Enjoyed the video - I wouldn't say it was really a teardown, lol.

The various measurements and setup were nice to see though and they transfer over to many other spectrum analyzers.

Nice, but a shame that we didn't get to see the analyzer front end. Were you worried about upsetting the calibration?
Should you find yourself in a chronically leaking boat, energy devoted to changing vessels is likely to be more productive than energy devoted to patching leaks.

Hi, sorry about that. I have been really stressed for time with a million ideas for new videos! So I have to rush a few things here and there. I thought focusing on experiments in this review would be more valuable.

Yes, these are all the basic measurements you would want to do. Too bad it doesn't have a digital down-conversion stage.

I don't think that it would have a strong impact on the calibration either way... Once I get some more time, I'll take it apart more.

I wonder if a DSA832 can be upgraded into a DSA875... ^-^

99.999% (with a margin of 0.001% error) not possible.  :scared:

Kind of a bummer not to see a real "teardown" on this one (likewise the Signal Hound unit from your other video.)  :-\  Glad to hear you're planning a follow-up.

Also, was that IEC power connector just a piece of plastic with contacts embedded in it, or was there a proper line filter?  If the former, all that nice shielding beneath the back cover was a complete waste of time/money on Rigol's part.

Unfortunately no filter as far as I can remember.
