I have purchased a HP/Agilent 54111D. I need some help to understand. I apologize in advance for my ignorance and this may be the wrong forum to post. Please point me to the right forum.
Let me ask a basic question on DSO specs. I see oscilloscopes have come a long ways offering performance and features at a fraction of the price of 25 year old equipment.
I am finding Agilent and Tektronics and BKPrecision scopes to offer 500 MHz capability, but at a sampling rate much higher than the 1Gs/s of the 54111D. Why the need for these much higher sampling rates to accomplish the 500 Mhz bandwidth? I find 200 Mhz scopes sampling at 2Gs/s. There are others with higher sampling rates. Also there is a difference between sing-shot and repetitive bandwidth. When a scope is specified to have 200 MHz, is this single shot or repetitive bandwidth?
The effective resolution of my scope is 6-bits to 8-bits. This is frequency dependent. There are scopes that provide a claimed nominal resolution of 8-bits and even a higher effective resolution, perhaps up to 12-bits. This must also be frequency dependent, correct?
Any help would be appreciated. And if you only can refer me to another document or forum on the Internet please do.
