Well, I bought a new scope. 1Ghz TDS784C for 66,483 yen.
I think I'm at, what... 11 scopes now I think? I should sell some....
And for dessert, I bought a 334A Distortion Analyzer for 12,800 yen too. ![Grin ;D](https://www.eevblog.com/forum/Smileys/default/xgrin.gif.pagespeed.ic.QVVz6XIT20.png)
(Photos from the listings).
One step further down the calibration rabbit hole, now I'll fix this stuff up, to fix up the stuff I need to use to fix up the stuff I actually want to use... Possibly with a few more steps of fixing stuff in between..
Soon I'll have all the gear ready to re-calibrate the Tek 2467 scope I accidentally wiped the cal memory on when replacing the backup battery.... ![Broken! :-BROKE](https://www.eevblog.com/forum/Smileys/default/smiliey_scope_broke.gif.pagespeed.ce.z9RuKVWKjY.gif)
Such is the great circle of life TEA. ![Grin ;D](https://www.eevblog.com/forum/Smileys/default/xgrin.gif.pagespeed.ic.QVVz6XIT20.png)
Unless I'm badly mistaken about current exchange rates, that's a pretty damn good price. Congratulations!
Yeah, not a bad price for the 334A, considering what they were selling for here last year, I wrongly thought prices had dropped back to normal, as one made just over £50 this week, looking more closely it was a bit of a mess, with glued together panel meter and crusty flaking dial. ![Laughing :-DD](https://www.eevblog.com/forum/Smileys/default/smiley_laughing.gif.pagespeed.ce._hfWAz_QHO.gif)

Ahh yes, I remember it well.....
We had quite a few of these in my old work years back.
As a lab instrument, they are really good, but frankly, in some Broadcast testing situations where you are doing distortion tests on a lot of sources under time constraints, they are a "pain in the bum!"
At one multi-transmitter site, they replaced much older manual instruments where, if we did an initial "null" on the first of multiple programme lines & Mod monitor outputs, we could just consecutively test across all of them, without having to touch the distortion controls.
Along came the 334a, & we were told "It's just 'the duck's guts', you don't have to manually null it!"
Unfortunately, it treated every test as if it was "the first one ever", & would painfully & slowly do its thing, burning up time.
Even if you did manually null the thing, it still needed "auto" to get a really deep one -------still painfully slow.
After some years, they were replaced in that installation by AWA "N & D sets".
These were also auto but had a very fast null, unlike the
hp.
This soured me on the 334a, but they were OK in other installations where a single or maybe two sources needed testing.
