f) P/Frame, P/Slot Graph, P/Slot Table
The P/Frame, P/Slot Graph, and P/Slot Table test settings differ from the P/t Normal GMSK settings
(see p. 4.11 ff.) in several respects:
•
The measurement statistics is simplified; only the repetition mode can be set.
•
Everything related to the measurement curve (Display Mode, Markers, Display settings) is omitted.
•
In the P/Slot Table and P/Frame applications, the number of slots to be measured (Slot Count,
Frame Count) can be set.
The remaining settings are identical with those of the P/t Normal GMSK application; see page 4.11 ff.
Note: No Free Run trigger must be used in the P/t Multislot, P/Frame, P/Slot Graph, and P/Slot
Table applications.
Measurement Results
The measurement results depend on the application selected.
a) P/t Normal GMSK
The values shown in the measurement menu Power , application P/t Normal GMSK, can be divided into
three groups:
•
Settings
•
Scalar measurement results (single values)
•
Arrays (the measurement curve plotted as a function of time)
These values are indicated in two parameter lines, the test diagram and an info box:
