40. Test Times and Analysis SQN 1010 ---- around 5-6mins SQN1110 ----- from 2-5mins depending on design SQN1130 ------ as of 11Sep07 6mins on SQN 4.2.1. firmware Goal is to beat SQN 1110. Analysis of Test Times :- a) 70% spent on Calibration b) 20% on Rx Verification c) 10% on Tx Verification LP’s niche is to optimize the Calibration time. This enables you to have an unfair advantage over others.
