A very useful use of the TinySA is to track down sources of interference.

The horrors of today's unfiltered unscreened (and often unsafe - we had one leave burn marks all up our lounge wall after it exploded) chinese switched mode regulators/supplies, they have literally destroyed today's HF (and now slowly moving up into VHF/UHF) communications for many people around the globe :(

This is just one example - a baofeng walkie-talkie charger.

Don't forget to check PC supplies, The worst I found was a PICO supply.?

I've already used mine for tracking power line noise t 300mhz using a
small yagi for that band.

With an untuned amplified .3M untuned HF loop I"ve tracked all sorts
of items emitting significant noise.

Very handy.

You can measure the field strength of a source in dBuV/m if you change display units to dBuV and use a transducer calibrated in dB/m.? At a single frequency you can enter the tranducer factor (plus pre-amplifier gain if used) in Level->External Amp for a direct reading of field strength (only accurate at 1mtr distance from the source).

Similar technique using a current probe can be made for dBuA measurements.
