3.6.7 Using Markers
Use the "Marker" parameters to activate markers and to modify their position. The fol-
lowing "Marker" hotkeys are available at the bottom of the GUI:
Hotkey
Description
"Ref. Marker ..."
Enable or disable the reference marker, select a trace and the marker position on
that trace.
"Marker 1 /2 ..."
Enable or disable marker 1 or 2 and define the marker position (absolute or relative
to the reference marker).
Depending on the trace mode, a trace can also be selected.
"Select Trace Mode"
Define whether all markers are collectively set to the same trace or to individual
traces.

3.6.8 Common View Elements
Below the title bar, all views show the most important RF and analyzer settings as shown
below.

Tables
Most detailed views show tables providing a statistical evaluation of results measured in
a selected slot. For multislot measurements the "Scalar Slot" is used and displayed above
the table while for single slot measurements (e.g. "Emission Mask") the "Preselected Slot"
is used.
Modify the "Scalar Slot" to display the results of another slot. A restart of the measurement
is not required.
The statistical values in the tables are calculated as follows:
●
Current:
Value of the result obtained in the last measurement interval. For some
modulation results a current RMS value (the average over all samples in the mea-
sured slot except the guard period) and a current peak value (the peak of all samples
in the measured slot except the guard period) is available.
●
Average:
Average of all "Current" values referenced to the last statistics cycle.
●
Maximum:
Largest or smallest "Current" value that the R&S
CMW obtained since
the start of the measurement. For errors the Max result is the biggest absolute value
with the correct sign.
●
Std Dev:
Standard deviation of all "Current" values since the start of the measure-
ment.
All statistical results (statistical tables and "Average" or "Max" traces) are calculated
according to the general rules for statistical results.
