content: Hi,I've transitioned into a role as an embedded software engineer in the automotive industry (before that I worked a little higher up the stack on Linux drivers and userspace applications).I work from home two days a week and need a simple oscilloscope for the times when I need to verify if bad SPI/I2C/UART communication etcetera is due to electronic problems.Most of the time I get by just fine with my DreamSourcelab logic analyzer, but now and then an oscilloscope would be useful for comparing logic levels to actual voltages when powering on a device or putting it under heavy load.Another forum posts asked about the Dscope oscilloscopes but that was a previous generation:https://www.eevblog.com/forum/testgear/is-dscope-(usb-oscilloscope)-a-good-first-oscilloscope/With the new generation, they've improved the specs (100Mhz, GSa/s, 2M record len)https://www.dreamsourcelab.com/product/dscope-series/Has anyone any experience with these products? I can not spend more than say $300. Should I go for a Siglent/Rigol instead? (In a dream scenario I would afford a Keysight DSOX1202A and get segmented memory and fast MSO capabilities but that's $1000).

content: Hi,All protocols that you have listed are low speed.Therefore, DSCope may well complement your DSLogic.Athttps://www.dreamsourcelab.com/download/you can download the latest version of DSView v1.1.0https://sigrok.org/wiki/DreamSourceLab_DSLogic_Prohttps://sigrok.org/wiki/DownloadsSigrok has planned support for DSCope.I have both - DSCope & DSLogicPro. All needs are quite satisfied.I advise you to supplement your workplace with a good programmer.Or at least these:https://www.embeddedcomputers.net/products/Vladimir.

content: Hi Vladimir,Thank you for your answer.1. Which DScope model do you have?2. Have you done any accuracy measurements to compare it another oscilloscope?3. Do you notice any lags in transfer over USB (with my DSLogic I'm impressed with the fast transfer rates and I'm hoping that the workflow with the DScope will be just as fast)?4. What are the weaknesses compared to a regular bench scope such as Rigol DS1054z?5. The DScope does not have a fan. All scopes I've used have had loud fans. Do the device get hot during operation? I really like the idea of having a scope that is dead-quiet.6. Is there an API for automating measurements?

content: I have a DSCope 200 MHz scop (USB2.0), I need to understand that this is a virtual device.There were many kinds of things, but I am not going to refuse from analog devices.I have Fluke199 - it’s very convenient when there is an autonomous power supply, there is C1-97 (350MHz).Of course, it’s more familiar when there are controls. In general, there is something to compare.It all depends on the tasks performed.I wouldn’t compare it with DSLogic in speed, Xilinx controls there, and DScope itself is quite informative for simple tasks.I find disadvantages in my own habits, it’s hard for me to judge.For me, the needle of a measuring device is much more informative than DMM.DScope is by design in the same case as a DSLogic without a fan. The downside may be that you need to open two sessions (borrow 2-Two USB) - there may be brakes.The API can be offered to be done on Sigrok - there are many enthusiasts who post on github.
