Working with Memory Traces
You can save the image of both traces to the memory of the R&S Spectrum Rider and
later restore it and compare it to a live trace. The memory trace is always colored white
to distinguish it from the live trace.
Measurement settings
Because the memory trace is just a bitmap, any modifications to measurement settings
like span or reference level are nor reflected in the memory trace.
When you save a data set, the R&S Spectrum Rider also stores the associated trace in
the trace memory. If you restore it at a later time, you can display the memory trace as
if it is a normal memory trace.
1. Press [TRACE] key.
2. Select the trace you want to store in the trace memory with the "Select Trace" soft-
key.
3. Select "Trace
▶
Memory" softkey.
The R&S Spectrum Rider saves the active trace.
4. Select "Show" softkey.
5. Select the "Enable Memory 1 " menu item.
The R&S Spectrum Rider shows the corresponding memory trace. If active, it
labels the "Memory <x>" menu item with an active radio button.
6.2.6.5
Using Trace Mathematics
Trace mathematics subtract the memory trace from the live trace and vice versa and
then display the results.
1. Press [TRACE] key.
2. Select "Trace
▶
Memory" softkey.
3. Select "Show" softkey.
4. Select "Trace Math" softkey.
5. Select the "Trace-Memory" or ""Memory-Trace"" menu item.
6. The R&S Spectrum Rider calculates and shows the resulting trace.
7. To turn off trace mathematics, select the "Off" menu item.
