evaluation interests. It is assumed that users with similar interests are grouped together in a User Group. R&S ARGUS stipulates that users wishing to measure with the definition files of another user or evaluate the data of another user must belong to the same user group as the other user. A set of data which is to be evaluated must be comparable. R&S ARGUS requires that any set of data which is to be evaluated must come from the selected Measurement Units. User Groups are the current owners of R&S ARGUS files. These user-selectable, user group names are assigned to each user. All files are stored with the user group name of the user.
Measurement modes All measurement tasks being run by the measurement software can share the same hardware, i.e. measurement devices and accessories. Naturally, the hardware can be available to one task for a certain time only. Nevertheless, thanks to sophisticated task scheduling within the software, the different measurement modes are able to consecutively use the hardware resources according to the time and priorities the operator has set for each. As long as the number and duration of the tasks are within reasonable bounds, it is easy to arrange for several measurement modes to use the same hardware. All this is available under a single license with R&S ARGUS running on the system process controller.

A second mouse click, on a device icon, opens the interface from which the user can control the device and perform the measurements. This interface simulates the functions and the settings of the device. Depending on the device driver, it contains several tabs each corresponding to a measurement type which can be performed by the device in question. Depending of the measurement type, the measurement results are shown using different types of graphics, tables or a numerical display. The mea-

The Spectrum mode gives the user a quick overview (level) of a frequency spectrum. This can be performed with scan (scanning from start frequency to stop frequency using frequency increments), frequency list scan (scanning using frequencies from a frequency list) or transmitter list scan (scanning using frequencies from a transmitter list). Additional measurements (e.g. the frequency offset or modulation) on all signals within the frequency band can also be made if the receiver has Monitoring Software R&S ARGUS

In the Antenna Analysis mode, level measurements are performed on one frequency while the azimuth, the elevation or the height of a directional antenna is varied. This mode is only activated for steerable antennas. The user can define the antenna settings in two ways: he can select a range for the antenna and the antenna covers this range using the selected step width or he can select a settings list. In this list, he can enter antenna settings.

The measurement results are displayed using a yt plot (measurement value vs. time). The measurement results can be saved for further evaluation or printing out. A report can be printed directly from the IMM.

Number of originating frequencies = 3: B and C combinations are calculated from the list of possible originating frequencies. A is calculated from the formulas and then a check is made to determine if this frequency ( IF bandwidth / 2) is in the list of possible originating frequencies.
In the final step, the intermodulation products calculated in this way can now be investigated by clicking the Start button in the IMM dialog window. All frequencies which can theoretically cause the intermodulation are compared acoustically with the observed intermodulation, using the receiver’s builtin demodulator.
The results are stored in an IMA Result file, sorted in the order of decreasing probability. The most probable results are those with the fewest original frequencies and the lowest order. The calculation results can be saved to an IMA Result file and reloaded at a later date.

The Detection of Unknown Frequencies mode provides a very efficient way to automatically identify new, unknown transmitters. In a first step a freely definable frequency range is scanned. Then, ARGUS will determine on which frequencies there is an emission. This can be done fully automatically (mathematically speaking, ARGUS will calculate local maxima in the spectrum). Additionally, the criterion for distinguishing noise from transmitters can be a user defined threshold or limit line. For fine tuning, e.g. to select weak signals from strong noise, a level offset can be applied. The result will be a list of occupied frequencies. In order to easily identify new, unknown emissions a list of known or licensed transmitters can be selected. These frequencies will not be included in the final list. Thus, the final result will be a list of occupied frequencies which are not known or licensed. This list can be saved for further evaluation and identification. Almost 40 transmitters have been automatically detected (see lower graphic), but after applying a reference list (e.g. imported from a license database) only 2 frequencies remain “unknown”

The alarm conditions and actions for a measurement parameter can be defined. A limit can be defined by a limit value (limit value is constant over the frequency range), by a limit line (limit values vary over the frequency range) or by the limit values from the transmitter list. The alarm actions can be a message, a signal tone or a measurement.

Subsequently, characteristic parameters like pulse duration, pulse repetition rate, scan cycle or beam width are determined for the signals found in step one. Again, the device settings are based on the internal knowledge data base.

If additional data is transmitted, it will also be displayed. This can be simple text messages or even multimedia content like graphics or slide shows.
Of course, it is possible to simply listen to the radio program via the PC speakers. Hardware requirements are receivers with LAN interface, e.g. ESMB (with HF-option); EB200 or EM050 / EM550 and for the PC a soundcard with speaker / headphones.

The Device Control Interface (DCI) is an open interface on device level. It enables the customer to create device driver for his own (even non-R&S) equipment. Via the DCI interface virtually all types of radio monitoring hardware can be integrated into the R&S ARGUS system. These devices can fully benefit from all features provided by R&S ARGUS, like e.g. measurement modes, evaluation, graphical display, file management … The content of delivery comprises detailed documentation, example source code and up to 5 hours online support. The software option DCI is available in two versions, Basic and Enhanced. Basic enables the control of devices like switch units, rotors, recorder, whereas Enhanced can control more sophisticated devices, e.g. receiver, analyzer, direction finder.
The Web Interface (WEB) enables access to ARGUS stations via a web browser. On the control PC only a web browser and the Java runtime environment need to be installed, no ARGUS specific software is required. Via this web interface receivers of the Rohde & Schwarz ESMB family, the ESMD, EM510, EM550, EM100, PR100 as well as the DDF255, DDF0xE and DDDF1xx direction finders and the UMS100/120 can be controlled. In addition, steerable antennas can also be controlled.
