Unit was reset to factory defaults, to exclude possibility that user attenuation data is loaded. Any combination of inputs and outputs (if internal RF gen is used) give same result, so it is not a frontend problem. Physics Astrophysics (astro-ph new, recent, search) Condensed Matter (cond-mat new, recent, search) General Relativity and Quantum Cosmology (gr-qc new. For my unit, running this once helped to pass the external loop tests. Get your torque with all the trimmings, in the most comfortable and exhilarating. It's somewhere in the starting menu (firmware manager). I am sort of new-ish to Michigan and this whole ORV sticker thing. Unless pictured, no power adapter / power cable included Photos are of the actual unit for sale. No additional items or accessories are included. Includes Radio Communication Tester as pictured. Cosmetically in good condition showing minor scuffs / scratches / blemishes from previous use. All self tests in maint mode shows similar difference (about 2-3 dB), both with internal and external loopback. Re: Rohde & Schwarz CMU200 repair (analyzer levels) There's an option to re-calculate all the compensation tables inside the unit, e.g. Tested working and is guaranteed functional. At start difference was about 4 dB, it slowly decreased and now 'stabilized' at about 2.3 dB 100 MHz after running continuously for a few days. All items are carefully packed, with brand new packaging materials.

But CMU analyzers (both spectrum analyzer and power vs time analyzer) show lower value. Description Rohde & Schwarz CMU200 Universal Radio Communication Tester Tested. Signals (both from external and internal RF generators), connected to any of CMU inputs correctly measured by wideband power meter in CMU (0.1-0.2 dB difference, comparable to expected losses in test cable). Unit have 2 RF generators, and both work fine, I can see right levels and frequencies on another (calibrated) spectrum analyzer. Most of problems was solved, a lot of black dust was cleaned from everywhere, alignments (Vref and reference frequency) was made, but now I come to a thing that I can't understand (at least at once). Hello, I currently trying to fix Rohde & Schwarz CMU200 purchased as a non-op unit from eBay.
