Rigol DS2000 Hardware version 2.0
« on: August 01, 2013, 06:20:11 AM »
This is a DS2072 (or more a DS2202 now) with version 2.0 hardware.
Looks like they are going to use the empty spot in the version 1 hardware to make a D model with Logic Analyzer included, and while they were designing the new pcb the input channels got reworked too. Unfortunately it doesn't look like something you can populate at home...

Warning, large pictures!

Find the differences. The Game.   ;D

Apart from the obvious, noting:

  - Red: Removed, http://www.ti.com/lit/ds/symlink/lmh1980.pdf
    http://www.eevblog.com/forum/testgear/first-impressions-and-review-of-the-rigol-ds2072-ds2000-series-dso/msg266933/#msg266933

  - Blue: Add, I do not know what is, but I have an idea (A kind of comparator / level translator or a simple digital buffer).  :-//

  - There are also changes in the DC/DC power, it look better, but these changes will introduce less noise?
     What is behind, in the other side of the pcb? And I am not sure, but I think there are also changes in the PSU.  :-//

  - To the input stage has been added a 50 ohm terminator (and other relay).  :-+



Wow, they had designed it before the 2012/10/29.
LA connector is a PCI-E!



Thanks for the pictures to David L. Jones and PA0PBZ

PA0PBZ, you can select the 50 Ohm option?
Can you upload an image of the LA zone with more resolution?
I assume that this new version will have a new "line" for firmware.

Where is this (see DC-DC_B.jpg)?  Is it in the new PSU?
And where is this (see DC-DC_A.jpg)? In the other side of the pcb?

It seems that I write this post myself, LOL, but:

I've noticed that with the series DS2A1527XXXXX RIGOL not only changed the probes.

Serial: DS2A15270XXXX
Software version: 00.01.01.00.02 (latest I believe?)
Hardware version: 1.0.1.0.0

Leonard Tatzig: http://www.eevblog.com/forum/testgear/sniffing-the-rigol%27s-internal-i2c-bus/msg269946/#msg269946
Serial: DS2A1527XXXXX
Software version: 00.01.01
Hardware version: 2.0

DS2A1520xxxxx (Week 20, 2013) -> RP3300
DS2A1527xxxxx (Week 27, 2013) -> RP3300A



David's DS2202 is the 1.0 version, without further ado?
If so, them, we don't have images of the version 1.0.1.0.0. -> Someone like to volunteer?

PA0PBZ, you can select the 50 Ohm option?

No, it is on the screen in the CH menu but it is fixed at 1M. Not surprisingly because the firmware is the same as the version 1 hardware.

Can you upload an image of the LA zone with more resolution?

Yes, I will do that when I get home tonight. The scope is still in exploded view.  ;)

Thank you!
If you can take another picture of the PSU and the other side of the main board, would be great.  :-+

Maybe someone should give them a friendly poke and suggest they turn those heat sinks the right way up, now they are at it... :palm:

Although it looks like there is a 50 Ohm termination in the input channel now, it is not selectable in the menu, it is greyed out.

There are changes in the PSU to, but are minimal.
I wonder what's behind the mainboard, but surely there are others eight channels for the LA, at least the traces from the connector to what looks like a comparator.

well, if 50R is only available in MSO, then it could make sense to hack that DSO to MSO (even with no FPGA populated) to get it enabled.

I do not know, but at the moment it only has a stub at the input. But I don't think that it affects for a BW of 200 MHz.

Maybe, but the models are not on the market yet so there will be no firmware available, this one still runs on the hardware version 1 firmware. I wonder if you have the same non-functional 1M input button on that hardware...?

Yes, my HW version 1.0.1.0.0, is also fixed to 1M.

Now, this is my doubt:  Anyone know how many versions of HW exist until today's date?
And if this sequence of HW is correct (1.0 -> 1.0.1.0.0 -> 2.0), have the 1.0.1.0.0 version the internal 50 ohm termination too?



Okay I think I have the answer, just two HW version: 1.0.1.0.0 -> 2.0.
And I have the feeling that in the 2.0 Ver. they have improved the PSU and DC/DC parts.

After reviewing the new main board for RIGOL DS2000 (HW Ver. 2.0). I think than this M.B is valid for, DS2000-S, DS2000-D, and then too for a possible DS2000-[DS or SD or ?] (ie whit LA and Function Gen.).

Interesting, there is something about 50 Ohm and 1M ohm in the latest firmware, however on screen it shows the Ohm symbol, not the tekst 'Ohm'

Code: [Select]
........CH1....5
0ohm............
....0.........l.
....$...........

......1Mohm.....

This is a comparison between the two hardware versions.
Type of test: Noise floor.
Results for hardware ver. 1.0.1.0.0:

(1):

1. Oscilloscope turn on time ~ 30 minutes, and away from sources of interference.
2. No probe connected in any channel and, only CH1 on.
3. Setting: Full BW, Vector, 1mV/DIV (x1), DC,  Adquire=Normal, Men.=Auto, Persistence=inf., Base time=500us, Trigger level=0V.
4. Cursor on, mode Y, after five minutes of measurement with persistence=inf. set cursor to the maximum.


(2):

1. Oscilloscope turn on time ~ 30 minutes, and away from sources of interference.
2. No probe connected in any channel and only CH1 on.
3. Setting: Full BW, Vector, 1mV/DIV (x1), DC,  Adquire=Normal, Men.=Auto, Persistence=inf., Base time=2ns, Trigger level=between 500uV and 600uV
4. Cursor on, mode Y, after five minutes of measurement with persistence=inf. set cursor to the maximum.

In red, trigger level, find the worst case.

Hi Carrington, moving the trigger between 500 to 600 and I get very much the same results of my pic2.
