I haven't usb 3.0 on my lab PC or laptop.
But it strange that this happens at the two PCs many times.
I will wait to have feedback and from other members...perhaps I win the joker!

Mine installed without any problems on a USB 2 port. I'd be suspicious of the USB cable. I bought a new, more expensive cable before I attempted to install the RTX and related software. I'm on Win7

Thank you Jens for this. What if there is no Windows computer available? The RTX6001 is not locked in to a particular operating system or software package, so this Windows-only solution is not right. What are the alternatives?
I guess the firmware upgrade takes care of the inverted polarity thing. Anything other changes with the new firmware?
Hi Jens,
Definitely interested in getting a set of shields!
My firmware upgrade is failing with an error
"TUSBAUDIO_GetDfuStatus: Function failed with error code 0xEE000003."
I was referring to my original installation before. I have reset the USB connection 3 times now and cycled power on the RTX 6001 twice. I was using the unit just before trying the firmware update. Hopefully that helps Jens.
Again, Win7 running on an i5 quad core cpu in a Lenovo Thinkcentre tower case. M-92 I think.

Mine problem was resolved.
I tried many installation with different usb ports, cables, restarts and so on.
At a lucky trial this operated well.

The reference to the Xcore discussion reminded me that we did have a problem with firmware update with a particular FW version. I don't think that V1.10 had the problem, but try to turn on the power when doing the update if you haven't already done so.
Loaded firmware just fine with win7
What are your objectives with the shields?
if you are looking for lower 60 hz incursion, you might try removing the switch from the equation. With the unit as supplied, it looks to me that re-routing the power cable to go directly to the transformer is possible without the run to the front of the unit. You would be reduced to removing the AC cord as means to power the unit on and off. But it may seriously reduce the "leakage" from AC.
If this does make a significant difference, then a "remoted" switch may be appropriate. ie a long stick.
I have not tried this, and leave it to others to try and report back.
This of course should have no affect on separation.
btw, lovely box
Thanks JensH

Most of the magnetic "leakage" comes from the transformer anyway.

Hi Jens,
I think most of us will happily wait for the shield upgrade. I'll try to update my firmware using a windows laptop. Maybe that will work better.
Otherwise, I'm very happy with the unit so far and only need to use it more to become familiar with the software (not a Jens issue!). The unit itself works as advertised.

Hi Jens
I have packed it out today.
Very nicely designed.
I did some basic testing and I am not 100% satisfied
Now until now I have a used a picoscope 4462 because it is fast to use. Using the software it possible to switch between scope and spectrum mode very fast making it possible to why distortion figures is not okay. But it has a limit of 0.001% when measuring on a dac.
I also uses it to check if there is any crosstalk between left and right, small amount can be due to bad soldering.
It is a usb powered scope. There is not issue with current loops. It is a 16 bit scope that with average can hit 20bit resolution but noise floor is hovering at -110dB
The noise floor is lower on the RTX 6001 which is good.
But I have a few issues.
1) 50hz hum at -135dB
2) crosstalk on the analog input. Somewhere the ground guard is not as it should be. That is not useful for me at all. -74dB if i have measured correctly at 1KHz. And it is not crosstalk from generator to input because if the cable is removed it is gone.
I am willing to be a testpig.

Hi Sonny,
I am not quite sure what you mean by item 2).
But I can always use a testpig 😀
No seriously, I wan't to understand the issue of course. We could also take this offline via PM and email etc., in a different language 🙂

Sure. Use the email for the proforma.
I am also looking at using it with software that has inverse RIAA and the low noise is really nice

Sometime ago you had post the attached pic.

I am going to correct myself it is -94dB crosstalk. Input attenuator selector was not set identically for left and right
In my past experience, it seems like shields with some iron actually perform better shielding against power line influences.
I'm guessing that the aluminum shield had no measurable effect.
I'll also guess that removing the switch ac path will have the same non effect. I suggested it as a test of measurement to those OCD inclined. I am not. I find the response and performance quite lovely as it is.
Now to find the really lovely software interface.......
