REVIEW - Rigol DS2072 - First Impressions of the DS2000 series from Rigol

[Altemir]

Hi guys.
Anyone know how much memory uses the DS2072 to estimate the FFT?
Thanks. 

Rigol said only 2048 dots

Not so bad.
Thank you very much.

Thank you very much.

If you don't need to do it real-time, you can do it externally with as many sample points as you want.

[Carrington]

Yes, using something like this:

@marmad: Is this your software? Because doesn't seems Matlab.

No, someone else - it's posted elsewhere in this forum: wfm_view

The only thing is that it requires the old WFM format (from the DS1000), but my upcoming version of RUU saves sample memory in old WFM format - so no problem

[Carrington]

I get it. 
But why did not you use LabView or CVI to implement your software? Many advanced graphics functions are already made.

I've been researching a bit. I don't know if anyone else has been wondering, who designed this equipment (DS2000 Series).
Well, this is all that I could find:

I figure that these people may be part of the team.

And labview is free software?

NO. 
LOL...

I'm waiting for the DS2000A with LA.

The Rigol MSO4000 has a sampling rate of 1GSPS for the LA. And I think that the DS1000D series LA has a sampling rate of 200MSPS.

I'm wondering if the DS2000A's LA will have a sampling rate of 500MSPS or 1GSPS.
Anyone know anything about it?

Thanks.

That would seem to be their logical next new-product announcement.  Perhaps mid-year.

The Rigol MSO4000 has a sampling rate of 1GSPS for the LA.  And I think that the DS1000D series LA has a sampling rate of 200MSPS.

That's correct.

I'm wondering if the DS2000A's LA will have a sampling rate of 500MSPS or 1GSPS.

Most likely 500 MSa/s.  Think about it.

Anyone know anything about it?

No, nothing at all.

Neither is extra BW, trigger and decoder options etc. for Rigol products...

Are there any rumours or confirmations about upcoming DS2000 series with built-in LA?
Will the LA have 8 channels or 16 channels? When is it expected? Details on launch date and model numbers? Pictures?

My speculations:
  - Upcoming DS2000 series with built-in LA? Yes, no doubt!
  - Model numbers: DS2072AD, DS2102AD, DS2202AD and DS2302AD.
  - LA 8 Channels at 1GSPS.
  - Launch in the EU, 6 months after it is launched in China.

Received two DS2202A this week for our company, including the offical options Deep Memory and Decode.
Thanks to this thread I was able to successfully update both devices to the latest firmware. I'm really happy with this new hardware version and the integrated 50R termination.
In return some old analog 20MHz HAMEG scopes were rejected, that's a fair deal

maybe you've found that out already: if you switch off while the screensaver is active, it'll also be active when you switch DSO back on (that means they actually store a "screensaver is active" value somewhere? really odd IMO

[Circlotron]

Not sure if anyone else has seen this yet - Each trace has a pointer at the edge of the screen identifying it as CH1 or CH2. With no signal in, CH2 trace lines up perfectly with CH2 pointer and so the offset reading of the trace (if any) corresponds with the trace position. For CH1 the pointer and the trace are offset by several pixels so the offset reading and the trace position are different. For example the pointer might be offset three divisions and the reading shows 3.00 volts offset but the trace is not directly over the graticule line. This is after the scope has calibrated itself after running about 6 hours. What's more, this offset of CH1 trace varies as you turn CH2 off and on.

Actually, on my DS2000 it's the opposite: with no input, CH2 is offset by a few pixels.

This is after the scope has calibrated itself after running about 6 hours. What's more, this offset of CH1 trace varies as you turn CH2 off and on.

I haven't calibrated my DSO for awhile, but the slight offset of CH2 does not change with CH1 being turned on and off. But as long as the DSO is aware of the offset (i.e. it's included in any measurements), I don't think it particularly matters. To check if there is an offset between the pointer and what the DSO perceives as ground, set the coupling to GND.

[marmad]

Here are my maximum offsets at the lowest voltage scale. You can see the slightly larger offset in CH2's stats:

EDIT: BTW, the channel pointer is supposed to point to ground - not the input signal level. If there is offset, the trace shouldn't line up with the pointer.

Okay.
I've taken a video and trying to compress it to a reasonable size to upload to youtube.

Righteo, here it is, 273MB compressed to 13MB for the sake of upload.
