Thanks to my job, I’ve never had any reason to buy test equipment.
All QRP rigs I’ve ever built were aligned using top-grade gear that I could never hope to afford so my only gear here in the shack is a Fluke 87 and an antenna analyzer.
But there have been many times I’d rather be able to work beyond the basic DVM tasks from here in the shack.
I first learned about USB-driven DSO’s (Digital Storage Oscilloscope) about 7 years ago. At that time, they were very basic…crude, even – and not very useful for signals above 5 MHz unless you were willing to pay an astronomical price.
Things have changed since then and these incredibly useful pieces of test gear are now at the point of both quality and price that makes them useful to the occassional QRP builder/tinkerer like me.
Reviews on ham sites and elsewhere are universally positive for the DSO-2250 so one is now on the way to this QTH.
When it arrives I plan to put it up against a more expensive scope at work and see how it compares on a variety of RF signals generated within my KX1 and other sources.
Screenshots of each – as well as other info derived from the comparisons - will be posted here.
