That's the same $899 the DHO1074 has been selling for since February. Looks like the promotion will extend through July. It's $100 off, but nowhere near the deal that BF was ($400 off).

I am working with the Rigol DHO 1072 for 2 weeks now and it is finally the scope I was looking for many years now. I need it for audio stuff that means low noise, low SFDR, high vertical resolution but not so much bandwidth.

Pros Presale

* Very well specified
* Because many features from the DHO4000 series: very well shielded (information thanks to EEVBLOG teardown) and 1.5 ppm clock precision
* 10 MHz reference input / output
* Averaging and High Res mode in acquisition not just math
* screen resolution 1280×800
* Good visual representation of analog waveforms
* fast and reliable datatransfer for scripting (python / pyvisa)
* Window docking
* pricing ok Pros from Testing for 2 Weeks now (latest firmware release xxx.12)

* Very good general user experience:
* Really sensitve well shielded instrument with low noise and good SFDR. I finally can see all this mud that my function generator is creating.
* Ergonomic workflow including FFT(!).
* Many small but useful features that make this a great scope e.g. Option windows can be left open during measurement because they can be set to transparent background.
* Low SFDR / noise
* 16 Bit High Res mode @25 MHz bandwidth (with full 2 GSa/s sample rate) !!!
* 14 Bit High Res with 50 MHz bandwidth.
* With the usual bandwith reduction of factor 4 per bit this would be 3.125 MHz not 25 MHz in 16 Bit mode. So it looks like the High Res Filter for 16 Bit doesn't reduce the corner frequency directly but the 14 Bit filter is applied for a second time so that the filter attenuation is larger instead (not sure)?
* Actual good visual representation of analog waveforms as expected.
* 1 MSa FFT works fine. As always the FFT has to be set up approriatly by the user to get the optimal results.
* Remote interface works fine using python scripting / pyvisa. There is one issue: see cons.
Cons from Testing

* Encoders

* in this blog it was reported that encoders sometimes can lose a step. It was speculated if this is a mechanical, software, asic, ... issue: It's mechanical. I have it at the horizontal encoder. But with light side pressure the problem is gone. So it's no showstopper for me but nevertheless Rigol should use other encoders in future versions.


* When measurement is stopped and memory setting is changed then after next measurement the user interface should show the new samplerate. Works with autotrigger but not with single trigger. The refresh is finally triggered when e.g. the horizontal time base is changed. Not a showstopper because just a GUI problem and a workaround exists. When using the remote interface the correct value is provided. But Rigol should fix it with a firmware release.
* XY

* As shown here for the DHO900 33:35 the grid in xy mode is not quadratic. XY is a visual tool so sin/cos with equal amp should be a circle. Nevertheless the scale values are correct but Rigol should change that with a firmware update.
* When getting large waveforms from the scope with scripting/python/pyvisa I need an additional delay of about 200 msec to get the correct waveform. *WAI, *OPC?, *OPC + polling event registers, ... don't provide the required handshaking. Rigol should fix that in a future firmware release.
* FFT cannot use math channels as source. That issue was discussed in this BLOG. It cannot. I understand that this is a performance issue but a slow FFT when using a math channel is better than none at all. Rigol should change that with a firmware release. Siglent Comparison (SDS1000 HD) (Only Presales no Testing)

* Showstopper for me was that Averaging and High Res ("ERES") is just available as math channels. For audio stuff High Res is the most important mode. And a learned from experience that Rigol has 16 Bit@bandwidth of 25 MHz with smarter filter than just moving average / decimation.

* I heard that for SDS2000 HD series this is planned to be changed with a firmware release but I didn't want to bet on a firmware release for the SDS1000 HD series. When this would be included in a future firmware release it would actually be a game changer.
* Spec not as good as the Rigol DHO 1000 datasheet. E.g. I didn't find the clock precision. My fault?
* SDS1000 HD has lower screen resolution than Rigol DHO 1000 series. Hm ... it's a 12 bit scope ...
* SDS1000 has better math (formula editor, ...) but Rigol math is ok for me because the math channels can be chained (exception FFT :( ). More complicated stuff has to be done with scripting anyway.Rigol DHO800 comparison (Only Presales no testing)

* Thanks to the EEVBLOG teardown I have learned that the DHO 800 internal shielding is not what I expect from a sensitive measurement istrument. DHO1000 quite the opposite. Looks rock solid and instrument performance shows that.
* DHO 800 screen too small for a touchscreen with docking windows.

Installed on my DHO1074 without any issue. All options still active. I just had to do the fan speed hack again.
