An EEprom test is provided for all modules.
Driver Init Test
The R&S CMW500 checks whether the operating system has properly initialized the
hardware driver for a specific board.
If driver initalization failed, or if the board is defective, the "Driver Init Test" is the only
board test shown. The test status is "failed". Contact your Rohde & Schwarz service
representative for assistance.
Temperature Test
The R&S CMW500 measures the temperature at different test points on a board and
compares the measured "Value" to the "Max" temperature limit.
●
A value below the "Max" limit means that the board operates under acceptable tem-
perature conditions. The board test is passed.
●
A value below the "Max" limit causes a failed temperature test.
Detailed Test
Detailed tests are board-specific tests that cannot be grouped into one of the previous
categories. In general, detailed tests are intended to be performed by R&S service rep-
resentatives.

Unit Tests
A unit test verifies that the communication between several internal modules of the
instrument is uninterrupted. A passed unit test usually proves that several modules (e.g.
boards and bus systems connecting these boards) work properly.
Unit tests and board tests
A unit test represents an efficient method for testing the instrument's overall functioning.
After a failed unit test, you can use one of the module tests to pin down the source of the
malfunction. Some examples of unit tests are described below.
