Dear Dave aficionado's
I have a very few understanding of electronics and about oscilloscopes. I am an Arduino person and i start to play with electronics not a long time ago. The best way to learn something is to start with a hard project to achieve - is my way to learn things. I want to analyse and i want to process DVB-ASI streams. There has a good opportunity came up in my region to buy an Oscilloscope with a reasonable price.
Therefore i do not have enough time to dig around and make a research for an answer of my own question. Key Features of the oscilloscope which i would like to buy is listed below. My question is if i can examine a full DVB-ASI stream with this oscilloscope? If it is not capable; what should be the minimum Oscilloscope characteristics for DVB-ASI examination?
"DVB-ASI is carried at a 270 Mbps line rate. The 270 Mbps bit-rate on the link is derived from a 27 MHz byte clock multiplied by 10 bits. The carrier frequency of a DVB/ASI signal is 270 MHz. The maximum effective bit rate is 214 Mbit/s."
I just can not make a calculation and a meaningful conclusion from the information above - what kind of an equipment is sufficient to visualize this stream. How much bandwidth do i need, which sampling rate is enough, how much sampling memory is sufficient etc.
I just presume that 500MHz bandwidth should be the minimum bandwidth because of the 270 MHz carrier frequency, and presume that 1GS/s Sample Rate should be enough because of the 214 Mbit/s payload and i do not have any ideas how much do "Recording Length of 50,000 points memory" play a role in my scenario?
All of my assumptions might be incorrect because i am a beginner and i need guidance!
Key Features of the oscilloscope which i would like to buy is listed below.
TEKTRONIX TDS 540A 500MHz Digital Oscilloscope
Key Features:
----------------------------------
500 MHz Bandwidth
1 GS/s Sample Rate
4 Input Channels
Record Length to 50,000 points
8-Bit Vertical Resolution
Thanks for your time!
And Dave you are one of that Mega's who can change the world
