1 Overview
During commissioning and maintenance of RF transmitter stations, various measurements have to be performed to ensure proper operation. To make the test results comparable between service teams or between maintenanceperiods, identical conditions and settings for the test equipment are necessary. Changes compared to earlier measurements are taken into account during maintenance, as these might possibly affect the operation of the transmitterin the future. All measurements need to be documented and archived for customer approval or later comparison. In order to save time and costs, the measurements areautomatically documented in a standardized test report. The R&S FSH3 provides tools for standardized test setups to enable easy and also customized test report generation. This application note describes the typical steps, beginning with predefined test setups, right through to the generation of a customized report (using the FSH View software and a Microsoft Word macro) involved in automatic reportgeneration. For commissioning and maintaining RF transmitter sites, the following steps are necessary for measurement setups and documentation:
-

Define test setups for different service teams Perform the measurements and store the results Prepare the test results for documentation Generate a test report for the specific transmitter site.

For each step, the R&S FSH3 provides the necessaryfunctions and tools to minimize the workload and to avoid errors. Version 5.0 or later for both the R&S FSH3 firmware and the FSH View software are required for the procedures described in this application note.

2 Definition of Test Setups
Generating the correct test setups is a prerequisite for performingmeasurements that are both straightforward and repeatable. This is particularly important if different individuals install or maintain transmitter sites. Different sites need to be tested in exactly the same way, both when installed, and during maintenancefor comparability both across site and onsite across time With the R&S FSH3 the specific test setups need be generated only once in the centrallaboratory of a service organization or by the client of a service provider, for example. The test setups are generated by setting the measurement parameter on the instrument, which stores the data set together with the test result in the internal memory. Each data set is assigned an expressive name with up to 15 characters corresponding to the measurement such as • • • • Tx Power, Antenna VSWR,...
