Med doesn't seem to have used it on his scope in the years he's had it. IMO it's been his sanity check when fixing stuff although he prefers to use a CRO. There's no doubt he got it for its advanced features of which it has few other than being a capture tool....it's a 15yr old design comparable wi...

That's the point about that scope's FFT: it is not sufficient to be useful. That may have once been the case and for the old SDS1052DL Mike has I would agree due to its very limited feature set. 1 MHz 0dBm via a 50 Ohm feedthrough into SDS814X HD Notice how many cycles provide far better FFT's. Scr...

I suppose this is much more meaningful? https://imagizer.imageshack.com/v2/xq70/924/CBdt7o.jpg To a point.... move the trigger level well within the waveform amplitude, pressing the level encoder will autoset it to 50%. Then you could go to a FFT exclusive display and examine the menu for axis scal...

OK gang, here it is. I have really no clue what it all means. Comments welcome. https://imagizer.imageshack.com/v2/xq70/923/pI9ECK.jpg You require a slower timebase setting on Siglent DSO’s when doing FFT. Experiment with 50 or more cycles on the display. If required I’ll pull out a DL when home in...

There's The Roundhouse in Fremantle. https://emmajaneexplores.com/visiting-fremantle-round-house/ It was built as a prison in the 1830s, but it was used for storage later on. https://www.youtube.com/watch?v=BOIpzSQq_Wk The Youtube video is only four minutes long. It gives good views of the courtyar...

The 635HV is another I'd never heard of - just looked it up - wow, 6 kV! Are the HV ranges just additional voltage dividers that you plug into and select a lower voltage range using the selector knob, or? (It's not obvious from looking at the pics I found online.) I do have a Simpson 269, but need ...

Equals additional protein.

And the date is..... March 31st :) https://www.eevblog.com/forum/blog/eevblog-1677-an-interesting-effect-with-fuses-(experiment)/msg5866735/#msg5866735 Not in OZ. They are first for the new year too... Nope, we Kiwi's beat them to midnight by 2 hours minimum. Perth in WA is a further 2 hrs behind NZ.

Smithsonian should I ever hang up the hat to have the time to go to the US for a week or 3.....probably would hunt out Mike and Paul while there too....

Mike, darn it, it's not like you to throw in the towel !

Are the actives socketed ?
Do you have a transistor tester ?

Has it passed the CAT scan Mike ?

No outside walkies for Harley then ?

Best wishes to you all from NZ and Siglent HQ.

I'm going to check it out on the bench tomorrow out of curiosity and see if it comes to life on reduced voltage the way the other one did. Famous last words. Football practice went for two hours instead of one and I was wiped out. Then the weekend was over and the work week began and that was exhau...

Yup with EU plug.
Scored one similar locally for my 131 that came with the 110VAC PS.

As for welders, I have four:.......... An R-Tech Chinese 180 Amp inverter MIG/MMA welder. It came with a five year collect and return warranty. I haven't used it for a time, but it paid for itself welding patches on my Ford Mondeo, now gone to that great car park in the sky. It goes down very low s...

Making the thread sticky was, IMHO, ill advised. Moving the thread somewhere was not something I noticed; I just use the "new replies" and "new posts" buttons. The "moderation" was a mistake and a bit heavy handed, but not especially surprising. The mod apologised and ...

It became far too cumbersome as a single thread . For instance someone might start a discussion on restoring an HP spectrum analyser, where he got stuck because a plastic cam switch was broken. That would turn into a discussion about various glues, whether it could be plastic welded, whether it cou...

add a 2S LiFePO balance/protection board, done!
Do you agree?

I do but Chris seems to want the easy way out with the least investment.

Yes a good idea that! Further thoughts to ponder on: Scope ON = solid color LED and/or flashing if being charged. Scope OFF but charging = LED in a flashing state, changing to a different but solid color when fully charged. It's getting whatever the shite charge controller does out of the box :lol:...

............. The intent with this is to "modernise" it. The original design is a 7.5V 4Ah (30Wh) supply which gives 3-4 hours of operation. We can do better than that now. So what I am probably going to do is the unthinkable and eviscerate the entire mains front end from it right up to t...

So you have it now and done some preliminary investigations but where are the pics ?
