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.
