Overview - Remote Control - Measurement Control

The CMU offers a variety of measurements which are arranged in function groups and measurement groups. All measurements are controlled according to the same basic concepts. The benefit of this structure lies in the close analogy of all function groups. Commands belonging to different measurements have the same structure and syntax.

The following sections are devoted to the principles of measurement control:

• A measurement group can be split up into different subgroups by means of applications (optional, i.e. not available for every measurement group).
• Four different measurement states are defined; they can be accessed with a set of measurement control commands.
• The end of the measurement (or of a particular measurement stage) can be indicated by means of the event reporting system.
• Statistical settings comprising the repetition mode, statistic count (optional), stop condition (optional), and display mode (optional) control how the measurement is performed. The possible measurement states depend on the repetition mode.
• For many measurements it is possible to specify limits and perform a limit check.
• The current status and the results of the measurement can be queried in a systematic way.

Some measurements do not require the full scheme. E.g., the function group RF Non Signalling described in this help system uses none of the features characterized as optional in the above enumeration. Examples for these features can be found in the operating manuals for digital network tests, e.g., GSMxxx-MS.
