Saving a File

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.

Verifying Trace 1

When operating in dc coupled mode, ensure protection of the input mixer by limiting the input level to 0 Vdc and +30 dBm.

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.
