But seriously, do you use an oscilloscope routinely for audio or is this one of those work related things? ;-)
"But seriously, do you use an oscilloscope routinely for audio or is this one of those work related things? ;-)"
Absolutely! I can't see what's going on otherwise. My bare eyes have a hard time directly seeing those sluggish photons. And since I'm retired what I do is usually audio related.
Yea, I've got most of the normal other stuff like THD analyzers and FFT via computer and various signal generators. The one thing I sorely would like to have is a > 1GHz spectrum analyzer but bench space and budget haven't been kind to that desire so far. (I do miss being able to drag stuff home from the office on weekends. But not much...)
Do you have an extra $1300 for a 1.5GHz entry model Spectrum Analyzer?
You're right; the price for spectrum analyzers begins around $1300 or so. However, you can get what looks like a very nice 50-MHz four channel digital storage oscilloscope for $399. I'm tempted to buy one even though I already own a Tektronix two channel digital storage oscilloscope that I paid about $1600 for twelve years ago. ;-)
"Do you have an extra $1300 for a 1.5GHz entry model Spectrum Analyzer? Rigol..."
Well, maybe not "extra" exactly but I could scrape it up. That do look interesting, have you any experience with their products and service? I'm a Tek fancier from long experience and loyalty to a local outfit but I could be bought... cheaply.
I have no direct experience but I've read reviews of Rigol gear including that Spectrum Analyzer in QST Magazine, as well as on YouTube.
I was a Tek fan for a long time too but it seems that in recent years a lot Tek instruments are just Tek spec'd but manufactured offshore. Nothing wrong with that I suppose but if you dig into the specs, like screen size and resolution, standard features, etc., other brands seem to offer more.
Agilent for example, or should I say Keysight Technologies since they changed their name last year. This used to be the old HP. Their scopes seem to offer more for less vs Tek.
With Rigol even though they're made offshore, they have good representation in the US for sales, service, and support. You might get even more for your money from brands like Owon but I wonder about US based service and support.
If you visit YouTube and search on EEVBlog you will find a long series of videos done by Engineer Dave Jones, many of them video reviews of test equipment and power supplies. If you search for EEVBlog Rigol, you'll find a bunch of Rigol gear that he's reviewed including Rigol spectrum analyzers, power supplies, and scopes.
Fun stuff, much of it I can't afford or justify as a hobbyist.
BTW, I find it interesting that Rigol's US Sales headquarters is located in Beaverton, OR. Tek used to be headquartered there, maybe they still are. I'm not sure.
