The 7530 High-Speed Low-Current 8×12 Matrix Card is a plug-in switching module engineered for precision signal routing in semiconductor characterization and test environments. It delivers high-speed, low-current signal switching across an 8-row by 12-column crosspoint matrix, with guarded triaxial paths optimized for I-V and C-V measurements on sensitive devices under test.
