CB53 4-Wire CB Board Conversion Set

Configuration

Sold as a set of two boards, the CB53 is a special connector motherboard that will convert a top-mounted standard 64-pin connector board test fixture into a 4-wire test fixture. Conversion is valid when the UUT connects directly into the standard board rather than via a flying lead or adapter cable and eliminates the need to otherwise create custom 4-Wire test fixtures. In addition to CableEye software, dated Jan. 2019 or later, the CB53 requires a tester with 4‑wire measurement capability, a mating connector board, and an expansion module. As with any 4‑wire measurement, twice the number of test points is required than for standard 2‑wire measurement, therefore an expansion module is necessary. Ribbon cables to connect the CB53 to each bank of the expansion module are included.

Note that this is a ‘Plug & Play’ interface, requiring NO additional 4-wire fixturing to operate.

Software

Requires the 4-Wire Kelvin option and software release dated Jan. 2019 or later.

Voltage Rating

Rated to 800 Vdc/ 500 Vac
Can be certified for operation at the maximum rated voltage for a service fee (Item 626).

Application

Make 4-wire measurements from the signal entry point of any existing CAMI 2-wire 64-point board and closely approximate a true 4-wire test. These are the advantages:
