Thank you for the quick response. It might be called nit-picking, and I promise not to push this matter any more, but all other windows in REW do not have any problems with my low-noise floor. Among them are the humble Hann window with its first sidelobe at -31dB and Blackman-Harris 4 at -92dB...

I'm not using D-C 150 window in my work (I'm using Blackman-Harris 7 most of the time), but I ran across this peculiarity of the D-C150 and thought it worth mentioning. In addition to the signal amplitude, the Dolph-Chebyshev 150 window appears to be also dependent on the overlap fraction. The...

When testing a Topping D10b DAC at different output voltages in loopback with a Cosmos E1DA ADC I noticed that the spectral noise floor of the Dolph-Chebyshev 150 window varies with the signal amplitude. Both the noise level and its variance, i.e the line thickness, are affected. No other...

Splendid, thank you very much!

Thank you very much, it's perfect for my purposes.

Hello, I'm grateful for the possibility to analyse my noise measurements in terms of V/rtHz in REW. However, when I load more than one measurement stored in V/rtHz and then switch to "All SPL", they are displayed in terms of dBV. If I then want to calculate e.g. the sum of two noise levels I...

Thank you for the swift reaction!

Sorry, forgot the attachment...

Hello, When measuring noise I notice a disagreement between the noise levels displayed in the RTA upper right and Distortion panels. Referring to the attachment, I'm measuring thermal noise of a 50 ohm resistor, amplified by an LNA with a gain of 60dB and a flat noise floor at 0.39nV/rtHz RTI...
