LO Leveling Functions The first four softkeys specify different methods of leveling for the 83621B
LO source.
If
{LO LEVEL / SYSTEM} is selected, leveling of the LO source (83621B) is
controlled entirely by the 8510XF system. This is the normal operating
mode.
NOTE The remaining “LO LEVEL” selections are provided as a convenience for
use in unusual applications; they are not recommended for normal operation
of the 8510XF.
If
{LO LEVEL / INTERNAL} is selected, the LO source performs its own leveling,
using an internal detector.
