Preliminary Using External Leveling (N5183A Only)
Using External Leveling (N5183A 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.
External leveling lets you move the ALC feedback source closer to the device under test (DUT) so
that it accounts for most of the power uncertainties inherent to the cabling and components in a test
setup. Refer to Figure 5-16.
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.
Option 1E1 feature—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 page 100.
These settings do not change the output power amplitude of the
MXG, 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 page page 104.
This softkey works with only the Ext Detector selection. It uses
16 dB as its zero reference point.
