RIGOL DS1053E - Page 1

content: Dave - I am new to Blogs but enjoyed looking at a couple of your technical reviews. I have an old TDS210 and the DS1053E looks really good as a replacement, but does it emulate the Tek's clitch capture mode? I use scopes for analogue transient work and at RF frequencies and when looking at AM modulation, many digital scope present you with display aliasing even thou they have fast sampling and good memory depth unless you drop into glitch capture mode before looking at the modulation at an audio based sweep rate. I have scanned the net but I couldn't really find out much detail on the RIGOL. I might HAVE to get one, but I still wont be throwing away my Tek 485 & 7306 mainframe analogue scopes.

content: Ray,Thanks for that info. How the TDS210 manages that info in practice to make sure you dont lose the information as you "pan out", is to check 10 points and throw out all except maximum and minimum points so you dont accidently "lose" the glitch as the machine tries to display the total memeory information within the resolution limits of the display.cheers Noel

content: The long memory (as long as you don't require max. sample rate) helps with this, so peak detect won't be as necessary (it can just store all the samples). If you do require peak detect, check if it supports sample rates all the way up to 1GS/s. On some scopes, peak detect doesn't work at the highest sampling rates, which makes it much less useful in my opinion. Also check out the competing Instek model, it could be superior in this application (supports long memory even at 1GS/s if I recall correctly).

content: alm,Thanks for the advice. I noticed from the RIGOL specs athttp://rigoloscilloscope.com/digital-storage-oscilloscope/rigol-ds1052e-50mhz-digital-oscilloscope/prod_2.htmlthat total memory depth is 1MB but athttp://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=180568556086&ssPageName=STRK:MEWAX:ITthere is a table which indicates options between sample rates and memory depth and it is not clear whether the DS1052E can do both in glitch capture mode. I realise the memory is deep but the issue with most old digital scopes with lower resolution displays was display aliasing. (In other words you lose the visual indication when you zoom out even though its still in memory.)

content: DaveI just read that the Hakko 936 has been discontinued. It has been replaced by Hakko FX-888.http://www.hakko.com/english/discontinue/index.htmlI think you will have a field day with some of the marketing hype they are giving for the change. I would love to hear your take on these clames. As I read some I thought to myself "did they really say that".I always wanted a soldering iron holder that was 30% quieter. I am having "fun" picking a color also.They reduced the footprint on the FX-888 but now the holder is not stackable like the 936 was, so whats the gain?You should do a mini segment on the 936 vs. FX-888.Bearman

Now that energy efficiency is more important, proper thermal design can reduce the energy used to operate the fans.And if there's a heat pump, parts of the system can be below ambient. There are also heat pipes that have a positive but somewhat nonlinear delta T.

Going beyond #35 NiMH and NiCd Battery Charging Tutorial... as in *help please?* - Page 1
Forum section: electronics / general

author: kaptain_zero
author_rank: Regular Contributor
timestamp: August 17, 2010, 03:41:20 am
content: Dave,I very much enjoyed your treatise of the NiMH and NiCd battery charging videos. However, there is a newer chemistry available called LiIon (and LiPo etc) that is out there, and it's causing all sorts of confusion. Personally, I was introduced to LiIon when it came to High Power LED flashlights and most of the LiIon cells and chargers I've been able to find are available from Asia with their questionable build quality. Over on the CPF forum, there are stories of flashlights behaving as pipe bombs due to inappropriately charged LiIon cells and or bad chargers and for that matter, simply badly made LiIon cells. Much of the chatter around these cells/chargers recommend purchasing a DMM to check the final charging voltage, with much focus on that a proper charger MUST do CC/CV with a complete cutoff of charging with no trickle (according to some cell manufacturers) and yet most Asian built chargers seem to mimic the CC/CV algorithms which is apparently "bad" and so goes the story. Then we have users buying $10 LiIon chargers and 2 for $5 14500 LiIon cells, only to purchase a cheap Asian made DMM to verify that that the charger stops charging at *EXACTLY 4.20v* as apparently going past 4.25v would turn a perfectly good battery cell into a "terrorist cell"! (Even I know that cheap and even higher priced DMM's are going to be less that perfectly accurate when we get into the lower Milli volt range).We (though it's only me asking on behalf of the high performance flashlight community) need someone with some *real* technical/electronics knowledge to step up to the plate and tell us the way it really is without the marketing BS.Personally, I don't trust my $10 lithium Ion charger any more than I trust my $10 Asian made DMM and so I have done my own homework and had my DMM checked against certified equipment so I know where I'm at, but I'm ONLY a lay person with enough of a background to know that I'm in the weeds here and need to rely on more qualified people to tell me what I really need to do to stay safe....Here's hoping for some answers and maybe even a video blog on the topic, considering how much you enjoyed that Fenix LD01!RegardsChristianakaKaptain "All I ever do is connect + to - and I run everything else to ground" Zero

content: Hi Dave,this is my first post in your forums.i'm from Israel and i started to watch all your video blogs in youtube and when i watch this video i came out with an idea. maybe you can put a full solar panel on the other side of the calc on axial that way to can get your 100mA to your lcd (see pictures)just a quick search in ebay and look what i foundhttp://cgi.ebay.com/6V-100MA-0-6W-small-solar-panel-diode-inside-/320561796187?cmd=ViewItem&pt=UK_Gadgets&hash=item4aa2f8d45bi admit this fairly big but i'm sure that you could find a better one smaller and more efficient.good luck and keep up the good workIdo

I can get the same effect many ways, I just found the chair a consistent method.People think it's all sorts sorts of things like the piston in the chain resonating and all sorts of weird things, it's non of that, it's simple static generation.The real mystery is how it actually manifests itself in the front end of many different scopes so consistently.Dave.

My chair is fixed with nothing moving.At the end he even used a terminating resistor and still had it resonate but it was at a slightly different frequency, as I would expect. Without the complete probe your LC tank has completely changed and I would expect a higher resonant frequency.Just my 2 Cents.

content: Out of curiosity, I measured a local cell base station power level with a spectrum analyzer and got about 140 nW using 500 kHz bandwidth, just using some wire as an antenna. Here is the result:With that kind of power, one would need for charging the 5.6 Wh battery, about 5.6 Wh/140 nW = 40 million hours of charging time (assuming no losses anywhere), which is about 4500 years. I suspect that the battery is long gone before the charging is completeNote that 140 nW is actually quite high received power level, since it is equal to -38.5 dBm. IIRC, GSM spec requires -102 dBm (63 fW). It is left as an exercise for the reader to calculate how long the charging would take with that minimum power levelSlightly similar topic, I have also seen in my antenna book, "Antennas For All Applications", mentioned that it would make interesting solar cell, if one could rectify the sunlight directly (after all, it has an electric field component). Again, with perfect diode it would reach 50% efficiency, which would be a record-breaking figure compared to conventional solar cells. But, unfortunately in reality rectifying light is quite impossible with current technology, since there is nowhere near fast enough diode available to do that (electron relaxation time etc).Regards,Janne

By then the number 2 overtakes ya.There is a business ethic that stipulates one should never rest on his laurels of he'll fall behind. Maybe, in business, it has a bit to do with having a giant ego and behaving like a ignorant moron as a result.Also, something a marketing guy told me once a long time ago.. The pitch the marketing folks make to the MD's/Execs/CEO's is aimed squarely at those people in the meeting and not some buyer of any products.It's not and easy problem to solve unfortunately.

I bought a set a couple of weeks ago from Farnell (code 389-0557) for £43 and I love them. I have just found out that they are exactly the same as the Pomona 6275 available from Farnell for £20 (code 413-5799). I assume the Flukes are a rebranded set from Pomona. It seems I could have saved £24! Hopes this helps someone.Tristan

content: Just thought I would share some comments on the Fluke 289, I've owned one now for a year, I totally agree Dave, it's to big and cumbersome for an everyday meter. On my workbench I use the newish Fluke 233 and a older chinese built (freeby) Fluke 19 for second measurements when required.Out in the field I use a Fluke 117 and a Yokogawa AC/DC Clamp, just quickly the 117 is by far the best field meter for an Electrician/Tech one could buy, but Fluke stuffed one thing up with this meter and it bugs the hell out of me every time I use it, the continuity beeper is piss poor, its way too quite to be heard above any sort of machinery, why Fluke did this is beyond me, its an Electricians meter we work in noisy enviroments get it FLUKE.Anyway back to the 289, let me get some the anoyances out of the way, cumbersome and lacks display contrast and that it for me. The likes - I love this meter when all the other meters give in this one shines through, whether it be measuring low ohms (motor windings) or even high ohms - try measuring 100Mohms with a normal meter. The low Impedance function is very useful, even Hold has two functions (normal hold and touch hold) brilliant, diode test yes it can measure a cree, seperate AC and DC mV switch positions, 50000 count which over ranges to about 53000 - this is great if your measuring a value around 50, it dosn't up range a drop of a hat like other meters do, the save function is the main use this meter gets, the ability to store and graph continuous readings is invaluable in my field of work and is worth ever cent spent, a minor let down is the windows based software, it does the job and thats it, it could be more user friendly, I find myself copy and pasting a lot in to Excel. Brilliant job Fluke, 5 stars +.
