---+ muon_trg trigger inputs,measured 23.4.2009

All the inputs were examined with Signature and Toggling signal.

Internal TTCmi and external BEAM1 LHC clock was used -the phase measurement finished with the same results.

Strange shape of 0MLH signal: it is shifted in respect to the others, second jump (after 25ns)in ADC values is missing.

The delay circiut anomaly (25ns) seen on all the graphs.

The pictures from phase measurements are included.

| *signal*  | *CTPin* | *Signature* | *DIMnumber* |
| [[%ATTACHURL%/MUH.ps][0MUH]] | 10 | 110 | 1 |
| [[%ATTACHURL%/MUL.ps][0MUL]] | 12 | 111 | 2 |
| [[%ATTACHURL%/MLH.ps][0MLH]] | 13 | 112 | 3 |
| [[%ATTACHURL%/MLL.ps][0MLL]] | 9 | 113 | 4 |
| [[%ATTACHURL%/MSL.ps][0MSL]] | 11 | 115 | 6 |

*Conclusion:* all the inputs need to be strobed with Negative clock edge (for BUSY BC_DELAY_ADD=0).
