCReen}
