I blew my vna after connection to a cheap digital attenuator, current surge
blew out front end. Use only passive fixed attenuators now.

So S21 has been damaged when I was checking a LNA, i gapped it for 2
seconds and hooked the attenuator on the wrong side.
It is a H4, I was going to order a new one as needed pass through on most
things I use it for.
Anyone know how to fix, is there a diode or anything that blows when input
is to high?
