The 6500-CX must be in Auto mode in the Insertion Gain screen and running
an aided measurement. At this time, the 6500-CX cannot establish a real-time
connection in the SPL Testing screen, or while the analyzer is in manual mode
in the Insertion Gain screen.

CONNECT button will estab-
lish a real-time connection with the current REAR curve.
