This latest firmware version with reduced DAC sample rate is stable on my H4.
- I ran it on a short connector for 20 minutes with no error drift over time in the display.
- I was able to successfully calibrate the H4 (using 201 sweep points Woo! Hoo!).
- The displayed plots match previous plots for known DUTs.
- NanoVNASaver no longer reports data out of range errors.
As an aside, there is no harmonic anomaly around 300MHz. Plots are clean with the unchanged threshold setting of 300MHz on tight sweeps of 295-305MHz, 299-301MHz, and 299.99-300.01MHz.
Thank you!
