measured trace instead of the real max hold or min hold trace.
A memory trace is complex by definition. Therefore, Data --> Mem stores the last measured trace instead
of the real max hold or min hold trace.
Remote control:
CALCulate<Chn>:PHOLd MAX | OFF
Restart Hold, Restart Hold All
Restart Hold restarts the max hold (peak hold) function for the active trace, discarding the old maximum
measurement results. This softkey is available only if Max Hold On or Min Hold On is enabled for the
active trace.
Restart Hold All restarts the max hold (peak hold) or min hold function for all traces in the active setup with
active max hold or min hold function. This softkey is available if Max Hold On or Min Hold On is enabled
for at least one trace in the active setup.

Marker
The functions in the Marker menu are used to position markers on a trace, configure their properties and
select the format of the numerical readout.
Markers
Markers are tools for selecting points on the trace and for numerical readout of measured data. A marker
is displayed with a symbol (a triangle, a crossbar or a line) on the trace, which may be a data trace or a
memory trace. At the same time, the coordinates are displayed in a marker info field or in a table. Each
marker can be defined as a normal marker, reference marker, delta marker or discrete marker.
Marker types
 A (normal) marker (M 1, M 2, ...) determines the coordinates of a measurement point on the trace.
Up to 10 different normal markers can be assigned to a trace.
 A reference marker (Ref) defines the reference value for all delta markers.
 A delta marker (Δ) indicates the coordinates relative to the reference marker.
 The stimulus value of a discrete marker always coincides with a sweep point.
A special set of markers M 1 to M 4 is provided for bandfilter search mode.
The most common tasks to be performed with markers can be achieved using the Marker menu functions:
 Determine the coordinates of a measurement point on the trace. In polar diagrams where no x-
axis is displayed, markers can be used to retrieve the stimulus value of specific points.
 Determine the difference between two trace points or the relative measurement result (Delta
Mode).
 Convert a complex measurement result into other formats.
Markers also play an important role in performing the following advanced tasks:
