CSC40 Load Board

![]() |
The CSC40 load board is the only load board required for running Q2 self checks and calibration. It replaces Self Check 1, Self Check 2 and Calibration Mux load boards. When using the CSC40 with a PC-Host and Q2/52, the timing verification and all self checks may be run from a single command. Two set-ups are required with the Q2/62, one for the self check and another for calibration. Previously, four hardware set-ups were necessary and three of these set-ups required that the tester power be turned off. And, to comply strictly with Q2 specifications, each power down was to be followed by a 30 minute warm-up period. With the CSC40 load board, the tester needs to be powered down only once with a Q2/52 and twice with a Q2/62. The switching relays on the CSC40 load board are mounted in sockets to make replacement easy. The often troublesome buffer circuit used on older designs has been upgraded. |
