Also, many features are hidden deep within the menu structure see the screenshot below for an example and other features such as zooming the horizontal scale on a captured trace are so convoluted that you tend to skip them. A minor annoyance is that my DSO has a permanent offset on channel 1 between the zero reported by the software and zero measured at the probe tip.
You can see that offset on the screenshot to the right—the zero marker for channel 1 the green icon on the left is set exactly on the centre line, but the signal trace is half a division offset from that the probe tip was grounded. The oscilloscope also suffers from permanent ADC noise on the inputs, regardless of the sensitivity or other settings. You can see this noise on the green trace in the screenshot to the right. I admit that this is an unfair complaint as most digital oscilloscopes have this noise but their small screens generally do not show it.
I also found that with a USB oscilloscope you cannot just flick a switch to fire it up. You need to start the software, wait for it to load, make space on your screen, etc. Fortunately I always have a computer running on my workbench but many people do not and that would be an even greater impediment. And when I did that I found myself wishing for some of the neat features of a modern oscilloscope.
In the end I bought myself a proper digital oscilloscope—with knobs that I could twist, startup in a few seconds and a built in display the Rigol DS Series Oscilloscope.
Support is another negative for this device. When I first got this oscilloscope I kept checking their English website for updated software but nothing new was ever posted. When I last checked they had finally posted the update to their main website here , nine months after it was first available. Their support site is in Chinese but another support site here has limited support for English speakers.
I know that we cannot expect everyone in the world to speak English but if they want to be successful in English speaking markets they should provide better support in that language. On Sample Speed and Memory Depth. One issue that seems to be common amongst digital oscilloscope manufacturers is that they quote a sample speed and memory depth in their specifications but you cannot get both at the same time. What I would really like is to be able, without any caveats, to freeze a wave form and, if I wanted to, zoom in on a section by expanding the horizontal scaling by say times.
After all, this is what a digital oscilloscope with a large memory depth should be about. But, in practice, digital oscilloscopes like to capture to a small and fast memory and you must specially select their extended memory depth and then it will only work at a slow sampling rate.
