Really interesting to watch. I spent €1000 on a faulty E4433B (which I had to repair). This would have done most of what I wanted. Always good to see these old "money is no object" industry beasts kept alive for other purposes.
Thanks! Yes, in a way, the CMU can be quite a bargain if you find a good working specimen, and may be more interesting than some dedicated-task devices that remain expensive over time...
Thanks Rudy for the video. While looking at the frequency range of the secondary ( or Aux) generator chanel, I noticed that I wasn't able to go above 1100MHz rather than 1220 MHz has shown. I have B-95 option. I don't know if this is related to my CMU.
Thanks for the reply! I think you are right. In the CMU200 Operation Manual (2010, FW5.20) (1100.4903.12-06) on page 6.53 I read “350 MHz to 550 MHz | 700 MHz to 1100 MHz | 1400 MHz to 2200 MHz” as supported frequency ranges by the CMU-B95. My 1220 MHz may have been a mistake... Looking at the same page in that manual, it also seems that AUX TX2 (in CMU-B96) does support the 350 MHz to 550 MHz band, only the two higher ranges. Would make sense, as AUX TX2 was originally envisioned to modulate a UMTS signal to test non-blind handovers from GSM to UMTS, and UMTS does not support the 450MHz band (en.wikipedia.org/wiki/UMTS_frequency_bands). But I do not have the CMU-B96 option, so I cannot test that.
@@rudiselectronicslab861 Thanks Rudy for the feedback. While I was looking at Aux Tx on RF2 ouput, I noticed a "strong" signal leakage from Tx placed in RF3 output set at 2.7GHz 0dBm. The leakage signal power was at -50dBm, which is strong versus the Aux Tx power at -60dBm. Moving Aux Tx to RF1 improves the situation, but it does not solve completely the problem. Is this something you observe?
Thanks again Rudy. I am very happy with these videos about the cmu200 because I am the proud owner of this device.
Great to hear!

Здравствуйте! Подскажите, можно ли этим прибором работать в низкочастотных диапазонах от 1.8 до 30 МГц? Есть ли функция однополюсного ssb режима?!
