Function description:
Supports 192/128 array probe, 4D probe, phased array probe, bi-plane probe, and other
nominal probes, etc.
Implements the switch of 192 array probe within the probe. Probe board only supports 128
channels.
Probe board contains three 260pin Mini probe sockets.
Supports the retrieving of three probes’ IDs and the switch among three probe socket. ID
recognition and the circuit of probe switch are independent to each other.
