JT 5705/USB

Compact mixed-signal desktop boundary-scan controller.

With its unique combination of 2 TAPs and 64 mixed signal I/O channels the desktop JT 5705/USB is ideal for hardware validation or small-scale production test. Use the IO (56 digital and 8 analog channels) to measure power supplies, clock frequencies, test DACs and ADCs and improve coverage to test points and connectors.

Maximum TCK speed is 15 MHz and all voltages are fully programmable.

Special fixture versions of the JT 5705 are available: JT 5705/BO and JT 5705/IB. Also a rack mount version is available JT 5705/RMIc.
