I fail to see the need to worry if the active devices is connected across
a 50 ohm resistor. 50 ohms is effectively a short circuit as far as static
is concerned.
Here¡¯s a video from dave Jones of EEVBLOG measuring the DC resistance of
antistatic mats.
Two DVM probes are put next to each other, the meter, which can read upto
300 M ohm can measure anything.
I should have said that the meter can not measure the resistance - it is
over 300 M ohm.
You are not going to zap the NanoVNA with static on its RF input terminals.
