    The standard terminations on the digital lead sets can be pushed directly onto 25-mil pins. MicroGrippers or NanoGrippers may also be used to probe the test circuit’s pins. Teledyne LeCroy provides a selection of small, medium, and large grippers for various pitch sizes. A more complete selection of adapter probes is available for most chips from Emulation Technology Inc., Yamaichi Inc., and other manufacturers.
