Viewing Catalogs and Saving Files

Saving a File

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. Press

 

Input/Output, Input Port, Amptd Ref (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 4-7.

 

 

Figure 4-6. Verifying Trace 1

CAUTION

When operating in dc coupled mode, ensure protection of the input mixer by

 

limiting the input level to 0 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.
