I have recently acquired a Dynamco D7100 analogue oscilloscope without a user manual. As this is the first time I have owned or used an oscilloscope I would like to try and find an instruction book. The manufacturers no longer hold any information and a Google search only found one site but when I downloaded a 'service manual' all I got was gobbledegook. Any help would be gratefully appreciated or even pointers to a generic manual where I could learn more.

'destitute' why would my financial situation affect this, however the answer is no I'm not destitute. Your first link I have already discovered and it's a list of links to other pages but when these are downloaded it's meaningless characters (as English is my first language,
maybe it's just a language I don't understand).
The second link looks more useful and is the sort of advice I was looking for.
Thank you.Comment

the 1st link downloads a zip containing 3 pdf files.

calibrate your probes . then randomly twiddle knobs and look like you know what your doing . well it works for me . volts per div should get something to start with .Comment

scopes are like 3D printers for me,
every time i get one the first thing i do with it is try to fix my previous scope!

I read EBOOK of Testing Electronic Component and found that
"In order to test the small blue resin coated ceramic disk capacitor which has 104 50v specification,it is possible to test this small ceramic capacitor by making use of analogue meter.
Set to times 10Kohm that has 12v output from the probe to check disorder of ceramic capacitor.
It is not uncommon that testing result of digital capacitance meter is okay,But It show shorted reading when you check it with analogue meter."
Is it really possible to test small ceramic disc capacitor with analogue... -
I am trying to fix this item, it works except I can't get it to pair. Searching online hasn't found a manual for it. I am wondering if the Bluetooth module is faulty as it works in analogue audio mode.
The module has two rows of castellated pins for a total of 24. It uses the CSR 57F68 chip together with a flash chip for storage. The main board has an amplifier chip, stereo mixer, power supplies and a microcontroller which seems to have no markings. I think the microcontroller is working correctly and sends commands to the Bluetooth module via SPI although I don't know the protocol...12-24-2024, 09:47 AM -
Repair manual part number 702_58300000148618_ara_en_a
It took way too much effort to find this manual so I am sharing it here so the next person can find it easily. Also, I am mad at Bosch for not publishing it on their website, so they deserve to have it leaked....07-14-2025, 07:36 PM -
Hi Guys,
Weird one here. I have a special GPU made by DFI (Model LS3440) from an Arcade gaming machine. The GPU uses the S3 440 GTX Chipset, and has dual DVI-I ports. For some reason, the analogue has stopped working on both outputs (DVI-I to VGA cable). DVI-D and digital outputs work fine, just the analogue that has stopped working.
Now, I could get around this by using Active cables to convert the signal over to Digital, but its got me wondering exactly what the issue could be. I have inspected the GPU and DVI ports under my microscope, but nothing stands out. Because... -
