Multi-function JTAG Module Addresses Analog Testing
Multi-function JTAG module.
Eindhoven, The Netherlands — JTAG Technologies has introduced the JT 2149/DAF, a compact, mixed-signal (Digital/Analog/Frequency) measurement module. The module is the first unit of its type to offer both digital and analog test access to PCBs using JTAG Technologies' widely-used QuadPod signal conditioning interface.

The module has been designed to slot into the company's 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 of the JT 2149/DAF module include 16 dual-purpose digital pins capable of digital I/O stimulus and response at voltages of 1.0 to 3.6V plus frequency measurements of up to 128MHz on any pin. There are 12 additional analog measurement channels which can capture values from 0 to 33V with better than 10mV resolution. One further 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.
