Anybody familiar with this unit. I picked up a surplus unit and I want to check the various LTE band performance. Going through the manuals has been painfully slow. Does anyone have any scripts/cheat sheets for the various test procedures for 4gLTE? I am also not sure what option keys I have and many of the options are onobtanium. R&S products and keys seem to have a short life cycle and the dump support very quickly for even relatively newish models. I got the answer "we dont have the software or firmware to generate the key options" Incredible excuse for such a high tech company! |

I doubt you will get much help for your CMW500. It is an evolved model, that started with the CMU200. There was the CRTU (very similar hardware and same DOS mode, more about it later on) and then the CMU300. The reason the CMU200/CRTU are popular as second hand devices, is because they feature a DOS based mode that includes a full spectrum analyser and signal generator. The spectrum analyser is quite good and precise. While the CMU200 has many more options in this DOS frontend software, the CRTU offers less functions (but does include the same spectrum analyser and signal generator) and instead includes a Windows 2000 partition with specialized test software. This is the problem with your CMW500: it is a device made to test LTE hardware and very specific about it. In case of the CRTU, you don't even find any manual for the Windows 2000 environment. Instead it includes Visual Studio with the required C++ libraries, so you can develop your own software! This is for for instance for a mobile phone factory to do automated quality control. So I wouldn't blame R&S for giving you that answer: you just happend to purchase a high tech device that is beyond its life span and no manufacturer will give you free support for it. And neither paid support, because you are expected to purchase the follow up device. Often these are not "purchased" but rented or leased. For you to get an idea: I once visited a customer that had a container outdoors (but within their company grounds), full with R&S Audio Analysers. I asked about them and was told they were to be scraped. So I asked if I could have one. I was told no, because there was a contract in place where every single unit had to be scarped with the respective paperwork confirming so. I was told (after asking why and thinking that each device would render around 1000 Euro on Ebay) that this was part of the purchase contract and, additionally, to prevent workers to steal components of the units in use for spare parts of the scraped ones. Another reason is to prevent competition to get hold of cheap equipment. There were further plausible reasons. Bottom line is: you have a great device, but perhaps a CMU200 would have been better as a hobbyist spectrum analyser and signal generator. All that said, there is a topic here (search for it) that has a R&S keygen script. I am pretty optimistic that it will work to generate the keys for the options of your device. Just remember that activating options for hardware that is not present will only slow down the boot process. You should only activate relevant software options and those you have the required hardware for. |

Rudi' s lab has a whole series on the cmu200 |

@tv84: I was hoping that the CRW500 wasn't too different from the CMU200/300 generation, in terms of license mechanism. I guess that makes the CRW500 even less atractive for hobby users... |
