Table A-1: M9110E Setup Variables, Revision C.8
Please note that variables listed below under “Setup Variables Available Through serial I/O”
should not be changed unless specifically instructed by Teledyne-API customer service or
engineering! Changing those variables may cause significant problems with analyzer
performance. Only those variables listed under “Setup Variables Available through Front
