3.4.2.2 File Saving/Loading Method
The 3943B monitoring receiver provides data file saving/calling function. File saving is to store the
measurement data in a file according to the agreed format (for example: *. png, *. dat). File call refers to
opening the selected data file and refreshing display information, such as measurement parameters and
list parameters, so as to facilitate the observation and evaluation by users.
According to different information types and management methods, the 3943B monitoring receiver
provides seven kinds of file saving functions and six kinds of file calling functions. The seven types of
files that can be saved are: reset status file, trace file, image, audio, storage table, suppression table and
IQ data file. The file types that can be called are: reset status file, trace file, storage table, suppression
table, antenna factor and audio file. Users only need to enter the corresponding menu to pop up a dialog
box, and specify the file name to be saved or select the corresponding file, so as to save and call the file.
Specific instructions are as follows:
For the saving and calling of reset status file, refer to 3.4.1 ―Reset status storage/ calling‖;
