DWM3000 CIR time between samples

Hello,

I have a question regarding the channel impulse response of the DWM3000EVB (register file 0x15) and was hoping to receive some assistance. Specifically, I’m curious about the time delay between two samples.

Does anyone happen to know if the time delay is ~1ns, similar to the DW1000? Any insights would be greatly appreciated.

Thank you for your time and help!

Hi @Seba ,

Yes the time delay is ~1ns (the same as dw1000).
See in the driver API guide, you can find the information in the description of readacc function.

Hello, I’m using the new version, 1.0.2
The new document says that dwt_readaccdata is deprecated, and now we can use dwt_readcir.
As the hardware isn’t changed, I think the 1ns gap should not change either, but there is no mention about this in “dwt_readcir” section.
Does the 1ns gap still valid for dwt_readcir?

Hello, yes, it is still valid. 1 sample per ns.
