3.8 SEM Measurement
Image Protection
Lets you turn IF Protection on or off. This is a technique used in unpreselected
instruments (such as Keysight’s modular instruments) to detect and suppress
images and spurs that may be present in non-preselected hardware.
IF Protection takes two sweeps and by correlating the data between them, provides
a single, correct power-versus-frequency trace.

3.8.20 Trace
Lets you control the acquisition, display, storage, detection and manipulation of
trace data for the available traces. The Trace Control tab of this menu contains
radio-button selections for the trace type (Clear/Write, Trace Average, Max Hold,
Min Hold) and View/Blank setting for the selected trace.
3.8.20.1 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
