    More pulser action with some high speed digital logic.
    And more playing with the Agilent 81160A PFANG and Agilent 13GHz 90000 series scope.

      At 11:20, is that scope running Win7 in the background? Is this common on super-high-end scopes?

      And completely off-topic, have you heard anything about the “State of Electronics” documentary Dave?

      Thanks

      Yeah, most high-end test equipment runs embedded Windows – in this case, Windows Embedded Standard 7.

      It’s basically because at that price point, x86 is cheap as an embedded platform and fast enough (the scope hardware would probably be PCIe-based). Getting another processor is much harder.

      Plus, the PC environment means the software side can be done at the same time as the hardware side – you do your development using regular PCs and such with custom scope boards with full debug capability. Add to that the standard capabilities of network control and capture, VGA out, etc.

      The PFANG too runs an x86 system – probably running embedded Linux.

        Dave: that yellow-gold tape is Kapton tape – it’s a high-temperature mylar-ish tape. You see it on electronics near parts that get hot to provide electrical insulation without burning up.

        Very common for hobby activities as well – you put it on stuff you are going to solder so they don’t burn up, or if they do, it’s still insulated.

        Also – very expensive. A roll of that stuff can be $100 easy.

          Hey Worf, Kapton (Polymide) tape might be expensive on the Klingon Home World; but here on ebaY it runs around $8 USD for a 2 inch by 100 foot roll.

          A recent popular use for Kapton tape – “Makers” use it on their heated 3D extrusion build beds. Also, Kapton is indispensible for protecting parts of a PCB when doing difficult hot air rework.
