<p>Firmware version8 number 8 has an OR64 added which can be routed, using the Local control, to the Trigger output and hence seen at the front panel Fast NIM LEMO00 connector.</p>
<p>The OR64 is the OR of all the ASIC Discriminators. Each rising edge of a discriminator signal will give a 10ns pulse on the Fast NIM signal. If two coincide there will be one pulse.</p>
<p> The attached 'scope photograph shows the pulser trigger output ( orange trace ) and the OR64 signal ( blue trace) .</p>
<p>The delay shown is 98nS. </p>
<p>nnaida2 has no ASICs mounted so this timing is for the VHDL and MACB system. </p>
<p>Further tests will be run with the full T9 system ( nnaida11 -> 14 + detector ) and this entry updated with that result.</p>
