JTAG Technologies BV has announced the availability of a compact, mixed-signal (digital, analog and frequency) measurement module, the JT 2149/DAF. The module is the first such module to provide both digital and analog test access to PCBs via the company's QuadPod signal conditioning interface.

The module is designed to slot into JTAG Technologies' 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.

The JT 2149/DAF module includes 16 dual-purpose digital pins capable of digital I/O stimulus and response at voltages of 1V to 3.6V plus frequency measurements of up to 128MHz on any pin. It has 12 additional analog measurement channels that can capture values from 0 to 33V with better than 10mV resolution. An additional channel is available as a clock generator, programmable up to 64MHz.

The JT 2149/DAF can be controlled through an interactive panel (virtual instrument) within JTAG ProVision as well as through Python scripts. A full Python API is included as part of JTAG Technologies current ProVision releases.

The modules are now available.
