Protocol Errors
The TA700/800 monitors over 50 different protocol errors and detects all of them
automatically every time a data capture is made. The detected errors are displayed in
red on the output display provided, that the ERROR signal has been selected for
display using the Active Signals dialog box. To include the protocol errors on the
display click the Setup Screen button and then make sure that ERROR has been
included in the Active Signal list.
Protocol Error A predefined trigger selection for Protocol Error is included as one of the
trigger choices in the Data Capture & Trigger On menu in the Easy
Mode. For Advanced mode the Protocol Error is also listed as an input of
each sequencer state to cause the conditional jump or triggering selection
as well. You may use the Protocol Error selection in the easy mode to
trigger on protocol errors without any special setup required.
To limit the number of errors that can cause a trigger you may mask out the unwanted
protocol errors.
