3.5 Short “LEASH” probes
The standard product includes 4 “LEASH” probes connected to this Interposer product. These
short probes are soldered directly onto the interposer and interface the Interposer to the Passive
probes that connect to the logic analyzer. These “LEASH” probes are to allow the user to easily
install and remove the Interposer product in their system with out the added weight of the
passive probe attached. There may be other probing options in the future. Contact Nexus for any
updates.
Figure 1 below shows the location on the Interposer of the LEASH probe connections.

The four (4) each, 1 foot long, “LEASH” probes that are soldered onto the Interposer are in turn
connected to either a NEX-PRB1X-T or NEX-PRB2X-T probe. The NEX-PRB1X-T or NEX-
PRB2X-T probe in turn connects to the input of the logic analyzer modules. The connection
between the LEASH Probes and the logic Analyzer is a Samtec connector with a pin out as
shown below on the LEASH probe. Refer to 3.2 to determine if a NEX-PRB1X-T or NEX-
PRB2X-T connects to each LEASH probe.
