I don't know the HackRF product, but the SDRPlay, with several possible 
freeware control programs, is a very capable product for chasing RFI. So 
are DSP transceivers, like those made by Flex and Anan. This slide deck 
for a talk I've done at Pacificon, Visalia, and to several ham clubs 
includes several suitable SDRs that would work fine. When I prepared 
that talk I found a very nice website that listed more than a dozen SDR 
receivers, ranging in cost from about $25 to more than $500.

I've never heard of "frequency tuned zero span analysis."  Do you mean 
listen to audio at a single RX frequency and display the audio spectrum? 
That would be a software function. Some poking on the internet (or even 
asking around among SDR users) would likely find control software that 
does that.

Here's a great starting place. https://www.dit-dit-dit.com/
