The  upper  section  of  the  GUI  presents  the  ESCA  device  specific  commands  (see  the 
“ESCA Setup” section for details). 

Just  below  you  can  find  some  estimated  statistic  values  on  the  input  signal  (see  the 
“Statistic Data” section for details), while on the right there are the controls to associate 
an  oscilloscope-like  trace  (beam)  with  a  specific  input  signal  in  the  visualization 
window (in the case of ESCA devices, there is only one  input channel available). See 
the “Trace Visualization” section for details. 

On the right there is an estimation of the input bitrate. 

In the bottom you can find, in addition to the “Open Config” button already described 
in the previous section, the following buttons: 

 

Connect

 – Starts the communication with the ESCA hardware. 

 

Show

 – Displays the data visualization window. 

 

Save

 – Save data. 

In  the  bottom-right  corner  there  is  a  drop-down  list  of  the  serial  numbers  of  all  the 
recognized ESCA devices connected to the PC. 

NOTE:  Multiple  instances  of  the  software  can  run  on  the  same  PC  enabling  to  control 
several  ESCA  devices  connected  to  the  same  PC.  If  more  than  one  ESCA  device  are 
connected, you must first choose the correct device Serial Number to be controlled.

 

To start acquiring data, click on the “
