Introduction The USB Analysis Probe module provides a complete interface between any poi nt on the USB and an Agilent Logic Analyzer. T he Analysis Probe interface receives the USB serial bit stream and converts it to an understandable parallel bus that is then acquired by the logic analyzer.
• The State Analysis chapter explains how to configure the USB Analysis Probe to perform state analysis on your USB . • The Timing Analysis chapter explains how to configure the USB Analysis Probe to perform timing analysis on your USB .
Analyzing the Universal Serial Bus This chapter introduces you to the USB Analysis Probe and lists the minimum equipment required and accessories supplied for Universal Serial Bus analysis. This chapter also contains information that is common to both state and timing analysis.
The minimum equipment required for analysis of a Universal Serial Bus consists of the following equipment: Minimum Equipment Required • A 166x, 167x , 1680/90, 1671x , 1674X, 1655x or 1675x logic an.
The following explains how to connect the logic analyzer to the USB Analysis Probe for either state or timing analysis: Connecting to the USB Analysis Probe 1. Remove the probe tip assemblies from the logic analyzer cables. 2. Plug the logic analyzer cables into the USB Analysis Probe cable headers as shown in the appropriate following tables.
The logic analyzer can be configured for USB analysis by loading the USB configurati on file. Loading this file will load the Universal Serial Bus inverse assembler and configure your logic analyzer for USB analysis. Setting up the Analyzers installed in the 16500 mainframe.
configuration file yourself, see table below for a list of analyzers and corresponding configuration files. Note: The Logic Analysis System’s Operating System must be version A.01.40.00 with patches 034 and 035 or higher to be compatible with the software provided on the installation diskette for the 167xx.
the menu bar at the top of the screen and select the decoder from the list. After loading the configuration file of choice, go into the format specification of the configuration by choosing Setup from the menu bar and then selecting Bus/Signal in the drop down menu.

picture; please choose the appropriate decoder for the trace you are working with. After the decoder has loaded, select Preferences if required, from the overview screen and set the preferences to their correct value in order to decode the trace properly.
The Format Menu The USB Analysis Probe diske tte sets up the format menu as shown in the followi ng table. This format is the same for both Timing and State Analysis.
The STAT variable is used by the USB inverse assembler to decode USB transactions. It should not be changed or deleted from the format m enu. The STAT variable The ADDR and DATA variables The ADDR variable is the address and endpoint as decoded from the USB serial bit stream.

3. Pass a “POSSIBLE BAD EOP” status to the Analyzer. A status of “POSSIBLE BAD EOP” should be treated as cautionary and the user would be advised to view the received signals in timing mode by doing the following. 1. Attach POD 3 of the analyzer to POD 3 of the USB Analysis Probe.
Sequence 2 1. Detection of a PREAMBLE - switch to low speed 2. Look for IN packet and a following DATA packet and then switch back to high speed. If a DATA packet is not received wit hin the time-out period (18 bit times), the Analysis Probe will switch back to high speed.
State Analysis This chapter explains how to configure the USB Analysis Probe to perform state analysis on the Universal Serial Bus. T he configuration software on the flexible diskette sets up the format specification menu of the logic analyzer for compatibility with the USB Analysis Probe.
Probe OUT connector can be connected down stream to either a Hub or device or it can be left unconnected. 4. Turn on the logic anal yzer so that the VCC and READY LEDs on the USB Analysis Probe are lit. NOTE: Connect the USB Analysis Probe to the USB wire as described in step 2 prior to powering up the logic analyzer.
Analysis Probe related error messages The following Analysis Probe related error messages are reported by the USB inverse assembler. FAILED TO IDENTIFY PID This error will be reported by the inverse assembler if the USB Analysis Probe hardware reports a status code that is undefined.
The USB Analysis Probe will also detect invalid PIDS, bad PIDS and SOF tokens s ent at slow speed. The Analysis Probe implements an error summary status called ANY ERROR, this st atus will be sent to the Analyzer if any of the above error conditions is detected by the Analysis Probe.
Timing Analysis Pod 3 of the USB Analysis Probe contains signals that describe in more detail the actual state of the USB wire. Installation Quick Reference The following procedure describes the major steps required to perform timing analysis measurements with the USB Analysis Probe module.
Acquiring Data Touch RUN and the logic analyzer will begin to acquire data. The analyzer will continue to acquire data and will display the data when the analyzer memory is full, the trigger specification is TRUE or when you touch STOP.
