本文针对涡流无损检测中存在的普遍问题,采用两片新器件MAX038组成程控宽带正交信号,在智能涡流无损检测仪中较好地解决了信号源及相关检测电路中参考源的问题。
In this paper, aiming at the common problems existing in eddy current non-destructive testing, two pieces of new device MAX038 are used to form program-controlled wideband orthogonal signals. The problem of reference source in signal source and related detection circuit is solved well in intelligent eddy current nondestructive testing instrument.
