The Rigol DS6104 oscilloscope I purchased with my start-up arrived today. It
has no touch screen, but the price is 1/3 of those from big companies. The CD
attached contains the software and drivers to operate the oscilloscope through
USB or LAN. The readme file tells you to download USB driver from NI first.
But it is misleading. One just need to extract files from \SOFTWARE\Ultra Sigma(PC)Installer.rar using 7z, run setup.exe and all drivers from NI will be installed automatically.
The stand-alone bench oscilloscope in practice is better than cheap USB ones.
The later normally has very poor front-end electronics, low sampling rate and narrow bandwidth. Picotech provides high-end USB oscilloscopes. Given the same price, USB ones provides higher precision, more memory, more functions and better data logging, but less bandwidth and sampling rate than bench oscilloscopes.
