PROM #3 in the Framework MTG Timing Specification File Timing Specification File Revision: 22-JUL-1994 PROM Timing Waveform Serial Number: 3N PROM 3 of the Framework MTG supplies the signals for MTG channels 17 through 24. All numeric data in all Timing Specification Files is in decimal. The PROM pattern in this file for 6 bunch on 6 bunch operation begins at address 100 and plays through address 651. This is 6 Beam Crossing Sections of 92 "Ticks" each. The PROM pattern in this file for 4 bunch on 4 bunch operation begins at address 1100 and plays through address 1655. This is 4 Beam Crossing Sections of 139 "Ticks" each. Revision Information: --------------------- This Rev L file is derived from the Rev K file. The only difference is that the L1 Triggers per Bunch DBSC Clock (Ch #19) has been shifted 4 ticks later. This Rev. M file is derived from the Rev. L file. The only difference is that Timing Signal #20 has become the Increment Transfer Number (part of the TAS Number) instead of the Increment Event Number signal. Rev. N file goes from 7 COMINT Clock cycles per 3.5 usec to 6 COMINT Clock cycles per 3.5 usec. Channel Function --------- ------------------------------------------------------------ 17 Timing Signal to control the Skip 2 Beam Crossings PAL. 18 Timing Signal to control the Skip 10 Beam Crossings PAL. 19 Increment the L1 Trigger per Bunch DBSC Scalers. 20 Increment the Transfer Number DBSC (part of the TAS Number). 21 Specific Triggers Fired Strobe waveform. 22 COMINT Clock. 23 First 4 "Ticks". 24 Last 4 "Ticks". ; ; Page 2 Beginning_of_Data_Section ; Framework MTG Channel #17 is used to control the Skip 2 Beam Crossings ; PAL.
