@Martin72: ask everything, but take into consideration, that there are far more skilled people in this thread, than me. But I will do my best.  ;)

Set the maximum sample rate and memory on the scope, then activate the LA.
Which memory/sample rate is then displayed?
Please provide a screenshot.
Thank you. ;)

If I am told, how to knit the sweater, then almost everything is possible.  :box: scheduled for tomorrow.

Is that so? According to the data sheets, both the DHO900 and MHO98 have the same power supply specification.

Unfortunately, the data sheets only specify the power supply, not the power consumption... Very useful. :P
Be that as it may, according to the data sheets stored at Batronix, the power supply for the DHO900 series has 48W of power, while that for the MHO900 series has 70W.

And the MHO98 come with a 100W Power supply drawing 60W idle.

Actually, the datasheets for the MHO98 and MHO900 (*) I downloaded both specify a 70W "Power", but also a "Power Voltage" of 20V / 5A.
Anyway, I don't doubt that the MH98 draws more current than an DHO900, but the fan is substantially larger, so the fan noise should at least be different.

[EDIT]
(*) Ah, sorry, I thought I downloaded a DHO900 datasheet but downloaded an MHO900 datasheet instead which has the same power supply specification as the MHO98 of course.
Still, these datasheets specify both, 70W ("Power") and 100W ("Power Voltage") for the supply. Not the best datasheets anyway.

I may need to qualify that statement regarding the data sheet.
At least for the MHO series, they (rigol) have specified the power consumption, albeit in a somewhat confusing manner.
The power supply for all MHO900/98 models is specified as 100W (20V, 5A), while the power consumption is specified as 70W.
However, this is not stated explicitly.

I played around a bit with the settings there are strange dependencies switching the Mem Depth, but this is it with max values.

Rigol has still to do some work on the firmware.

- The IP-address is not shown - it is connected, but still displays 0:0:0:0:0
- The timezone is fixed to China. Connecting it to the network reverts the manually chosen time. But as I remember, we did have a similar annoyancy with Siglent...
- More probably to discover

My MHO98 just arrived  :popcorn:

It got a special number FF

It less blingbling than on the pictures  :)

WIFI connected, there is a keyboard on the screen, no need for external keyboard

Mouse work but click does not work when touchscreen is deactivated  :palm:

Firmware version 1.0

Somes options are "limit" ,check picture

There is a document to complete to unlock the "limit"

Bluetooth is included

Yes, there are bugs in all equipment. Siglent, Keysight, R&S. And they get fixed there. With Rigol it is a bit more stochastic. Hope dies last..

Haven't they included codes for those 'limit' options?
It looks to me that even those options should be included (for ever).

They are not included, but should become included following the registration on that document.
I did it yesterday, but no reaction yet from Rigol - not even a confirmation mail.

There is a document to complete, I just did it and send it.

According the document something should come by email, maybe a code to enter in an hidden place or simply a gel file to install ...
Or maybe they wil activate it by internet  :wtf:

FTFY
SDS2000X Plus got a FW and OS update to fix it.
Never experienced it personally but helped a few to correct it.

The more interesting thing would have been how the sampling rate and memory change when you activate 1,2,3,4 analog channels with and without the LA.
I.e. I suspect the LA will lower the sampling rate and memory just as if an additional analog channel was activated.

Batronix stopped accepting orders for MHO98 and the product disappeared from the product list.

Interesting. So unlike the DHO900, switching on the LA seems to reduce neither the sampling rate nor the memory depth.
This would mean that the LA is independent. Strange though that Rigol doesn't feel the need to specify any of this in their datasheets.

Talk to the people who sold it to you, they're probably supposed to email you the codes.

These things are tempting... but I know I don't need one. Must resist...  :scared:

Batronix lists the MHO98 as "no longer available". I guess they sold their entire quota.

This is part of the "dependencies" i encountered by switching values like memory depth manually.
But interesting: you can switch on LA without the PLA2216 - something which is not possible on a 924S, where you only get a "not connected" error.

61W minimum consumption you'll need a respectable (expensive) powerbank to be able to use it for 3 hours.

But this is a nice strategy to obtain funds 1998x1350€ =  :-DD :-DD :-  :-DD

You are right, it draws quite a bit. Question is, do I need to carry it with me for my "outdoor activities" or do I use my XEast (or Fnirsi...) portable with me.
