New Rigol DS1054Z oscilloscope

That's true. But you also must know that a ground plane on a PCB isn't the same as an earth connection.
That occours on a ground plane due to copper resistence and due to high frequencies (you don't give time to the copper potential balances).

The analogy is still valid; the speed of light and distance are the relevant parameters. As I explicitly stated, with electrical distribution networks the relevant frequencies are lower. Obviously you realise that lower frequencies imply longer time periods.

In a thunderstorm you don't have that high currents for too long, I think...

True, but that doesn't affect the point under discussion.

But I think that a lightning strike only affects a small portion of the earth, and not the entire earth potential...

And how, exactly, are you going to measure "the entire earth potential"? Your answer should take account of the speed of light.

You really, really should have a look at the precautions taken in industrial systems to take account of differing "earth" potentials.

You don't need to measure the entire earth potential. You just need to try to "send" the lightning strike to another earth connection than the one used by you, no?

I don't know almost anything of the industrial protection systems and how they deppend on earth connections, what I know is that the earth plane created in each build (house, factory, High voltage line supports, whatever) has a lot of testing in order to reach a regulated resistance value (in the order of mOhm). With this I just want to make clear that an earth point is virtually isolated from another point few meter away. If you just put a wire on the ground you won't have (it just won't work, believe me) an earth point.

And there we have the source of your statements, and your ignoring several examples (e.g. monopole antennas).

You partially understand how domestic 50Hz electrical systems work in a house.
You are (incorrectly) generalising that to non-domestic systems.
You are (incorrectly) generalising that to >>50Hz systems.
You are (incorrectly) generalising that to physically large systems.

I'm talking about electrical power lines. They don't serve only houses, their earth plane is independent of the use that power will have.
I didn't spoke about >>50Hz systems. I did generalize my statements but I know that specific niches have their specific regulations.

But what does that have to do with 'scopes ground? Why this discussion started? Also, I don't understand why you're so agressive and why are you just "spiting" statements and don't be more specific...

Hello. Is it possible to connect ds1054z with lan cable to pc and see fft from matlab?

Thanks for the reply but I saw this before. There is no driver for ds1054z in any of two categories.

I think that page is just old. The command interface on the DS1054Z is the same as all the other Rigol models in the list.

FWIW: The official DS1054Z programming manual has a whole chapter on how to use a one with MATLAB. Section 3-7 even gives example code to grab some data from a DS1054Z and generate an FFT.

Wow! Thank you. This is exactly what I search!

Hello, i have now upgradet to the latest firmware too (i know i am late, i was quite busy). I think i found a minor bug. When i am in fft mode and have the cursors active in the fft window, the cursor jump to the timebase window as soon as i press "measure" -> "clear" -> delete or recover any item. The curser source still says "Math", which is incorrect. You have to rechoose "Math" to get it back in the right window.
Another thing which is not really a bug but funny somehow: You can shift the cursor to negative frequencies. It made me giggle a bit, is this typical on oscilloscope with fft/spectrum analyzers?

Hello. The normal is 1 or 2 boxes for a brand new ds1054z?

[canibalimao]

Hello. The normal is 1 or 2 boxes for a brand new ds1054z?

I think that Rigol initially sent it in 2 boxes to help you sending it back if something occours, but now I don't know if they still send it that way.
I got mine about 6 months ago from Telonic and it came in just one box.

Hello. The normal is 1 or 2 boxes for a brand new ds1054z?

I bought my DS1054Z on taobao one month ago, the normal packing is 2 boxes.

2

[tautech]

Normal delivery from the factory is double boxed in either 1, 2 or 4 units/box.
Receive a 2 or 4 scope order in a large box, then break it down then each unit will be in single boxes.

Either is acceptable packaging.

[raptor1956]

I ordered mine a few weeks ago from Amazon and it arrived in an Amazon outer box followed by two more Rigol boxes inside that -- so three altogether...

Hello. The normal is 1 or 2 boxes for a brand new ds1054z?

I ordered mine from TEquipment on Amazon (not Prime or FBA), and it came in one box.   

[Karel]

Mine arrived also double boxed.
At work, almost every instrument we bought arrived double boxed as well.

[thomastheo]

I bought mine from Batronix in Germany. It was shipped in a single box.

One thing I don't think I saw mentioned: how is the UI responsiveness with 04.04.00.07 compared with 04.03.01.05 (04.03.SP1)?  I've intentionally kept my scope on 04.03.01.05 in order to avoid the issues with SP2 (especially the UI issues), but if the UI responsiveness is the same for both 04.04 and 04.03.SP1 then it sounds like there's little reason to remain on 04.03.SP1.

[nanofrog]

FWIW, mine came in a double box directly from TEquipment.

Be carefull. My ds1054z fw is 04.03.SP1 and i don't have rms bug, like people with last two versions of firmware. So, for full screen X-Y mode, for me is not worthy to update to latest firmware.

Hello everyone.
Anyone noticed Math->Filter bug? With the recent version of FW (probably with former version too) signal at the output of Math/Filter is shifted (delayed), and starts with "delay" - left side of the filtered signal's plot is "deleted", and the "deleted" interval is about equal to the time of the "delay".
BTW, RIGOL used non-casual filtering algorithm, and its response may look little strange in some situations.

[alsetalokin4017]

Well, I've certainly noticed it. I can't remember if it did this on the previous firmware or not, but I'm sure we will hear from people who haven't "upgraded" yet who can test it for us.

The Filter trace always starts 1.5 divisions to the right of the left edge of the graticule area, no matter what timebase setting. The trace itself seems to lag about 1/2 division or so, more or less, depending on timebase setting.



Oh... and boxes:
First one, from TEquipment, two boxes
Second one, from TEquipment, one box
Third one, from Rigol USA, one box, that had been sent to some other state, was returned to Rigol, then sent to me. (Old shipping labels still on it.)

[Sredni]

I have no Math Filter in my ooooold version (if it's there I missed it), but the lag and missing part lead me to think they are doing some convolution mumbo jumbo and need a number of points before producing a result and they did not care to shift the result back (probably because, since all computations appears to be done on visualized data, they would miss the same part at the end).

Just guessing.

[bitseeker]

I get the same filter delay on 04.03.01.05. Unfortunately, I can't save a screenshot right now because the scope doesn't like my made-in-China thumb drive. Irony?

All the buttons stop functioning after inserting the drive. It's a 2GB formatted using FAT32 and I tried 1K, 2K and 4K cluster sizes. Oh, well. I'll have to find the one I used for firmware updates before. That one worked.

Anyway, the delay looks the same as what IAmBack posted.
