Description
For the
HP
8590L or HP 85913: Option 010 or 011 for the HP
859OL
and HP 85913 provide
internal (INT), crystal (XTAL), and meter (MTR) leveling.
n
SRCALC INT activates internal leveling.
n
SRCALC XTAL activates external leveling. The external leveling input (EXT ALC INPUT) is
located on the rear panel of the spectrum analyzer. Positive- or negative-polarity detectors
are supported. External leveling increases the amplitude accuracy by improving the effective
source match.
n
SRCALC MTR narrows loop bandwidth so Hewlett-Packard power meters can be used for
external leveling.
Fbr
the HP 859OL and HP
8591E
only: The functions of SRCALC and ALC
KTR
INT
XT&
are
identical.
For the
HP
85933, HP 85943, HP 85953, or HP 85963: Option 010 for the HP 85933,
HP 85943, HP 85953, or HP 85963 provide internal (INT) and external (EXT) leveling.
