content: Noticed a potential bug on KS MSO-X3104T scope when trying to save CSV waveform file to USB disk. Scope has the latest FW 7.65.20241205Setup to save CSV waveform (max points, with full descriptions) to USB diskSet Acquire mode to either HighRes or AveragingEnter zoom mode, try to save - seems to workEnter zoom mode & enable FFT, try to save - "ERROR: File not saved" consistentlySame data is saved when not in zoom mode. FFT & ZOOM & (HighRes OR Averaging) is a suspicious comboCan anyone confirm this on MSO-X3000A, X3000T, X3000G models? These have similar FW and HW.

content: Certainly a bug then. I rechecked - saving with "CSV data (*.csv)" option causes the issue in any acquire mode (normal/peak detect/high res/avg) with FFT and ZOOM (main 100us/div, zoom 50us/div, ch1/ch3 on) in stop/run.I contacted KeySight support, will see where this leads. Additional reports to KS would be welcome.

content: Im having a time with having two active markers that automatically track the highest point & the lowest point. I am setting up marker one for duplexer high frequency. Then marker 2 for automatically tracking the highest point. Then on marker 3 is the low frequency. Marker 4 is to track lowest point.But I can only seem to get one marker to ever stay active & automatically tracking at a time. Its frustrating to have to keep telling it what to do when I change where I'm focusing tuning.To set markers for automatic im doing the following. Marker/select marker 2/peak/search config/peak type. Then back out of search config & selecting cont peak.I do that for markers 2 & 4. But only one marker at a time ever stays automatically doing what I want it too.SSA3021X plus
Suggestion for a food safe PH probe - Page 1

content: Hi, I would like to acquire a ph meter, mainly to be used with food, e.g. controlling the acidity of milk while making ricotta.But I'm struggling to navigate between the many options in terms of electrode type and price range.My natural inclination, having a mild form of GAS, is to look at old meters such ashttps://www.ebay.it/itm/167019481568orhttps://www.ebay.it/itm/196522059138,but they often do not come with a probe.Actually, I do not think I strictly need a meter; I think I can use my HP3456A or other 6.5D meter with some math.Does anyone have a suggestion for what kind of probe is more suitable for my use case? It's a plus if it's moderately priced...thanks!

content: Hello everyone. Wish everyone a good day.I am currently having this problem and hope to get help from you.I have an Agilent DSO80k that just had a broken MB. The motherboard code is Intel D915GUX. I tried searching locally but could not find the exact code, I tried other mainboards like Intel D915GRV/GAV,... but when installing the program, it always reported an error as shown, causing the installation to fail.When I got to the Matlabs installation window, I did the trick by installing it directly from the TEMP folder, but when I finished installing everything and restarted, the software continued to report an error that the file "sicl32.dll" was missing as shown. On my old mainboard, the software installation took place without any errors, but when I switched to the new MB, this problem occurred. I am using Windows XP SP3. Can you help me? Thank you very much.Sincerely,Feng.

content: Hello,I have a question and don't know if it is correct or not.I have subscribed and watched many videos on Dave's youtube channel, lots of knowledge and information. However, I have a question: Dave seems to be very biased towards the Rigol oscilloscope and has no sympathy for Siglent. I only found videos of Dave disassembling the Siglent, but no videos reviewing the full functionality. However, there are many videos reviewing the functions of the Rigol oscilloscope in detail. Perhaps Dave is afraid to directly compare the functions of Siglent with Rigol, for example the DHO804 and SDS804x HD series. Still waiting for Dave's full video review of the 12bits Siglent series, not just the disassembly.

A far more generic product would be something like a camera satchel; if designed well then they should provide as much protection for your 'scope as they do for a camera.Often they have removable inserts to open the internal space up, or for creating your sub-compartment for probes, PSU, etc.It looks far better too. I use a camera satchel for a portable data recorder, for me it was a way better option than the manufacturer-suggested case.(I have no idea what the attached example is like; I don't have that one).

However, if a remote control app sends anything to the meter (logging or any commands), it will take control back to remote land. Then you can hit shift key over and over again to watch control bounce back and forth. 😉

Building out a workbench for a new job? - Page 1

content: Hey guys! So I just started for a company where they just created this position for an electrical engineer. They currently don't have much equipment as they are a scale model making company that usually has had most of their work go back and forth over seas. I'm in the USA so naturally now they'd like to limit that, thus my position was born. So I'm tasked with building up a work bench to be able to develop PCBs for the scale models we make and do.However they're also not looking to go bankrupt on equipment. So I'm wondering what others would all for that would be reasonable? There's so many different pieces of equipment what would be good for smd work? I'll need to measure capacitance and resistance of 0605 components, maybe even smaller, reflow work, as well as be able to test. So far I've had them pick up a hakko 888d soldering iron, quick 861dw hot air station, I'm thinking a fluke 87v multimeter and an AmScope SE400-Z microscope. Maybe a Korad KA3005P programmable power supply? Then of course all esd may...How's that sound? Anything else I could need or better options? Don't think I'll need an oscilloscope yet. Lemme know your thoughts.

As you progress, you will know better what your equipment needs will be. Your Fluke 87 will measure capacitance and resistance, but can't do ESR or inductance, so you might want to keep that in mind and check out LCR meters. Find out from your Boss what your budget will be, so you don't overstep your bounds. Good luck with your new job, and may you have great success

I think at this time things are basic enough I won't need esr or inductance capabilities, but will definitely keep that in mind.I did ask them what kind of budget we're looking at, and they're aware of how expensive things can get but really have no exact number in mind. They've easily spent 10s of thousands on 3d printers, but I definitely don't want to overstep or over purchase for my own needs.Really I will need a suggestion for measuring components as small as 0603.

content: I've successfully used hot air on some R&S glued heatsinks so I can endorse the strategy.At the risk of stating the obvious: use lots of heat and get your blade / screwdriver between the FPGA heat spreader and the heat sink, rather than between the board and heat sink. The epoxy always dropped to near 0 strength long before the heat sink got up to reflow temperature and required very little force to pry. It stinks up a storm long before it loses structural integrity, though, so ensure good ventilation.Good luck, but if your epoxy is like my epoxy you probably won't need it and there is nothing to fear

My '15 123 looks virtually identical to your '08 125.According to the Fluke 123/124 Service Manual the PCB is the same between both models (the 125 is not covered). So, in theory it should be possible to upgrade the 123 to at least the 124. I don't think it makes sense to do it for the extra bandwidth (it's only 25 MS/s so the 20/40 MHz spec is a stretch), but unlike the 124/125 the 123 does not have cursors. That would be a nice upgrade.

It was acquired for some EMC pre compliance work, and I think it paid for itself several times over, from what I hear.I don't know if eBay is the best place to advertise. I'm in North London (UK). It's way too heavy to ship. Well, it's too heavy for me to consider shipping, at this stage.I'm not sure what it's worth.Does anyone have any suggestions as to the best method of it moving to a new owner?Thanks for reading.P.S. I also have an 8595E, a 5343A and a 54616B digital 'scope. I also need to rehome these. Ideally somewhere that will appreciate what they are.

England isn't that big of a country and western Europe isn't that far away either, so it shouldn't be too difficult for a buyer to come and pick it up in person even if they need to rent or borrow a car to do so.Istronglyprefer to pick up large heavy TE myself any time that I can. But I'm on the wrong side of the pond for this.Or you can just set a price (with the same provisions) and put an ad on here and see if someone is willing to buy it.
