Abstract
The logic analyzer interface assembly connects to a unit under test (UUT). The interface assembly includes an interface board having interface contact points matching the pattern of the UUT contact points. The interface board is mounted to a transfer interface including a probe plate and multiple spring loaded probes extending through the probe plate. The probes contact the UUT contact points at one end and the interface contact points at the other end. When assembled, the UUT and interface assembly form a sandwiched testing assembly that can be inserted into a chassis to aid in approaching an “at speed” observation opportunity.
Claims9
A logic analyzer interface assembly for use with a unit under test (UUT) having a plurality of UUT contact points in a predefined pattern, said interface assembly comprising:
- an interface board having a plurality of interface contact points on a primary side arranged to match said predefined pattern of said UUT contact points and a plurality of analyzer connectors on a secondary side, wherein said contact points are electrically connected to said analyzer connectors;
- and
- a transfer interface including:
- at least one probe plate;
- a plurality of probes extending through and floating freely in said at least one probe plate, each of said probes including a barrel and a single spring loaded plunger extending from one end of said barrel, wherein said plunger of each of said probes contacts said UUT contact points and said barrel of each of said probes contacts said interface contact points on said interface board;
- and
- at least one probe retention plate positioned over at least one side of said at least one probe plate for retaining said probes in said probe plate.
