How to measure jitter? Step 1 - get a $20k oscilloscope which has a Jitter button on it Step 2 - measure jitter

Believe this scope is 150K plus.

Hey can you also walk us through how to measure jitter “without” a built-in jitter analysis tool on scopes?

she can't...she hired to just press buttons and read a script. Keysight unfortunately doesn't market to adults.

What was the purpose of the pll in regards to measuring the jitter? Hasn’t it made your signal appear better than it is? Or is it a tool to help us improve our designs?

What sort of probe is needed for this, and what else is needed to keep in mind? any application notes for that ?
@KeysightLabs2 жыл бұрын
We have a lot of info about probing on this channel and on the Keysight web pages around probing. The scope doesn't really care what probe you are using for jitter, but you want to make sure you're using a probe that can handle your signal's parameters (Voltage, bandwidth, etc.)

Excellent video... For jitter measurements should we use active or passive scope probes. Which do you recommend? Thanks
@KeysightLabs3 жыл бұрын
It depends what other factors you have to consider. Generally active probes are used because of the bandwidth of the signals being tested.

Question: "20KHz TIE sinusoidal modulation has been eliminated by setting clock recovery PLL bandwidth to 200KHz." Is this a wrong statement. I think the 20KHz are well within the 200KHz PLL bandwidth and the 20KHz TIE will pass through PLL without attenuation. Please advise.
@ricardonunes67245 жыл бұрын
The loop bandwidth of the PLL used to extract the clock from the data signal is higher than the 20 kHz. This means that the clock frequency/phase will follow the 20 kHz jitter and the receiver will not be impacted by that jitter.

@@ricardonunes6724 can you elaborate a little? I am also a little confused... with a low-pass of 200kHz, aren't we letting the 20kHz modulated sine wave through?
@ricardonunes67243 жыл бұрын
@@acadacabra2010 From what I understood, the oscilloscope is using a PLL to generate a clock based on the data signal, which has the 20 kHz deterministic jitter on it. Then, it locks to that clock. As the loop bandwidth of the clock recovery PLL is larger than the deterministic jitter frequency, the recovered clock will also have this jitter. As the jitter appears now both on the recovered clock and on the data, a receiver which is locked to the recovered clock will not see the jitter. If the loop bandwidth of the clock recovery PLL was lower than the deterministic jitter frequency, the recovered clock would not have the jitter and a receiver locked to the clock would still see the jitter.
@邵竹元3 жыл бұрын
@@ricardonunes6724 In the case with PLL, if the recovered clock also have this jitter, is the oscilloscope making an inaccurate measurement of eye diagram? The eye diagram is supposed to reveal all defects of the DUT, instead of locking on to something wrong, right?

Came here because of ElectroBOOM, stayed for the useful and well-produced content. This video is a great introduction to jitter, and it filled in some gaps for me. Now I know why I need a better scope. :) Minor quibble: I believe "Gaussian" is pronounced "gouse-ian", not "gaws-ian."

OMG you guys are hell bent on over-complicating stuff, abbreviating unnecessarily long terms and pimping those scopes. "The bi-flodial crembrulators or BFC are simulated with the temponic krempt digileets or TKD. They are the same color as the omobaric sinusoidal rabbit ayenus flap or OSRAF" Ok. Shit changes time when it is supposed to be there. The scope shows it. Look at the pretty colors. End.
