Saving measurement results into USB memory
You can save measurement results obtained by the E4981A into USB memory 
as .CSV files. You can later load your saved files into an application program 
running on a PC. 
Before saving measurement results into USB memory, you need to complete 
some tasks preparatory to initiating measurement so that the data buffer 
memory contains the necessary data. For more information, see “To save 
measurement results into USB memory:” on page 88. 
Measurement result format
Measurement results are output in the format shown in Table 4-10.
The Data A and Data B fields of a measurement result file differ depending on 
whether the “effective digits” setting is on or off (controlled by the 
:FORMat:ASCii:LONG command). 
Data A
Outputs the measurement data for the primary parameter. 
The Data A field uses the following two different fixed-length ASCII formats: 
Data buffer 3 is used to perform save data operation through front panel 
and web server. Also, it is not possible to load data through web server.
You cannot load measurement results from USB memory into the E4981A.
