Re: Anlogue output levels
If you're looping out of the RCA out, directly back to the RCA in, you should not be seeing a ~10dBf drop in levels. This large of a gain change will only occur when going through devices that have different signalling levels (presuming no DI box or etc is being used inline to compensate for this i...

Re: Anlogue output levels
Sure Valis. My test is the signal from the DAW which I’d dBfs to the analogue out looped backed to the analogue in back into the DAW. The signal reads much lower on the dBfs scale which means the conversion by the scope D/A RCA outs is in the realm of -10dBv. When I test the XLR loop back signal it ...

Re: Anlogue output levels
This is correct. Dbfs is a measurement in the digital realm and shouldn't be applied to analog levels. I understand that. My question is the output level at the D/A stage which means there has to be a voltage level. Recording the output back into the analogue input shows the drop in level which mea...

Anlogue output levels
I'm just testing my setup and I've setup an analogue (RCA) out to in loop to record the signal. My question is what is the output level converted to by the A/D? Is it a line level 0dBvu out. -18dBfs so to speak?
Thanks
Thanks

Re: PCI Express x1 to PCI/PCI-X Adapter Card
I‘m no expert in the mobo domain, but as an example (long story made very short): My Win7 PC runs from a PCIe flash disk, data drive is an USB3 SSD, no SATA drives, Pulsar II running fine, though a fairly low performer in PCI bandwidth (the machine was never intended to run Scope). For some reason ...

Re: PCI Express x1 to PCI/PCI-X Adapter Card
why? an adaptor is not the same as an actual PCI slot, performance-wise, and you will have to really modify the case to use the card. if you must use obsolete gear, get a motherboard that supports it. jmho. I would just like to use an old Pulsar I card’s DAC for the analogue outs on an updated mobo...

that‘s the opposite ;) you need this type https://www.amazon.co.uk/StarTech-com-PCI-Express-Adapter-Card/dp/B0024CV3SA?th=1 (they have several, didn‘t check them all) but the rised card won‘t fit regular case backs (as mentioned) :lol: that’s what happens when I don’t sleep.

Re: PCI Express x1 to PCI/PCI-X Adapter Card
The PCI connector spacing looks like it’s for 3,3V cards, not Pulsar II’s 5V. I have a similiar one with a 5V slot that does handle Scope cards fine - but there isn‘t much to recognize as the PGA chip more or less just switches slot signals between the 2 environments. If in use the added height mov...

Re: Sine Wave test
Can only guess since I don't know neither what you use to generate or analyze the sine wave. But generally, unless the oscilloscope applies a sinc function, high frequencies will become jagged since unlike the output from the DAC which has sinc applied, it will just draw a straight line between sam...

Re: Phase issues
I'm happy fra77x2 had the time to go into a long explanation..Busy week here. Phasefix-x is a good tool to verify when this is occuring imho. What I do is simply use the invert button to verify that there is indeed a phase shift. This only works with a mono signal of course, where there's no "...

Would this work to hold a Pulsar 2 PCI card? Will it still recognise the card?

Re: AMD Ryzen 9 3900X
You can still find mobo with pci, but they are industrial boards, while the 3900x is consumer line. At work we just bought boards with Xeons and 2 pci slots. ( You even could still buy ISAslots these days !) Can they compete with these CPUs though? I will never give up scope but the x54 bit O/S has...

Re: AMD Ryzen 9 3900X
Ok thks Gary. I have the MSI one to keep my pci alive. I still think the Scope DSP sound quality is great. A shame it can’t solely by used for that on modern boards. They look so so fast and efficient now. DSP still has it’s benefits

Are there any MOBOs that support this with a single PCI or is PCI a bottleneck in the modern day?

Would it be possible to just add DSP assignment to dNa plugins for phase compatibility in my mastering chain. I believe this would be a perfect addition with the DAW.

Is it possible to modify devices in SDK. When I import a device it asks me for the key but the device doesn’t load after I’ve imported it. Is the SDK just for new creations?

After the phase issue discussion and fra77x2 advice would it be possible to create a device which forces a device on a single DSP to avoid phase issues?
Thanks
