There are two peaks on the spectrum of HB100. What is the frequency with the smaller amplitude?

Thread Summary

The user observed an unexpected secondary peak next to the primary peak when running the phaser_find_hb100.py program. The final answer suggests viewing the frequencies in the phaser_gui.py FFT display to better understand the issue. No specific Analog Devices products or model numbers were mentioned.

Hi

When I ran the program phaser_find_hb100.py, I noticed something different from the official image. I expected a single primary peak, but strangely, I found a secondary peak next to the primary. From the image, it's clear that the power of the secondary peak is quite high. I'm not sure why this is happening, and I'm eager to hear from ADI engineers like Jon Kraft.

  

Thanks
