Have you worked that out yet ?

This DSO is PC based and it is normal to have audio capabilities on a PC main board.

It is normal indeed. What I'm asking though is in which scenario an o'scope would need an audio I/O.

Martin72:
You can't get a mainboard without these connectors.
They are simply there and are not used.

There are applications imaginable.

A microphone could be used for audio notes accompanying screenshots for documentation purposes or even voice control for the instrument.

Headphones on the other hand can be used with each spectrum analyzer that has demodulation capabilities.

Maybe we'll see some of the above features in the future...

Very good ... a starting point for compare  ::)

>> The reference clock is a square wave form

Also 50E load enabled? And may tell what brand do you use?

Does SE-120 means WavePro HDO404 HD ??

>> SE-120 wavepro jitter kit

Do you get equal Histogram on each channels as Ch2, Ch3, Ch4 ??

>> SE-120 wavepro resjit histogram

May have to check its a part of the new SDA III or JitKit

As Teledyne JitterKit Paper, recommended to use 10 Wave Cycles ... and you use may 200 Cycles: Any reason for this?
 
Or do you have your own guidelines :D

Yes 50Ohm impedance which is really essential for square waveforms where as sinewave it's much, much less critical imho.

I used full SDA linq with the new 10.5 FW and it's very very close on all channels. The jitkit is just a basic look but an accurate one in fairness.

In the new year the jitkit will be superceded by Clock xpert which will separate certain aspects of the SDA which will concentrate more on higher spec pcie/usb4/6G/ high speed serial data formats.

This I suspect is aimed at the new Wavemaster HD

Clock expert will include indepth eye analysis full jitter suite plus a new phase noise section incorporated.

I also have a Holzworth phase noise analyser and a UXA 50Ghz unit with phase noise app. So I have that aspect of measurement covered I feel.  Although Aaronia have some interesting products in the offing as well next year.

The label SE-120 refers to the clock's model number

Lecroys whitepapers are guidelines and each user I feel will adapt the settings for their own applications.

Our UK Lecroy reps are always on the lookout for tips and tricks to improve measurement ways and to reduce all operator error and refining the processes. Its a two way street.

I find the eye view & dual spectrum analyser option used in conjuction with a couple of RP4060 rail probes to view the clocks supplies rf noise sitting on the rails. On top of that a RTA with near field probes looking at clock radiated rf and board layouts can tell you a great deal inho
