I was also able to find the basic datasheet but its kind of vague about how usefull this is for anything else than cellular 2G/3G stuff. A proper manual would be great.
For a lot of R&S kit getting manuals and software require an service account (GLORIS) with R&S unfortunately.
Based on this http://www.helmut-singer.de/stock/-1871243771.html I am hopefully getting a RF signal generator and somehow usable spectrum analyzer.
Typical HS, they're asking 10 EUR grand for it. I do wonder who actually pays their insane prices. Madness.
But hey, you could ask them if they buy yours for EUR8k. Must be a bargain for them
Wuerstchenhund: Thats what I questimated based on the info that CRMU is somewhat newer version of the CMU200.
Well, it isn't, really. Both CMU200 and CRTU were made for different purposes. The CMU200 was designed as an universal comms tester for various cell phone standards (GSM, CDMA, W-CDMA, UMTS/HSDPA, EV-DO) as well as Bluetooth, for both lab and production use, and also with general (non cell phone testing) applications in mind.
The CRTU on the other hand was designed as an automated test platform for cell phone production. While the CMU200 could be used for the same task, automated testing with the CMU200 requires an external computer as test controller. The CRTU doesn't as it comes with a built-in Windows2000 PC. On the other side, the CRTU is very limited in its capabilities, and doesn't support everything the CMU200 does.
There are various variants of the CRTU. In general, the -PU are the Protocol Analyzers (focussing on the logical level) and the -RU are the Radio Controllers (dealing with the RF part). The chassis is essentially the same as the CMU200 chassis, with the exception of the righthand front where the CMU200 has some Sub-D connectors and a speaker while the CRTU has three N connectors for the built-in power divider. There also are some differences on the rear connector panel.
The fact that the CRTU was primarily designed for automated cell phone testing shows in several areas (i.e. the CRTU can only act as a Base Station while the CMU can act as Base Station and as terminal/receiver). Also, for the CMU200, most optional functionality is enabled when the required hardware module is installed, while the CRTU requires additional software licenses. I'm not sure if this also affects the Basic Functionality (Spec An, RF generator etc), or if this functionality is even available in the CRTU. But I do know that the CRTU only supports a subset of functionality of the CMU200.
The original CMU200 (with FMR5 controller with AMD K5 processor and with PS/2 keyboard interface) was introduced in 1999 and the CRTU in 2002. Both were supported until around 2010 when they were replaced by the current CMW500.
Feel free to make a reasonable offer after I fiqure out what options(if any) I have got in my units.
Sure. Send me a PM over the forum when you get the units.
