<p>I have tried the latest version ( 26 ) of the FEE64 code and carried out some measurements of the Fast Trigger delay from the Pulser signal ( not the Pulser Trigger out ) and observed the following.</p> <p>The pulser gives a centroid of 28217 in the histogram.</p> <div> </div> <table width="410" cellspacing="1" cellpadding="1" border="1" height="202"> <tbody> <tr> <td width="111">Threshold setting</td> <td width="286">Delay observed at MACB Fast Trigger output (nS)</td> </tr> <tr> <td width="111">0x40 </td> <td width="286">no Trigger</td> </tr> <tr> <td width="111">0x38</td> <td width="286">no Trigger</td> </tr> <tr> <td width="111">0x30</td> <td width="286">no Trigger</td> </tr> <tr> <td width="111">0x28</td> <td width="286">1200 to 1800</td> </tr> <tr> <td width="111">0x20</td> <td width="286">690 to 860</td> </tr> <tr> <td width="111">0x18</td> <td width="286">505 to 600</td> </tr> <tr> <td width="111">0x10</td> <td width="286">320 to 385</td> </tr> <tr> <td width="111">0x8</td> <td width="286">210 to 270</td> </tr> </tbody> </table> <p>This seems to me to be sensible as the discriminator is only a very simple comparator.</p> <p>The OR64 ( 0xE ) signal works as True Fast NIM Logic. The OR16s ( 0xC ) logic works as inverse Fast NIM.</p> <p>The OR64 is derived from the individual masked discriminator outputs. By default the Mask is not set.</p> <p> </p>
