FS2004 32-bit CardBus Analysis Probe and Extender Card

The CardBus analysis probe and extender card provides three functions:

1. Acts as an extender for a CardBus module beyond the host system, and provides access to both sides of the module for easy debug. Pads are available to add series resistors if necessary to compensate for the extension of your card.

2. Provides an electrical and mechanical interface to Agilent logic analyzers for passive CardBus bus analysis. The passive logic analyzer termination presents a single electrical load on the CardBus via low capacitance (10pf), high impedance terminators, and also provides a matched impedance to the logic analyzer. The analysis probe includes four, 40 pin logic analyzer connectors. Software is included for full CardBus protocol analysis.

3. Provides test points to measure the power and signal fidelity of the CardBus bus.

The CardBus protocol decode software executes in your Agilent logic analyzer. In State Analysis mode, the analyzer master clock is derived from the CardBus clock. The bus protocol decode software decodes the key CardBus bus signals and presents a readable display that lists the transaction type, address, data, and key status conditions, such as wait states and retries.

The software also supports user-defined symbols that can be easily added to the state listing display. User-selectable post-processing filters allow the display of only chosen transactions.

To assist with triggering, pre-defined resource terms are included and can be used to prevent WAIT and IDLE states from being acquired, thus saving trace memory and providing an easier-to-read state display.

In Timing Analysis mode, the logic analyzer provides the master clock to make precision timing measurements. All signals are also available for probing with an oscilloscope or high speed timing analyzer.

FuturePlus Systems offers a CardBus triggering application note, available in the FS2007 Library.
