content: Hi, I'm new to this forum, although I've been watching eevblog youtube channel for some years. So hopefully this will end up in the right category.I have an old Rigol DS1052E and I want to measure the discharge curve of a 18650 battery. I found out that choosing the longest time base (50s) will give me 10 minutes worth of data on the screen (12 divisions * 50s/div =10 mins). This is too short for me though. Is there any way I could measure for say 2 hours? I hope that there is a software for that. I was once playing with Ultrascope and I found it a bit dicky, but if you can control your oscilloscope through PC then there might be a way that you can measure for longer than 50s. The output format can be either a waveform or a CSV file with voltage and time measurements. Can somebody help me?Thanks

content: Thank you for your reply.Even though I was learning German at high school I have forgotten almost everythingYour program looks cool, but it looks like it only supports RS232 which I don't have on my PC/notebook.Why do I want to use oscilloscope for datalogging? Well because I have it and I know it is capable of doing it. I have couple of multimeters, but none of them has USB/RS232 connectivity. Most of the cheap datalogging multimeters have only RS232 which almost no modern PCs support anymore. Sure there are adapters but usually they don't work.

The easiest way are the FTDI Adapters, some PL200x wouldnt work on Windows 7 (driver issues) and higher. But these adapters you can buy for under 3.-. So there's no probem if the software is written for COM - ports or USB.I've checked this software and it works fine. So now I don't have a DS1052E anymore so I can't test it.Did you think about an Arduiono or AVR selfmade logger ? google it. Easy to find. checkout codebender.ccYou also can use a cheap bluettooth Adapter like thathttp://www.ebay.com/itm/HC-05-RS232-TTL-Wireless-Transceiver-Bluetooth-Transceiver-Module-TTL-to-RS232-/351510098671?hash=item51d7a272ef

The best option for me is probably the RS232/USB adapter. I used one 3 years ago but I wasn't able to make it work, so I thought that they don't work. I'll probably have to give another look.

If it doesn't work, for low-repititivity you can even do a workaround by getting screenshots and OCR that image.This way you can datalog like you want, for minutes, hours, days, months.

content: I use these and they working fine since years with all my devices. Watch out there's a FTDI inside, if you use Windows.http://www.ebay.com/itm/5Ft-USB-2-0-to-Serial-9-pin-DB-9-RS-232-Adapter-Cable-with-FTDI-Chipset-/151280818541?hash=item23390a196d
