activates the automatic leveling control (ALC) function for
internal
(INT)
leveling or external (XTAL or MTR) leveling.
The external leveling input (located on the rear panel of the
analyzer) can be used with a power meter or crystal that has
a positive or negative voltage output. See specifications
and characteristics in your calibration guide for the leveling
input characteristics. External leveling increases the
amplitude accuracy by improving the effective source match.
The meter (MTR) position narrows ALC loop bandwidth so
an HP power meter can be used.
