6.2.2.1 Select Trace
The real-time spectrum analyzer allows for up to three traces to be displayed at the same time. Each
trace has its own color (Trace A - Yellow, Trace B - Whtie, Trace C - Red). All traces can be set parameter
independently. As a default, analyzer will choose Trace A and set the type of the trace as Clear Write.
6.2.2.2 Trace Type
Set the type of the current trace or disable it. The system calculates the sampled data using a specific
operation method according to the trace type selected and displays the result. Trace types include Clear
Write, Max Hold, Min Hold, View, Average and Blank.
1. Clear Write
Erases any data previously stored in the selected trace, and display the data sampled in real-time of
each point on the trace.
2. Max Hold
Retain the maximum level for each point of the selected trace. Update the data if a new maximum level
is detected in successive sweeps.
3. Min Hold
Display the minimum value from multiple sweeps for each point of the trace and update the data if a
new minimum is generated in successive sweeps.
4. Blank
Disable the trace display and all measurements of this trace.
5. Average
Set the averages times of the selected trace. and set the average number of traces.
More averages can reduce the noise and the influence of other random signals; thus, highlighting the
stable signal characteristics. The larger the averages times is, the smoother the trace will be.
