No manufacturer nor distributor will send you the main board ("central plate" ?) for you to fix it yourself, period.
So stop dreaming.
Just ask Keysight, Tektronix, Siglent and etc, none will allow you to do that, so its not only Rigol.
You must send back the whole oscilloscope back to Tequipment or Rigol, which is we already know that is not possible as the shipping price it self maybe more than the price of the oscilloscope.
Just want you to realize that your rant about Rigol & Tequipment is pointless, it will happened exactly the same again if you buy Keysight, Tektronix or Siglent across border.
We have few Siglent distributors here in this forum, just ask them "publicly" not in private message, if the product is broken when bought cross border, will they send you the main board for you to fix it your self ? I don't think so.
¿Ningún fabricante ni distribuidor le enviará la placa principal ("central plate"?) Para que la solucione usted mismo, punto.
Así que deja de soñar.
Solo pregúntale a Keysight, Tektronix, Siglent y etc., ninguno te permitirá hacer eso, así que no es solo Rigol.
Debe devolver todo el osciloscopio a Tequipment o Rigol, que ya sabemos que no es posible, ya que el precio de envío puede ser superior al precio del osciloscopio.
Solo quiero que se dé cuenta de que su diatriba sobre Rigol & Tequipment no tiene sentido, volverá a suceder exactamente lo mismo si compra Keysight, Tektronix o Siglent al otro lado de la frontera.
Tenemos pocos distribuidores de Siglent aquí en este foro, solo pregúnteles "públicamente" no en un mensaje privado, si el producto se rompe cuando se compra a través de la frontera, ¿le enviarán el tablero principal para que lo arregle usted mismo? No lo creo.
and 5º if you are not going to contribute ideas of possible failure or how to look for it, and a problem that can make you leave it like this, then do not think about things that are not relevant.

Yes, I will stop, as I give up too, good luck on your quest.
Sí, me detendré, ya que también me rindo, buena suerte en tu búsqueda.
it is when the equipment cools, that it happens, also in different measures it happens in the four channels.
The compensation is about edges only, thus the rise and fall times of the 1kHz has to drift away.. Less likely I think..
Ok, you compensated the TEK probes when Rigol was warm.
When you use TEK probes with Rigol, you see bad compensation when Rigol is cold.
After 10 minutes, when Rigol warms up, the TEK probes show good compensation.
Correct?
No manufacturer nor distributor will send you the main board ("central plate" ?) for you to fix it yourself, period.
This DaveJ schematics of the Rigol's front end shows the capacitors under doubt.
Based on the info above, imho, Rigol used a capacitor(s) with a higher temperature coef as allowed in the schematics below..
PS: I would rule out the temperature drifts in the related analog circuitry (opamps/dac, operational points of transistors, etc) as the issues Adrian shows are only signal edge related (AC stuff).
He is not indicating the 1kHz ref signal moves up/down or its amplitude is higher/lower.
No manufacturer nor distributor will send you the main board ("central plate" ?) for you to fix it yourself, period.You are completely wrong, I received main boards from OWON 2-3 years ago with a video on how to open the scope and make the repair myself. It is very cost efficient for manufacturers to do it.
Returning to the subject, the use with that failure, in time could become a disaster?
The attenuator network (with the capacitors in Q) is used for 500mV..10V/div ranges people say.
@Adrian - is it possible to check your issue when you set the vertical range (while watching the calibration signal quality) outside that range?
For example:
1. 10x Probes (Rigol or TEK) compensated when Rigol is warm
2. with cold Rigol watch the signal below in an available range below 500mV/div or above 10V/div
If the signal with cold Rigol will be compensated properly, than the issue comes from the attenuator network (see the schematics above).
Thank you for giving me the reason to my request both to rigol and to tequipment that is in my opinion the one that would have to intermediate with rigol, since it has sold more than 1000 rigol ds1054z, according to their statistics and have more than 500 stock.
there are companies and others are business projects (rigol). The sad thing is that I fell for a bad publicity made by certain people that is not worth mentioning.
There is one thing that I forget to document.
When I turn on the equipment with the X10 probes, after a few hours, these are decompensated.
above 10v decreases, almost imperceptible, below 500mv decompensation increases.
in spanish
por encima de los 10v disminuye, casi impersectible, por debajo de 500mv aumenta la descompensacion.
There is one thing that I forget to document.
When I turn on the equipment with the X10 probes, after a few hours, these are decompensated.
but if I move the key from X10 to 1, the defect is automatically corrected, without specifying to the oscilloscope that I have changed the key of the probe. CH1> Probe> X1.
Does it automatically detect the change?
in spanish
hay una cosa que me olvide de documentar.
cuando enciendo el equipo con las sondas X10, despues de unas horas, estas se muestran descompensadas.
pero si muevo la tecla de X10 a 1, automaticamente se corrige el defecto, sin especificarle al osciloscopio de que he cambiado la tecla de la sonda. CH1>Probe>X1.
¿este detecta automaticmente el cambio?
