Icons in the channel bar
The yellow star icon on the tab label (sometimes referred to as a "dirty flag")
indicates that invalid or inconsistent data is displayed, that is: the trace no longer
matches the displayed instrument settings. Thiscan happen, for example, when
you change the measurement bandwidth, but the displayed trace is still based on
the old bandwidth. As soon as a new measurement is performed or the display is
updated, the icon disappears.
The icon indicates that an error or warning is available for that measurement
channel. This is particularly useful if the MultiView tab is displayed.
The icon indicates that the results for the channel no longer match the data cur-
rently in the capture buffer. For applications using a long capture buffer, this icon
appears if you switch channels. The "IQ" disappears after you refresh the results
in the outdated application.
The icon indicates the currently active channel during an automatic measure-
ment sequence (
