I will get a NanoVNA as it seems very useful. Just one doubt: where can I see the limits of the signal we can inject in TP103? Don't we need an attenuator in the nano-VNA to protect the radio circuit?

Here is my H4 hooked up with CH0 connected to TP103 and TP102 and CH1 connected to TP104 and TP105 per the manual.? SMA-M/BNC-F adapters and BNC-M to alligator clips.? One can do rather better with a custom cable set at the radio end.
I didn't make any effort to set the nanoVNA properly with a thru cal, etc.? It should be done for alignment, but not needed for just a demo.
