3.9 Occupied BW Measurement
In this menu, Peak Search works as above. Peak Search all Traces finds the highest
peak in the Waterfall window. Add Marker Here takes the lowest numbered Marker
that is currently Off and turns it On as a Normal marker in the Waterfall window at
the point where you right-clicked (or touched-and-held). Move Marker n Here
moves the currently selected Marker to the point in the Waterfall window where you
right-clicked (or touched-and-held).
Trace Update Indicator
Trace updates can take one of two forms:
1.
The trace is updated in a single operation that affects all of the points in the trace
at once. This happens, for example, in the case of very fast (< 200 ms) sweeps,
single-chunk FFT’s, and the initial math operation after a math function is set for
a trace
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
FFTs, gated sweeps, 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. The indicator
is a green caret (^) , which moves across the bottom of the graticule showing the
current trace point.
Trace Annunciator Panel
This panel appears on the right hand side of the Meas Bar. Here is an explanation of
the fields in this panel, as shown below:
