3 Short-Range Comms & IoT Mode
3.10 Spurious Emissions Measurement
3.10.10.1 Select Trace
Specifies the selected trace, which is the trace that will be affected when you
change trace settings.
Select Trace appears above the menu panel, indicating that it applies to all controls
in the menu panel. Select Trace is blanked if you select a tab whose controls do not
depend on the selected trace (for example, Trace Function).
Notes The selected trace is remembered even when not in the Trace menu
Dependencies For the Swept SA measurement:
–
In Image Suppress mode, when you select a trace it becomes the active trace, and the formerly
active trace goes into View
–
When you turn on Image Suppress, Update turns off for all traces except the selected trace
For the ACP measurement, when Meas Method is RBW, FAST or FPOWer, Select Trace is disabled
Preset Trace 1
State Saved Yes
3.10.10.2 Trace Control
The controls on this tab allow you to set the "Trace Type" on page 1731 and its
update mode.
There are four Trace Types:
–
Clear/Write
–
Trace Average
–
Max Hold
–
Min Hold
Each type handles data in a different way.
Each trace also has two values that determine whether it is being written or not, and
whether it is being displayed or not. These values, Update and Display, are
described fully in the "View/Blank" on page 1736 control description. Essentially,
when Update is ON, a trace is updating, and when Update is OFF it is not. When
Display is ON, it is visible and when Display is OFF it is not. These terms are used
throughout the descriptions in this section.
