The Wayne Kerr 1905X Probe Kit allows the 1905A SMD Probe Leads to be used with analyzer models that do not have a 2-terminal setting for their front panel BNC connectors. This is achieved by using the included model 1023 4 into 2 BNC Adaptor. This kit is required when using 6500 or 4300 analyzers.

The 1905X Probe Kit includes the 1095A SMD Probe Lead Set, which features two sprung needle probes. The probes are used to access surface mounted devices on circuit boards; they are also suitable for interfacing to hybrid components and chip components on tape.
