Examples
MEASUREMENT:IMMED:UNITS? might return
:MEASUREMENT:IMMED:UNIts "s"
indicating that uni
ts for the immediate measurement are in seconds.
MEASUrement:IMMed:VALue? (Query Only)
Returns the value of the measurement specified by the MEASUrement:IMMed:
TYPe command. The measurement is immediately taken on the source(s)
specified by a MEASUrement:IMMed:SOUrce<x> command.
NOTE. A change to HORizontal:MAIn:SCALe or CH<x>:SCALe will not
necessarily ha
ve taken affect if immediately followed by this command.
NOTE. Before using this query, you should make sure the prerequisites a re
completed. (S
