user interface
in addition to the menu items file, edit, window and help common for windows applications, the emi software r&s es-k1 can be controlled via two additional menus.
in the options/device configuration menu, the user needs to define the device configuration only once, i.e. test receiver and accessories. the language, e.g. german or english, can also be selected.the test menu is provided for interactive adjustment and control of the individual devices. the automatic test sequences which are script-defined (see opposite page) are started in this menu. in addition, a variety of test and analysis functions is available.
the file menu provides import and export functions for exchanging data within a user group. furthermore, the complete software configuration can be stored.
in addition to the scan, sweep and measurement functions, scripts - test sequences in a macro language - allow fully automatic or interactive control as required. a set of user-defined script parameters controls the test sequence and the generation of reports. beside the standard scripts, user-specific scripts can be generated and existing scripts modified with the aid of the r&s es-k2 option, thus allowing each user to integrate specific know-how into the measurement in an optimum manner. effective debug and further test facilities are also available.
as a linking element between the scan or sweep function for preview of the spectrum on one hand and measurement at discrete frequencies on the other, emi software r&s es-k1 offers a wide selection of data reduction methods. the most important evaluation methods are:
- acceptance analysis, subrange maximum and minimum determination
- peak and maximum analysis
- narrowband/broadband discrimination using tuning and peak/average comparison methods
furthermore it is possible to combine test results, read out broadband interference to mil in a display (/1 mhz) or suppress known environmental interference by means of a frequency list, e.g. for measurements in open-field sites.
emi measurements require the generation and processing of a large variety of data: transducer factors, limit lines, scan and sweep data as well as results in graphic and tabular form and test reports for documentation. a database for data management is integrated into emi software r&s es-k1. this enables convenient data access by means of concise short descriptions, thus doing away with cumbersome file searching.special input masks, e.g. for generating transducer factors and limit lines, can be used for extending the data records supplied. major standards are covered by factory-ready scripts to allow fast and easy use of emi software r&s es-k1.
versatile and flexible display of results is possible in tabular or graphic form. a maximum of eight test results, limit lines and transducer factors can be displayed simultaneously - even in different windows - with linear or logarithmic scaling of the frequency axis. the shape, line type and colour of the traces can be adapted optimally to requirements. there are two mouse-controlled markers for interactive graphic evaluation. the zoom function allows enlargement of the result display to any size.
the integrated report configuration function allows the user to customize the format of a test report to a large extent. in addition to the report header, all data relevant to the measurement can be output, e.g. scan and sweep tables. test results, limit lines and transducer factors can be output in tabular and graphic form.when generating reports, users can also view the log file prior to printing by means of print review. in addition, graphics and tables as well as rtf (rich text format) files can be saved. users can also take advantage of the customization feature with which a familiar word processing program (e.g. word for windows) can be used to insert graphics, tables, or measurement result lists wherever appropriate.the report can be output on any printer supported by windows.
emi software r&s es-k1 supports all emi test receivers and spectrum analyzers from rohde&schwarz: the test receiver family r&s eshs, r&s esvs, r&s espc, r&s escs and r&s ess, the spectrumanalyzer-based emi test receivers r&s esai, r&s esbi and r&s esmi (up to 26.5 ghz), as well as the r&s esib7, r&s esib26 and r&s esib40 (up to 40 ghz) and the test receivers r&s espi3, r&s espi7 and r&s esci.
various drivers are available for accessories such as:
- mast and turntable system for the measurement of rfi field strength
- artificial mains networks and absorbing clamps/slideways for the measurement of conducted emissions
- matrix for switching antennas and transducers
