I set my NanoVNA-H to sweep from 3.5 MHz to 3.6 MHz and then listened to the signals on a shortwave receiver.
I could hear a signal at 3.5 MHz and 3.6 MHz and possibly the sweep points in between. Harmonics were also heard with the 3rd harmonic much stronger than the second harmonic. The sweep appeared to repeat about 17 times every 5 seconds.
Is a square wave signal being sent out for each frequency in the sweep? What is the off time between each pulse?
This is really just for curiosity as I try to understand the operation of these very useful instruments.
Thanks, Kent
