timestamp: January 01, 2025, 12:28:22 pm
content: I am in the process of re-capping the power supplies of a Tek2445B and a Tek2465B. My question is this: The two 290μF 200 volt main caps test good on my ESL tester. They measure at 313.8μF 0.09ESR and 311.5μF 0.07ESR. The date codes say they are 31 years and 33 years old. Should I replace them or leave them alone? How much life is left in them? What is the consensus on this forum?

content: I don't think you're going to find a consensus opinion on replacing capacitors just because they are old (aka "recapping").My opinion is to leave them alone unless they are determined to be bad through troubleshooting, visual inspection, or direct testing. Some manufacturers, such as Tektronix, provide AC ripple specifications for DC power rails which can help determine if replacement is needed for the main filter caps.One exception in the 24xx series scopes is the RIFA capacitors near the AC input on the power supply board. It is not uncommon for them to explode due to age and take other components with them. Be particularly suspicious if they are severely yellowed and/or show signs of cracking. You can search around for recommended replacements on this forum and others such ashttps://groups.io/g/TekScopes.

content: My rule is that I only replace capacitors if I have a good reason to believe they're bad or getting close.If the caps (or the PCB in that area) show signs of running very hot for long periods of time (PCB darkening, yellowing or shrinkage of the plastic covering on the cap, etc. The only other time I'll replace them no matter how well they test is if I'm dealing with high-hour equipment in a mission-critical application.Otherwise, leave them alone. It's really quite rare that I see big snap-in caps fail unless it's a really harsh application, which this isn't.
GPIB / HPGL Plotter emulator for Linux - Page 1

content: FWIW I've written an HPGL plotter emulator for Linux. Once the plot is sent from the instrument, it can be printed or saved in several file formats.I've tested it on an HP8595E spectrum analyzer and HP8753C network analyzer.The GPIB adapter (on the computer) must be capable of acting as a listener / talker. (Some devices will only act as a system controller.)Available for download fromhttps://github.com/VK2BEA/HPGL-Plotter

content: Looks like a Linux-friendly alternative to the otherwise excellent tools from KE5FX. I'm curious about the requirement for gtk4, though.. does this imply that it's a GUI-only application? I'm very interested in something that can pull plots via a USB to GPIB adapter without requiring a full-blown desktop. Think Raspberry PI being connected to the instrument, but only ever viewing the plots on my PC. Is that possible with your tool?

content: If your adapter is supported by the Linux GPIB package, you could use the "ibterm" command to send a plot command to your GPIB device and capture the HPGL output. ibterm is included in the package. A small amount of massaging on the output will be needed, such as removing ibterm's prompts, which could be handled by a simple bash script.The output could then be moved to your PC and viewed with the KE5FX 7470 plotter emulator which can be used off-line. Off-line operations (meaning no GPIB access) work fine under wine.Alternatively, you can use hp2xx to convert the HPGL output to PNG, JPG, or a number of other formats, and view that resulting file. That's a pure Linux solution, but KE5FX 7470 handles more of the HPGL command set, which might be needed for your device, and in some cases looks better.

content: I just found another issue. Yes i am sorry for finding another one. Spending too much time with this device. Please dont kill the messenger!First it looked like a trigger issue, but then it came apparent, that it is not.Trigger is stable, but it looks as it isnt. Even the mask test fires on it! Strangly, there are no trigger failures to be found in the history. The issue seems to dissappear, when one normal channel is deactivated, or a math channel.Another interesting thing:The perstistence has the wrong color (blue) in the other setting where it should be red.Any change to the formula has no effect!Workaround:Dont use 2us/div! It seems to only happen with 2us/div.

Choosing a USB Tester: Atorch UD18 vs UD24 - Page 1
Forum section: electronics / testgear

author_rank: Regular Contributor
timestamp: December 27, 2024, 10:58:41 pm
content: I have been trying to find a budget USB tester, but it's surprisingly hard to find actual reviews of these, especially in English.I had narrowed it down to three models, the UD18 and UD28 by Atorch and the MakerHawk tester.I was originally looking at a cheaper and much more limited Atorch tester, but then I realized that they have an official(is it? Or someone pretending to be them) storefront on Aliexpress where it's much cheaper and I can get a better model.UD18https://www.aliexpress.us/item/2255799815102766.htmlUD24https://www.aliexpress.us/item/3256801282103209.htmlMakerHawk:https://www.amazon.com/dp/B07DK6FT4QI do like that the MakerHawk one appears to be made in the US and has some better build quality, but it says it only goes up to 3 Amps and I want to test for up to 5 Amps of draw.I tried using YouTube first to look up reviews of these three testers. Problem is most of the views weren't really a review on if the device is accurate, works properly, or has any issues but more of an unboxing and just using it to show that it works (half the time with the person not even knowing what they were doing half the time). The others were not in English... Even after all these videos I can't even tell what the difference between the UD18 and UD24 are other than their shape, even their price is roughly the same.A lot of the videos also called them the "Mustool" brand devices, but when I try to look that up I can't find much. Did Mustool change their name to Atorch? Or are the Atorch versions bootleg knockoffs of what was once Mustool?Then I tried Googling written reviews, but that was fruitless. The first result was from a four year old post on this very forum, but it was mostly unanswered and talked about different testers even though the Atorch ones I was trying to find information about were in the topic title. Other results were mostly the same, other forums or reddit posts that dies out after a small amount of replies that didn't really talk about anything or talked about entirely different devices.So can anyone give me advice on these three? Or anything similar around the same pricepoint? I am just trying to test several USB A and USB C chargers for how much voltage and amps (up to 5) they can deliver as well as how much of that voltage/amps several of my USB devices draw, not trying to engineer a professional device down to 0.001 precision of voltage.

content: I've been shopping for a rugged portable oscilloscope and have been looking at the Fluke 190 series.I am having a hard time finding a good usability comparison between the series II and series III models.How does the usability and responsiveness of the UI compare between the two generations?I think the record length is the same, which is pretty shocking given that they were released a decade apart.The two generations appear to be largely the same apart from the higher res display, 1000V/div, and wifi connectivity of the later model.Is it worth getting the series III given how relatively inexpensive the older series II models are becoming?Also, does anyone have recommendations regarding the 2 channel + DMM models vs. the 4 channel models? More channels seems better but the ability to have a handheld DMM with trend plots also seems useful.

content: Did you fix this issue already?Some Agilent and Tektronix machines like to play hard-to-get with this issue, but don't worry—here's how you can put them back in line:Start by unscrewing the five sneaky screws at the back. Two are hiding behind the handle, and two are undercover beneath the black circular rubber pads. (Yes, it's a game of hide-and-seek.)Grab your needle-nose pliers, give them a soft cushion with a cloth, and gently evict the power switch from its spot.With the power switch out of the way, the casing will surrender and open up.Inside, you'll find two ribbon cables. Treat them to a spa day with some contact cleaner/lubricant, then slide them back into place like a pro.Problem solved, and your machine will be back to behaving itself in no time!
Riden RD6006P Constant Current Accuracy - Page 1
Forum section: electronics / testgear

author: dlipter
author_rank: Newbie
timestamp: December 26, 2024, 04:16:29 am
content: I am looking for a current regulated PS that has accurate tight regulation in the 5-25mA range. The Riden RD6006P has a display with a current resolution of 0.1mA which makes me think it might be designed to accurately regulate current at a low value in the 5-25mA range. Any light shed on this question would be greatly appreciated. The ability to display a small value of current doesn't necessarily mean it can also regulate that small value accurately in a steady fashion with a time varient load. I want to maintain a constant tightly regulated current in the 5-25mA range over time with a slowly varying load.Dennis

content: Yes, the RD6006P can perform low current regulation quite accurately. In addition, it can be calibrated. I haven't calibrated my RD6006P, but it comes out of the box fairly accurate.I simply connected it to a Brymen BM879 power supply via a 410 Ohm resistor and took a few pictures.

content: Sonpul,It looks like you are demonstrating that the RD6006P accurately displays the load current value. The second question is when you set it for let's say 15mA and vary the load of 410 ohms to a higher value, does the RD6006P maintain a steady 15mA? If you used a variable resistor as a load and monitor the current while changing the load to 500, 600, 1K, 2K ohm...etc, does the 15mA remain constant?

content: Quote from: dlipter on December 26, 2024, 10:51:57 pmYes, it continues to support the specified current.Perhaps after calibration, the compliance with the specified current will be even better.I have the first revision of this hybrid unit with a linear output. Now, as I understand it, 6006P can work on a four-wire system with compensation.My firmware is from Unisoft. If I understand correctly, this firmware is not available for RD6012P if you like the firmware but need a more powerful power supply.RD without the "P" index is not very interesting due to higher pulsations and therefore I cannot tell you how they behave.

Is it too low or too high?The MAN'X TOP was probably operated by 9 volts, but I'm not sure if this applies for your model, too.https://www.radiomuseum.org/r/cda_digital_analogique_multimeter_manx_top.html

content: Hi!I got a Consultronics DLS 200 in my post box and it came with only one of the two discs that are normally with the unit.Looks like the Disk I have is the ETSI-HDSL for different wire configurations. There should be another ETSI-ISDN software disk that is missing.My unit had a flat battery, that I changed. After running the self-test multiple times, all relays seem to have settled and working except one or two on a card that I have to identify later.So my question here in the forum, does anyone have additional information about these units? I did find a manual on repeaterbuilder. But I still miss the parts of the software / floppy images.Also, there should be a service manual for that unit. Would be really to have one. And if it is only to build sort of a Gotek replacement for the floppy driive.Thanks in advance!Astralix

I dont know how much voltage but obviously enough. Well, I killed something because now my signals are very tiny and ugly looking. Both channels seems to be affected but only channel A got blasted. Is this worth trying to repair? What is the first thing that got hit? The amps under the heatsink? What to check first?

Seems like the amps is letting the full rail voltage right through. When I adjust the amplitude above 5 volts it clicks the relay and I get full 12 volt on the output. Well I try to change the THS3002I amp and see if that is enough.

Then I used a thermal camera and found a blazing hot 7905 voltage reg next to a AD8009 opamp. I ordered 5 of these opamps too so replaced that one and that fixed the problem!Does not seem to be way out of calibration either so I will not bother with that and might mess something up. I'm happy to have a working signal generator again!

I was really hopeful that any issues it had were on the PC side of it, since I'm very comfortable with IT work... unfortunately the PC side of the scope is fine, but it appears to have issues with the acquisition board.It fails diagnostics with the error "ADC Connects: 372" (I posted a small clip to youtube here:)Channel 1 will not display any waveform. Channel 2, 3 and 4 will display a waveform, but if if you try to display either two or three of them at the same time, only one shows correctly.I'm wondering if anyone can shine some light on what this specific error means, or which specific area of the board to check out (I'm guessing the two ADC chips) I know there's not much hope for repairing the acquisition board but perhaps it's some sort of issue with a passive component.Also, does anyone know if the TDS5054B-NV has the same acquisition board as a regular TDS5054B? I'm trying to find one with a busted PC side for sale...to scavenge the acquisition board out of.Here's a stock pic of the acquisition board from xdevsThanks!!
