    Remote operation HSCSD Subsystem GPIB Commands HSCSd:MASTer:UPLink:AMPLitude Description This sets the expected input level of the master TCH. In standard mode, this sets the master’s uplink amplitude control to MANUAL. In compatibility mode, if the master’s uplink amplitude control is set to MS TX LEV then an error message Can’t change setting while MS TX Lev mode is selected.
