SYSTem:PROPerties:CH<x>:CLKUser? (No Query Form)
This query returns the allowable range for a User (custom) clock rate for Ch<x>
as <nr3> - <nr3>. The channel speci
fi ed must be from an optical sampling module
that provides continuous clock-recovery capability in order to return a range; if
not, "NONE" is returned.
The allowable range is the range supported by the module providing the speci fi ed
channel; values within the range returned by this query can be used to specify the
User clock rate when using the TRIGger:CH<x>:CLKRec:USEr command.
