Is your old scope getting a bit long in the tooth? Can't quite keep up with all the megahertz around these days? Our sponsor, Tektronix, is running a trade-in promotion till the end of the year. Whether it's an old
Tek scope you want to say your farewells to, or a
competitor's, now's the time.
We've encountered a couple of "scope-in-a-probe"s before, but they've been USB creatures. Here's a review of a truly self-contained model, but unfortunately, the diagnosis is not great.
If you need a relatively sensitive, low-noise input on a scope, the
Rigol DS2000 series is worth a look. The V/div goes down to 400µV.
Can't get enough about the VintageTek museum?
Here's some coverage, from EDN's great new site.
Scope Junction frequenter AlanAtTek has produced another interesting video. This time, it's a poor man's curve tracer, apparently known as an octopus (that's news to me).
Read about some of the technology found in a
33GHz scope on the EE Times site.

My colleague Rich Quinnell over at sister site Microcontroller Central is running a
design contest that could net you an Android accessory development kit! This is a great opportunity if you're interested in participating in our
SJOSHPO project and think an Android version would make for a cool side-development.
These Rigol 2000 series scopes look interesting. 12 bit resolution at slower timebase settings (5us/div and up) should appeal to people working on audio circuits or on switching power supplies. Also like the bigger screens - they now really give the "big guys" a run for the money. 50000 wfms/sec used to be gold standard for the midrange brand name DSOs until not so long ago...
Thanks for the video mention! Apparently it's called an Octopus because when assembled on a bench, you've got wires going off in multiple directions. The circuit's been around for decades, with many varients. Just Google "octopus component tester" and you'll get dozens of links.
