NOTE You should notice that the trace you saved, in this example trace 3, is
loaded to trace 2. If you wish to verify this condition, remove the signal
input. For Agilent E4401B and E4411B, press
Input/Output, Amptd Ref
On Off (Off), for all other models, press Input/Output, Amptd Ref Out On
Off (Off).
Note that when a trace is loaded, it is placed in view mode. To see that
trace 2 is in view mode, blank traces 1 and 3 by pressing View/Trace,
Trace 1, Blank, Trace 3, Blank. Then press Trace 2. Notice that trace 2 is
the only trace displayed in view mode (the view key is selected, and the
trace is not sweeping). Your display should look similar to Figure 2-12.

CAUTION When operating in DC coupled mode on spectrum analyzers with
Option UKB, take care to protect the input mixer by limiting the input
level to O VDC and +30 dBm.
NOTE When loading Limits files, be sure you have selected the appropriate X
Axis Units: frequency or time (Display, Limits, Properties, X Axis
Units). If you are in time X-Axis Units, and you load frequency limits,
all current limit line data will be erased and the analyzer will switch to
the frequency domain. The reverse of the this situation also holds true.
