State Analysis
This chapter explains how to configure the PCI Active Analysis
Probe to perform state analysis on the PCI Local Bus. The
configuration software on the flexible diskette sets up the format
specification menu of the logic analyzer for compatibility with the
PCI Local Bus. The next chapter explains how to configure the
PCI Active Analysis Probe to perform timing analysis.
Installation Quick
Reference
The following procedure describes the major steps required to
perform measurements with the PCI Active Analysis Probe
module.
1. After removing the probe tip assemblies, plug the logic
analyzer cables into the Analysis Probe cable headers.
See page 11 of this manual for details.
2. Set the STATE/TIMING switch to STATE. The State
LED will be lit.
3. Power off the target. Install the PCI Active Analysis
Probe module into a slot in the target PCI Local bus.
Then power on the target.
Load the logic analyzer configuration file by loading the
appropriate file from the Analysis Probe interface diskette. See
page 16 of this manual for details.
Using the front panel
switches in state
mode
The front panel switches are only useful in STATE MODE. They
are clearly marked on the front panel.
• The Parity On switch controls parity checking. If the Parity
On LED is lit then parity checking will be done.
• The No Wait switch controls the acquisition of WAIT cycles.
If the No Wait LED is lit then no wait cycles will be acquired.
• The No Idle switch controls the acquisition of IDLE cycles. If
the No Idle LED is lit then NO IDLE cycles will be acquired.
• The TDO-TDI switch from the top connects TDO to TDI. If
the switch is to the rightmost position TDO is connected to
TDI.
• The State/Timing switch controls the on board latches.
When the State LED is lit then the PCI Active Analysis Probe
is in State mode.
Refer to page 10 for more details on the LEDs and switches.
