Logic Analyzer Probing Support Products
USB - Embedded
Debugging of embedded 2-wire USB connections got you down?
No provision made on your motherboard for connection of an analyzer probe?
Never fear! Our USB-2BUF product attaches to the USB signals on your PCB with minimal additional loading and signal distortion,
buffering the signals and facilitating signal monitoring through use of a protocol analyzer, logic analyzer preprocessor or oscilloscope.
Simply solder the three signal leads to tap onto the D+, D- and Ground signal traces on your PCB;
no breaking of any PCB traces is required.
All USB2.0 signaling rates are supported: Low (1.5 Mb/s), Full (12 Mb/s) and High (480 Mb/s) speeds.
The USB-2BUF is USB powered (amazingly enough)!
The USB-2BUF comes equipped with two 1-meter standard USB2.0 A-B cables;
one cable provides power to the unit,
the other cable communicates the buffered PCB signals to the protocol analyzer, logic analyzer preprocessor or oscilloscope.
