12. ation of 242 maximum run length This was a conscious design decision that was made by balancing the tradeoffs of possible backplane loading versus signal acquisition accuracy By not introducing signal buffers it is possible using the NEX SIA adapter to see the exact timing relationships and signal waveforms from the backplane It is also much easier to connect pattern generators to the backplane since buffer direction is not a concern It is believed that the signal loading of the TLA600 700 or 92496 acquisition cards is low enough so that VME signal degradation will not occur The NEX VME Adapter Board was designed so that the run lengths for critical signals and those with the highest activity levels such as the address data bus are as short as possible This should help greatly in retaining signal integrity B 2 Patch Areas If signal loading or reflection does become a concern the capability exists to add series resistors to any VME signal Patch areas have been provided next to each TLA600 700 A96 connector consisting of two rows of plated through holes These areas outlined on the silk screen and labeled as Nxx are suitable for individual resistors or resistor networks To add a series resistor simply cut the trace of the desired signal on the component side of the board and solder the resistor between the two feed throughs B 3 Prototype Area A 2 inch by 2 inch grid of holes can be used as a prototype area This area can
