Data Flow - Keithley 6430 Instruction Manual

5-26 Source-Measure Concepts
Data flow
Data flow for front panel operation is summarized by the block diagrams provided in
Figure 5-15. Note that if REL is enabled, the result of the rel operation is sent to the other
blocks.
NOTE
With Math (FCTN) and Limit Tests (LIMITS) disabled (Figure 5-15A), the SourceMeter
displays the measurement readings. If the data store is used, these readings are also stored in
the buffer for later recall. Statistical data for these readings is also available upon recall.
Figure 5-15B shows data flow when Math or Limit Tests is enabled. If Math is enabled, the
result of the math operation is displayed. If Limit Tests is enabled, the raw reading along with
the results of the tests (pass or fail) is displayed. As in the previous case, these readings can also
be stored in the data store.
Figure 5-15C shows data flow when both Math and Limit Tests are enabled. The Math oper-
ation is performed first, and then limit tests are performed on that math result. The result of the
math operation and the result of the limit tests (pass or fail) are displayed. As shown, these
readings can also be stored in the data store.
See Appendix C for remote operation data flow information.
