Thanks for the additional explanation. These screenshots are now understood.

The method of measuring magnitude frequency response using a linear frequency sweep in the signal generator along with peak hold in the spectrum analyzer has significant limitations. To achieve higher frequency resolution ...

Thank you very much for the bug report. We will fix it in the next software release.

There is almost no signal in the Oscilloscope, or maybe the signal level is too low, only 0.02% as indicated by the input peak level indicator in the upper right corner of the screen. Please check the connection and the input gain settings.

Yes, MI basically uses the same signal processing chain. However, there may be some differences in the detailed implementation, such as those in the following aspects:
(1) the cutoff frequencies of the bandpass filter and low pass filter. In MI, they are not fixed but based on the measured carrier ...

Thank you for your questions.

In the wow and flutter measurement of Multi-Instrument, a window function (e.g., Kaiser 8) is used only to determine the average frequency of the test signal in the frequency domain. It is not used in FM demodulation. Alternatively, the average frequency of the test ...

1. Generally, with the Peak-Hold method, the slower the frequency sweep, the smoother the measured frequency response. You can also smooth the curve by right-clicking the Spectrum Analyzer window and selecting [Spectrum Analyzer Processing] > "Smoothing via Moving Average". Please refer to Section 3 ...

It looks like that you used the preconfigured panel setting "FRswph" to perform the frequency response test. In this method, the signal generator sweeps from 20 to 22050 Hz linearly over 300 seconds. The spectrum analyzer is set to peak hold mode with an FFT size of1024. The following screenshot ...

12. Allow (even) more DDPs
I know you've jumped from 16 to 24 DDPs. Thanks 1000 times for that.
But what about 32 ?

14. Spectrum analyzer - Please add 180dB range to Spectrum analyzer

17. DDP for Sampling rate, FFT size, Number of points, Number of channels ...

MI 3.9.14 has added an "f1 Notch" option in [Spectrum Analyzer Processing] to define the bandwidth used for calculating the fundamental power, in accordance with the notch filtering method specified in the AES17-2015 standard for THD and THD+N measurements. If the fundamental exhibits a wide ...
