Company Profile

JDI provides high performance, portable/bench top digital and analog testers that are versatile and simple to use, and test a wide variety of device families and circuitry, at low cost.


JD Instruments was formed in 1999 to manufacture and sale a family of rugged, portable test systems that have been under development since 1991.

These systems have gone through several generations of refinements, and have been used in testing a wide variety of device families.  The digital tester has been used to test numerous memories, micro-processors, ASICs, and FPGA's.  The analog tester has been used to characterize many types of transistors, test structures, Op Amps and analog circuitry.

From conception the systems have been designed to be bench top/ portable with performance similar to large console testers.  This has been achieved through modular architecture and several custom ASIC's.
