Hybrid Characterization and Gain Scan Procedures

1. Put heel grounding straps on both feet.  
2. Test grounding straps at ground test station.  
3. Connect hybrid to ARC front end board.  
4. Turn on low voltage power supplies. Adjust each if needed until it reads ~5.0V.  
5. Start the ARC software.  
6. Click on the initialize board button. Enter hft_3021671300XXX where XXX is the last 3 digits of the hybrid serial number.  
7. From the deep tests menu select pipeline. Set peak mode; with inverter on and number of events to 200. Run the test and write the data to disk. Move the .dat file to the hft_3021671300XXX subdirectory  
8. From the deep test menu select pulse shape. Set peak mode with inverter on. Set rms to 1000, max latency to 18, min latency to 13 and mip to 0. Run test and write data to disk.   
9. Rename the file PSh_hft_3021671300XXX_PeakIon.dat PSh_hft_3021671300XXX_PeakIon_0_0MIP.dat  
10. Repeat step 2 and 3 with mip set to 0.5, 1.0, 1.5, 2.5 and 3.0 each time renaming the file PSh_hft_3021671300XXX_PeakIon.dat to PSh_hft_3021671300XXX_PeakIon_Y_ZMIP.dat where Y.Z is the value of mip.  
11. Move all PSh_hft_3021671300XXX_PeakIon_*.dat  files to the hft_3021671300XXX subdirectory.  
12. In the hft_3021671300XXX subdirectory copy PSh_hft_3021671300XXX_PeakIon.dat to PSh_hft_3021671300XXX_PeakIon_2_0MIP.  
13. Start Root and run the characterization and gain scan macro.  
14. Run the script which enters the Root files into the database.  
15. Exit the ARC software. Turn off the power supplies. Disconnect hybrid from ARC front end board.
