Entering System Data for
a Channel/Path - CHx-
SYSTM
The CHx-SYSTM submenu is used to enter system parameters for the
individual channels/paths. When channels/paths operate separately,
the AT868 uses the system parameters in this menu. When channels/
paths are averaged together, the AT868 uses parameters selected in
the GLOBL-SYSTM submenu.
While following the programming instructions, refer to Figure A-1 on
page A-1 in Appendix A, Menu Maps. Remember to record all
programmed data in Appendix C, Data Records.
