2.3.2 Trace
As the sweep signal is displayed as a trace on the screen, you can set parameters
about the trace using this key. The analyzer allows for up to four traces to be displayed
at one time, and 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).
2.3.2.1 Select Trace
Selects Trace 1, Trace 2 or Trace 3 in order to set parameters associated with each.
The default trace and type is Trace 1 and Clear Write.
2.3.2.2 Trace Type
Sets the type of the current trace or disables it. The system calculates the sample data
using a specific operation according to the selected type and displays the result. Trace
type contains Clear Write, Max Hold, Min Hold, Video Avg, Power Avg, Freeze and
Blank. Every type has its own parameter icon that is shown on the left of screen. Take
Trace 1 as an example and see the following icons.
1. Clear Write
Sets the trace data to the minimum and the value of each point is the data
acquired from the real-time sample.
2. Max Hold
Maintains the maximum for each point of the trace, and updates each trace point
if a new maximum is generated in successive sweeps.
3. Min Hold
Maintains the minimum for each point of the trace, and updates each trace point
if a new minimum is generated in successive sweeps.
