When the format is predefined the meaning of the individual bit fields, as well as the
interpretation of the content and even of the position and length of the bit fields depend
on other, preceding bit fields. These formats are continually being developed by the
IEC standardization committee, for which reason new and previously reserved bit com-
binations are added. The Dig Analyzer Protocol window can be upgraded to the latest
state with the aid of updates to the R&S
UPP software.
The values and meanings currently available for a bit field can be found in IEC stan-
dard 60958-3 (Consumer Applications) or IEC 60958-4 (Professional Applications), or
the Protocol Generator panel.
5.31.3 Error Flag Display
In addition to channel-status information, the "Dig Analyzer Protocol" window also dis-
plays the "Error-Flags " which indicate errors in the data stream. When an error occurs
the color of the "LED "changes from green to red. As soon as the error disappears the
"LED " goes back to green.
Just as with the channel-status information, the error flags are read at the end of a
measurement cycle. The error flag update rate therefore depends on the measurement
time of the function that has been set. In the case of single measurement the status
read at the end of the measurement stays unchanged until a new measurement has
started and finished.
