new (last month) 1054Z with all upgrades and SP4 firmware.
When viewing a PWM square wave -
single channel, AC coupled, triggered @ ~ 50%, Vert = 100mv/, waveform centered.
As the pulse width of the signal is changed, the position of the waveform on the screen changes.
50% - waveform is centered
60% - waveform moved down 50mv
70% - waveform moves down another 50mv
40% - waveform moves up 50mv
30% waveform moves up another 50mv

no settings changes on the scope, it is AC coupled, so why does it move?

It moves exactly because it is AC coupled. The average voltage of your signal changes as you vary the PWM duty cycle. And AC coupling puts this average voltage at the center of the scale.

That is one of the reasons I like the peak-to-peak automatic triggering modes in old Tektronix oscilloscopes; the trigger point does not change as the duty cycle changes but it still tracks level changes.

new (last month) 1054Z with all upgrades and SP4 firmware.
When viewing the cal signal - as I change the time base, the displayed rise time changes.
The signal does not change so why does the displayed rise time change?

Because all calculations on a DS1054Z are done using the "on screen" data. You get most accurate numbers when you zoom in.

Thanks, so for sample shown the 3.00µs is the closest, except that is most affected by the sample rate so it varies a lot
If the sample rate is 1Gs/S, what variation should I expect? It seems like it varies more that the sample rate would indicate. What else affects it?

It's nothing to do with the sample rate.

It's the pixels on screen, nothing else.

Hello i have few questions about rigol ds1054z

1. My rigol has 04.04.03 firmware i patched it in past to enable all features including 100mhz bandwitch , now i wants to update firmware to latest available and i dont know how? , should i delete feature hack after update it to latest firmware and patch again to enable all features ?

2. There are few pc-apps to communicate with rigol by using pc and store captured data but this isnt enough for my projects , lets say i need to store 50 - 100 captured traces of similiar signal each trace individually triggered
This feature is working by using function called waveform record , it can store many traces by recording and later is possibly to playing trace by trace/next trace etc. but these waveforms are recorded and stored inside rigol memory
So my question is about is possibly to download somehow from rigol all this recorded waveforms to PC after ? not live but after all recordings done
Thanks

No need to remove keys. Just roll the update - licenses will be carried over. The "hacked" keys are official keys due to bad implementation of key encryption. :)

You can simply write the recorded waveforms to a USB memory stick via the front USB port.

1. thanks
2. I dont see that option in RIGOL DS1054Z i can save only one currently displayed  waveform to usb pendrive , but in waveform record menu is possibly only to record/play+repeat steps etc.. but option to copy all recorded waveforms to pc or usb is not available or did i miss something ?
Ive checked also rigol scpi commands and i dont see any commands related to dump waveform storage buffer to pc

https://www.eevblog.com/forum/testgear/rigol-ds1000z-and-mso1000z-exporting-waveform-to-computer/
it seems nobody is still understanding me :)
but ok ill try to explain again deeply

all this apps available for connect to rigol are able to download printscreen from rigol or saved waveform whatever which is available to load via rigol menu for display too

whats i wanna achieve there is to download all recorded traces which arent available for download to usb pendrive
there is one function in rigol called waveform recording option you can do long recordings trace next trace next trace etc.. later you can display/load them to rigol screen or delete after but there is no way to download them from rigol
the problem is i need record many traces as fast as possibly and download them
offcourse i can do one trace download it via pc app and do second trace and repeat download but this would be nightmare if so many traces like 50 - 100 will needed to download

I understand that DSRemote can download full waveform data, but have not used it myself:

I can't recall such a feature in various 1054z related software.
Check the programming guide, it may be possble to do by scpi command.
Short pieces, high value, small period, huge amount, long delay.

@ebastler thanks i will check dsremote soon when i have access to linux system

well... looked into scpi commands in short but i dont see any commands related to my case

btw. have another question i think there is just one rigol osciloscope model who has external reference clock input (this function and port doesnt exist in DS1000 series)
with this function is possibly to synchronise oscilloscope with device clock to measure only on clock edges do anybody know is possibly somehow to mod DS1000 oscilloscopes to add this functionality ?

It's missing from many (most?) 4-channel 'scopes. The trick is to use one of the 4 channels instead.

Using one of the channels (no need to display it) would do as a replacement for an external trigger, but I think lfldp was asking for an external reference clock, to be used in place of the internal oscillator e.g. to synchronize several instruments or for better time precision.
That kind of input is generally not available on cheap scopes.

i reply to few posts
thanks for help there
 @PeDre i understand about you wants to release something which i missed but only for currently used instruments by you (but i can do it myself too by adapting SCPI commands right?)

@Fungus offcourse you can do it like that but you get jitter you dont get clean trace 
@newbrain thats right this is exactly about whats i mentioned there whether the ext reference input clock is available in oscilloscope you can reduce needed sampling rate alot and perhaps thats why oscilloscope manufacturers dont installing that kind of options in low budget devices
anyways few months ago i read in google somwhere about there exist some kind of modiffications for certain oscilloscope manufactures to handle ext ref
well maybe after few years somebody would intend to reverse rigol firmware and to add some functions :) or maybe i do it myself it need access to fpga bitstream and could be big problem to add this feature do i have right ?

I have a DS1000Z and a self-programmed program. I can extend the program so that you can save the records from memory. You only have to specify the required data format. The program does not store any data at the moment.

Peter
ok
but the required data format by me or data format stored by rigol after recording done ?
if required data format by me i think is standard .wfm waveform , i think recording options store traces in same format

I did not double check if Rigol is keeping true to the initial specs, but AFAIK the .wfm waveform file type has been developed by Tektronix and all the specifications are to be found here: https://download.tek.com/manual/Waveform-File-Format-Manual-077022011.pdf

There is a data-from-wfm wfm to csv converter (and C library) by Rigol https://rigol.com/Support/SoftDownload/5 as well as some "waveform read" C# and matlab examples that can maybe shed some light on Rigol's wfm file structure.

There is already a firmware version "DS1000Zver_04.04.04.03.zip" available from Rigol.
Downloaded it yesterday and upgraded my instrument already without a problem. Unfortunately I forgot, where I got that update from, but I think it had that infamous entry form in front: I entered some pretty name(s), "any" serial no  :) and the instrument model and => voila... got the latest update immediately in return: Link https://beyondmeasure.rigoltech.com/acton/form/1579/0025:d-0005/0/-/-/-/-/index.htm

By the way, all new DS1000Z oscilloscopes come with all options enabled now for "free". No more "illegal" hacking then...
