@Ice-Tea take that effing tape of the screens, why oh why do people stick labels etc all over the screens, it can ruin them, labels should be adhered to the body of the instruments, never on the front and certain never on the screens or displays

SDG1032X doesn’t. Same performance issues.

Which ?
Channel outputs are equal amplitude like SDG2042X.
Or something else ?

Harmonics and phase noise performance worse.

OK, Siglent specs are worst case so therefore always met however I can do these real measurements on a SDG1032X here using my SSA3032X if you like.

Thanks for the offer but the DG1022Z covers requirements here and is already qualified for me.

Just won another racal 9915 counter. That’s two now. Got a bliley ocxo left you see so needed something to stuff it in

I got the itch to buy something now but going to wait. Picking up that 475A and 2430 on Monday. And I think Invert is shipping me the 7704 and we'll meet up at a later date for the other stuff.

Well said! That was the first thing that crossed my mind when I saw that blue tape. I was really happy when the tape residue came off the 7075 with petrol, but not everything can stand being cleaned with it.

You're aware I didn't put them there I assume? I don't understand why auction monkeys put them on the screen as per default (or maybe I do: best sticking surface on any instrument). And if I ever catch one the act I'm going to do all Stephen King on him.

Just a follow up. The 2465 with the ugly arse fan modification is running cool, calm, and collected. Been running several hours and barely warm. Unlike it's older cousin up top which runs quite a bit warmer (Yes, it's fan is running).

I haven't done actual temperature checks yet but seat of the pants checks with human hand indicate all is well.

How well does the 7075 work?

Mine need several hours to become stable.

US$100 for a 5221A? Granted, it has options 02 and 03, badge, and feet, but wowzers.

Well, it's the banter of certain people on this forum (among others) that lets the world know that they regard Nixies as a desirable attribute and not a prehistoric pest.

Sadly, I've not had any time for TEA stuff recently as I've been building a big CoreXY 3D printer and fighting to get it printing as well as I know it can.

So the 7075 has been sitting there looking at me accusingly and reminding me of the Lemo connectors, PTFE screened cable and copper banana plugs sitting on top of it.

I gave it a good cooking after you suggested it last time and it's been sitting here in the most low humidity environment you can imagine. (A centrally heated apartment with the outside temperature well under -10C) I'm hoping to get the connectors fitted and some cables made up this weekend. I've also got one of RoadRunner's LM399 references turning up tomorrow, so that should be a good way to see if it's recovered from its imprisonment in a shipping container in southern England.

I'll let you know how it goes!

only a knuckle draggin' idiot would consider instruments containing nixie tubes as worth owning.

...I was working with the Performance curves here:
http://xx.leogroup.cn/DetailInfoEn/PumpDetail.aspx?SeriesID=9&PumpID=1923

But if ya look at the Rated Parameter specs under another tab on same page, the furking thing is only rated to Flow(m³/h): 4 ! 
Clearly it's running past its max comfort level but at this time I'm not sure who should be choked/strangled, me, the pump or the expert that sold it to me ! 

Thanks for your pointers Bean and the sanity checks that confirms I was thinking this all correctly.   

I blame the girl fumes!!! They HAVE  been known to travel right through the telephone waves; it's true ahh tells ya!!!

Please stop bleeding all over the floor; it's slippery and the hostess is refusing to serve us until it's cleaned up.

I haven't signed up yet. I guess I might as well. Add another to the pile of internet accounts...

That and website complexity is just atrocious these days. A well done basic HTML website serving up static content is far more usable.

Good maybe it's more efficient than the standard fan[emoji106]

[beanflying]

Yep, I'm right with ya on that suggestion and had come to exactly the same conclusion some hours before you posted.

That link above looks like they have cloned the Grundfos selection site and maybe even their Data too  Love a Chinese Rubbery Equipment Spec. with conflicting Data.

Gate Valve, Clamp Meter for the Motor. Pressure Gauge on the Pump Body if you are interested and manually test the Flow Rate over a known time going into your Tank up the hill. Record the data and write Ms Pump a Note about the Rubbery Spec. to be ignored by the Chinese manufacturer anyway

All seriousness though... what's the service here? Commercial? More than one household? That 4m³/hr translates to almost 18GPM American, and here typical is 5-12GPM for residential, with most being in the low side of that range.  And we are horrible water wasters.

Yikes. I know a guy who did that. Pretty much stopped any notions of being a pro athlete after college. Hope everything goes well!
