Using External Leveling (N5173B/83B Only)

CAUTION
While operating in external leveling mode, if either the RF or the DC connection between
the signal generator and the detector is broken, maximum signal generator power can
occur. This maximum power may overstress a power–sensitive device under test.
These settings do not
change the output
power amplitude of the
signal generator, they
only let you modify the
front panel display
amplitude value so it
closely approximates
the power level
measured at the
output of the
coupler/splitter. See

Atten Hold sets to On and grays out (inactive) with Ext Detector selection.
When re–selecting Internal, the softkey becomes active, but attenuator hold
remains on. If desired, manually set it to off.
With the Ext Detector selection, Set Atten has no effect on the output power
level. During external detector use, use the attenuator to keep the ALC
power level at approximately 0 dBm when using negative dBm power
levels. See
This softkey works with only the Ext Detector selection. It uses 16 dB
as its zero reference point.

Opens a menu in which you can specify the manner in which
power is set. Power setting can be optimized for different
parameters.
Select Optimize S/N to maximize the signal to noise
performance in the resulting signal.
Select Optimize Harmonics to minimize the amplitude of
harmonics in the resulting signal.
