3.8 SEM Measurement
3.8.20.2 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.
Trace Type
There are four trace Types:
Option Parameter SCPI Example Details
Clear/Write
WRITe :TRAC2:TYPE WRIT
See: "Clear/Write" on page 1199
Trace Average
AVERage :TRAC2:TYPE AVER
See: "Trace Average" on page 1200
Maximum Hold
MAXHold :TRAC3:TYPE MAXH
See: "Max Hold" on page 1200
Minimum Hold
MINHold :TRAC5:TYPE MINH
See: "Min Hold" on page 1201
Full descriptions of each type are provided below. You may select one of these types
for each trace. Re-selecting the current Trace Type initiates the same action that
selecting it the first time did, even though it is already selected. For example,
selecting Clear/Write while Clear/Write is already selected will nonetheless clear
the trace and begin rewriting it.
Besides the Trace Type, the "View/Blank" on page 1736 state must be set to Active
(Update: ON, Display: ON) for a trace to be updating and visible. Selecting any Trace
Type automatically makes the trace Active.
