User Manual 

4  The ESPRIT 2 Software 

42 

 

 

 

 

 

 
 

 

 

 

   

The product registration is only 

valid for the specified system number. 
The system number of the current 
hardware is also listed in the product 
registration area. 

Export system files.

 This dialog allows for export all 

system relevant setting files as a .zip file. 

Product information.

  The current version of the 

ESPRIT software is displayed here. Please relay this 
information to Bruker Service upon service enquiry. 

Product registration.

  The product registration area 

shows  the  owner’s  registration information. Further 
details can be accessed by clicking on the 

 

button. This will launch the PDF reader to show the 
current product license. If a new license file is 
issued, the file in the ESPRIT software can be 
updated by clicking the 

 button. A copy of 

the license file is stored to the QUANTAX server’s 
profile folder. The license will be checked 
automatically by every time the ESPRIT software is 
started. 

 

Devices.

  The assignment and setup of the X-ray 

spectrometer(s) and other devices are normally only 
performed during system installation.  

The assignment is completely automatic. Each 
detector to be assigned must be connected to either 
Bruker MegaLink port, a RS232 port, an USB port or 
via Ethernet of the QUANTAX server and powered 
on when the 

 button is clicked. All available 

ports are automatically scanned for valid 
connections.  Once the spectrometer is located, the 
ESPRIT software must be restarted in order to 
register the newly found device. 

After the restart of the ESPRIT software the available 
detectors are listed within the 

Configurator  bar

 

(refer to section 4.5). 

 

 

Fig. 4.7-2 Detector data dialog 

 

 

Clicking the 

 button opens a dialog for setting 

the type  of spectrometer, the type of the radiation 
entrance window, and the  geometry parameters. 
These entries are loaded from the detector 
description file or the detector data sheet.  

The motorized detector support can be activated 
here. In order to record the acquisition position, click 
the 

 button and follow the wizard. 

The 

Command

  field next to the 

  button 

performs low-level command functions. This is for 
troubleshooting purposes by system engineers.
