General Information/Problems


Quick Start:

-> Look up a frequency combination.

-> Check a frequency set.

-> Expand a frequency combination.

-> Create a frequency combination.

The Online Database

-> Frequency ALLOCATION.

The frequency ALLOCATION pages list the compatible frequency combinations in order of country and system. To retrieve a combination:

-> Hardware-Versions.

The hardware-versions, which are the raw material of the combiner, are found in the combiner's hardware version set chooser or on the desk top under 'Sets'. The hardware-version-sets of the WMS61 and WMS81 series are defined by the following symbols: The hardware sets of the WMS300 series are defined by slightly different symbols: To change the system of a harware-version-frequency set:

The Combiner Applet

-> Frequency COMBINATION.

The combiner extracts from a frequency set or a group of frequency sets a combination of frequencies with low mutual side band noise and low intermodulation distortion of the respective carriers. To find such a combination: Estimation of the worst case (no result) computing time: To speed up a combination of sets, we recommend a tedious but quite effective procedure: Another simple but not quite as efficient method of acceleration is:

-> How to copy/print results.

To copy results (for instance to your email-system) click the cursor into the result-window, and press ctrl-a and then ctrl-c. the results are placed in the systems clip-board.

Printing is not yet possible directly from the applet. Use the same procedure as above to copy the results, and paste them into your word processor software.

General Information/Problems

-> Browser problems.

The check-applet requires a java (>1.1) enabled browser. It has been successfully testet with: If the icons are not down loaded into the applet install a new browser.

-> How to down load the program.

If you want to use the applet offline, you have to down load it via the down load section. You need a unzip-utility to unpack the zip-archive, like winzip. Once down loaded, you extract the file into an empty directory. To start, look for the index.html file, and double click on it.
