Advanced Topics 

This section describes advanced topics of the T940, giving more details than 
what were provided in previous chapters. Because references are made to 
DRS configurations, relevant API and ARI calls are both provided here. 

The topics covered include: 

•

  Jumping, Halting, Counting and Logging on Pass/Fail 

•

  Understanding Record Offset 

•

  Pause and Halt 

•

  Sequencer Operation Details 

•

  VXI Backplane Trigger Bus 

Jumping, Halting, Counting and Logging on Pass/Fail 
Conditions 

The T940 has extensive capability when it comes to Jumping or Halting on 
various Pass/Fail conditions in both Pipelined and non-Pipelined modes. The 
counting or logging of Errors in the Error Address Memory (EAM), Single 
Stepping and Record Modes will also be covered since they are interrelated. 

This section discusses these topics using the Soft Front Panel (SFP) but 

VXIplug&play

 API calls and Application Resource Interface (ARI) references 

are provided. 

Topics to be covered in this section include: 

•

  Coupling of signals between Sequencers for Linking and DRS 

Formation 

•

  Step Record Mode 

•

  Record Type 

•

  Counting and Logging Errors 

•

  Pipelining and non-Pipelining 

•

  Jumping or Halting on Pass/Fail conditions 

•

  Understanding Pass/Fail  

•

  Additional Pipeline Information 

•

  Valid Pass and Capture Fault 

•

  Additional Halt Information
