JTAG Technologies JT 2149/DAF measurement module

JTAG has introduced the JT 2149/DAF, a compact, mixed-signal (digital/analog/frequency) measurement module that is the first unit of its type to offer both digital and analog test access to PCBs via the company’s QuadPod signal conditioning interface.

The module has been designed to slot into the regular QuadPod transceiver system as used by the DataBlaster series of boundary-scan/JTAG controller hardware. When connected to a circuit board via edge connector or test fixture/jig test pins, the module enhances standard digital boundary-scan tests by enabling a series of analog and frequency measurements to be made.

Capabilities include 16 dual-purpose digital pins capable of digital I/O stimulus and response at voltages of 1.0 to 3.6 plus frequency measurements up to 128 MHz on any pin. Twelve additional analog measurement channels can capture values from 0 to 33 V with better than 10 mV resolution. One further channel is available as a clock generator, programmable up to 64 MHz.
