Trace/Detector
2. The trace is updated in a series of discrete steps, with measurement data being gathered
between each step. This will be the case for slow sweeps, multi-chunk FFT’s, etc.
In the first case, no update indicator is required. In the second case, however, a visual indicator
exists on the trace where the new data is being written, a green “caret” or ^ symbol, which moves
across the bottom of the graticule showing the current trace point.
Trace Annunciator Panel
The trace annunciator panel appears on the right hand side of the Meas Bar. Here is an
explanation of the fields in this panel:
On the line labeled “TRACE”, each trace number is shown, in the trace color. A green box is drawn
around the currently selected trace
Below each trace number, on the line labeled “TYPE”, is a letter signifying the trace type for that
trace number, where
W=Clear Write
A=Trace Average
M=Max Hold
m=Min Hold
If the letter is white it means the trace is being updated (Update = On); if the letter is dimmed , it
means the trace is not being updated (Update = Off). A strikethrough (e.g., W) indicates that the
trace is blanked (Display = Off). Note that it is possible for a trace to be updating and blanked,
which is useful if the trace is a trace math component.
The third line, labeled “DET”, shows the detector type for each trace, or, if trace math is on for
that trace, it shows an “f” (for “math function”). It is not always possible to have a unique
