Trace/P/F
The sweep signal is displayed as a trace on the screen. In addition, DSA800
provides the Pass/Fail (P/F) test function. Trace/P/F is used to set parameters
related to the trace and P/F test.
Select Trace
DSA800 allows for up to four traces to be displayed at the same time. Each trace
has its own color (Trace 1 - yellow, Trace 2 - purple, Trace 3 - light blue and Trace
4 - green). All traces can be set freely except Trace 4 (a math operation trace that
can only be obtained using the other three traces).
Select Trace 1, Trace 2 or Trace 3 to set the corresponding parameters. By default,
Trace 1 is selected and turned on. The default trace type is Clear Write.
Note: The trace currently displayed on the screen can be stored in the internal or
external memory of the analyzer and can be recalled when needed. Press
Storage to save the trace according to the method introduced in “Storage”.
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, Video Avg,
Power Avg and Freeze. The corresponding icon of the trace type will be displayed
in the status bar at the left of the screen. Take Trace 1 (yellow) as an example and
the icons are as shown in the figure below.
