Data flow
Data flow for front panel operation is summarized by the block diagrams provided
in Figure 6-20. Note that if REL is enabled, the result of the rel operation is sent to
the other blocks.
NOTE See Appendix C for remote operation data flow information.
With Math (FCTN) and Limit Tests (LIMITS) disabled (see Figure 6-20A), 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 6-20B 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 6-20C shows data flow when both Math and Limit Tests are enabled. The
Math operation 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.
