Logic Analyzer Probing Support Products
Monitoring embedded standard USB2.0 signaling
Our USB-2XT and USB-3ZT analyzers can monitor embedded standard USB2.0 (HS/FS/LS) signaling
when used with our USB-2BUF embedded buffer unit (described below). Alternatively, use can be made of our USB-HSIC-BUF embedded buffer unit
(also described below) with the USB-3ZT when monitoring embedded standard USB2.0 FS & LS signaling.
Monitoring embedded IC_USB signaling
Our USB-2XT and USB-3ZT analyzers can monitor embedded IC_USB (FS/LS) signaling
when used with our USB-2BUF embedded buffer unit. Alternatively, use can be made of our USB-HSIC-BUF embedded buffer unit
(for USB-3ZT only).
Monitoring embedded HSIC_USB signaling
Our USB-3ZT analyzer can monitor embedded HSIC_USB (HS) signaling when used with our USB-HSIC-BUF embedded buffer unit.
USB-2BUF Embedded Buffer
Debugging of embedded USB2.0 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.
Supports monitoring embedded standard USB2.0 signaling (HS/FS/LS) and IC_USB signaling (FS/LS) as described above.
All USB2.0 signaling rates are supported: High (480 Mb/s), Full (12 Mb/s) and Low (1.5 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.

USB-HSIC-BUF Embedded Buffer
Supports monitoring embedded standard USB2.0 (FS/LS) signaling and IC_USB (FS/LS) signaling, as well as HSIC_USB (HS) signaling,
when used with our USB-3ZT analyzer as described above.
(Note that monitoring standard USB2.0 HS signaling is not supported.)
All USB2.0 signaling rates are supported: High (480 Mb/s), Full (12 Mb/s) and Low (1.5 Mb/s) speeds.
