Ex- cept for the model number, only the name has changed from Satellite Finder to Sa- tellite Meter. However, when we started using it, it beca- me obvious that the changes are not only cosmetic. The look and feel of S30 is practically the same as its predecessor‘s – what is a good thing because nothing has been lost in its ease of use and sharp learning cur- ve the first user experien- ces. S30 has a very clear 128x64 backlit LCD and se- ven buttons. There are three connectors for the antenna cable, USB cable and a po- wer supply unit. Speaking DEVISER S30 Highly accurate handheld meter optimized for the satellite dish installer of which, in the set we get not only a plug type pow- er supply working from 100 through 240 V 50/60Hz but also a car charger. The plas- tic enclosure is protected with a blue rubber envelope but that is not all concerning ergonomics. Additionally, the happy owner of a S30 gets a vanity case attachable to a belt and a strip to hang the meter on a neck. If there is an USB connec- tor, one should expect an USB cable and some PC soft-

Adding a new transponder to ASTRA 2B channel plan (28.2 East) and signal started to drop. If this is more practical for you, you can even not pay too much attention to the re- adout but listen to the beep the S30 generates. The hig- her the pitch, the better the antenna alignment. We want to praise Deviser for the very fast response. It reacts im- mediately for even the smal- lest movement of a dish. Our S30 test sample had 16 popular European satel- lites per-programmed. If the transponder selection for a given satellite does not suit your needs, you enter the Main Menu (button MENU) and navigate to Setup - Sa- tellite Settings where you can adjust all parameters of any transponder associ- ated with the satellite. It is normal that not all satellite beams cover the whole con- tinent, so even if you live in Europe and you bought the S30 here, it can happen that some of the pre-program- med transponders are not receivable in your region. Editing parameters is easy as everything else in S30. If you put a little more ef- fort and install the SatePlan software on your PC (Win- dows OS), the edition will be even easier. Additionally, you will be able to add new satellites, new transpon- ders, enable some of them or disable others. The editor software is much more con- venient than the one we re- member from S20. It is here were we noticed the impor- tant differences between the new S30 and its predeccesor S20. Very important: the S30 can measure DVB-S2 transponders, something what its older brother S20 could not do. In this class of meters, the spectrum view is often just a gadget of little use. But not with the S30. Once you display a spectrum view, you can set a marker on a trans- ponder “mountain”, press the Enter button and the S30 will automatically reco- gnize all its parameters (fre- quency, SR, DVB type, FEC) and display its measurement results. It was really a very nice surprise for us to disco- ver this. In this way you do not even have to care about checking satellite charts. This is another new feature in S30. We were also pleased to find the DiSEqC 1.0 and 1.1 submenu. Using it, you can send a command to switch to a given signal source. We tested it with a DiSEqC 1.1 switch in our test antenna setup and everything was working as expected. Thanks to this function, you can not only verify that the antenna is aligned correctly but also that the whole distribution system is OK. After checking the func- tions and features, the time came to compare the Devi- ser S30 to another meter and see if its measurement results are really credible. We selected a very good and very expensive signal ana- lyzer as our reference. Ta- bles below show the results for two satellites: ASTRA on 28.2° East and EUROBIRD on ware, right? Right! You get all of them in the set. The software is provided on a small CD-ROM. Deviser also provides an Operation Manu- al in hard copy. The manual is very easy to follow and its electronic version is additi- onally available on the CD- ROM. The final items in the set are two female-to-fema- le F connectors. You screw in one of them to the S30. The other one is a spare you can use when the first one if torn off due to frequent usage. The small keyboard is self explanatory. You have 4 ar- row buttons and a power/ enter button in the middle. Below them, there are two buttons for entering the menu and leaving it. If you need to change settings, you simply highlight it and the use up/down buttons to change a digit. Some non- numerical settings, like sa- tellite names, can be edited on a PC and later downloa- ded to S30 thanks to the SatePlan Editor software for Windows. When you power up the S30 for the first time you‘ll truly enjoy its display. It is very easy to read thanks to the backlit. The meter starts with its signal finding window in which you can directly se- lect the desired satellite and its transponder. Except for the signal strength and qua- lity bars, the Deviser S30 shows the maximum values registered so it is very easy to see that we had turned our dish a little bit too much

Such small dif- ference is in fact a good re- sult. So far, we never found two meters showing exactly the same values. Usually, the difference was even gre- ater than that between the S30 and our reference. So, we confirm that the Deviser S30 results are credible. Because the test results were so good, we could not resist to check if the S30 could match our expensive analyzer with a very, very weak signal of low symbol rate. We selected the EU- ROBIRD transponder 11389 H SR=3642. Our reference meter measured the power as 62.2 dBµV and the MER as 3.8 dB. Practically it was a reception at threshold. The Deviser S30 was able to measure the power (56.3 dBuV) but could not to lock to the signal and measu- re its MER. It is not a sha- me for this class of a meter. We would be extremely sur- prised if it could match our reference. If you are thinking about buying a satellite meter, you should ask yourself: shall I really be forced to measu- re such weak signals? Usu- ally, there are much stron- ger transponders receivable next to weak ones - like in the case of EUROBIRD. And you can perfectly align the dish using rather the strong transponders than the weak ones. To sum it up, we can truly recommend Deviser S30 to all but extremely demanding professionals dealing with complex problems in satelli-
