Key points: 
Display type: Display type includes Vector and Dot. In vectors type, oscilloscope 
connects dots through digital interpolation including both linearity and sin(x)/x. 
Sin(x)/x interpolation is suitable for Real-time sampling and will be more effective at 
50ns or faster time base. 
Refresh rate: It is an important performance of digital oscilloscopes. It means the 
number of display refreshing per second and it will affect the ability to observe 
signal.
