@Spanishwolf2005 @MouserElecEU @ADI_News If @MouserElecEU sent you a replacement - they were doing you a giant favour. According to @ADI_News terms of sale : https://t.co/YhMG61FKZ3

Evaluation board or kit: Any evaluation board or kit (like a PlutoSDR) is provided “as is” without any representation, warranty…

@jacquesrouxsa @G4GUO It’s 2 channels. A (for 30MHz <-> 300 MHz) and B (for 200 MHz <-> 6 GHz). Doing a proper match between 30MHz and 6 GHz is pretty difficult

@ico_TC @F4DAV @G4GUO @Thewekendfull ADRV9002 & ADRV9009 are NOT the same die. check by looking at pinout. While they are in the similar packages (196 ball chip scale), they are massively different (check datasheets).

Reliability data on ADI website also says that ADRV9002 is 28nm & ADRV9009 is 65nm.

@ico_TC @M_Labs_Ltd Yes - SATA on MPSoC is connected via dma. It’s just “hard” ip, on the ARM tile. That why they draw it like that.

@ico_TC There is some doc at: https://t.co/LORmTrt0BY

@M_Labs_Ltd @ico_TC At the time I was involved in things - many people wanted to deploy and capture to disk - for long term applications. (SATA on MPSoC is ~6Gbit/s; theoretically faster than USB3).

@BMenkuec @aang254 @GerhardSchweiz1 Many of these clone projects always seem to fail to maintain their firmware and keep up. The last FW for ant seems to be 0.35 (Jul 19, 2022). https://t.co/bttlZ96784 however - the latest Firmware for Pluto is 0.38 (Nov 17, 2023) https://t.co/QrqwONXiRM

@aang254 @GerhardSchweiz1 Sorry AntSDR is not “high end”. 16 channels of 20 GPSP is high end. Libiio is for those sorts of systems.

[Robin Getz 🇨🇦 @robinlgetz]

@aang254 @GerhardSchweiz1 “The FPGA” side - was what it was designed for. That’s how nearly all end users use libiio. CPU is not fast enough for GSPS - so why bother? And the increase for the streaming folks who are in the mid MSPS - will be satisfied by libiio 1.x

[Robin Getz 🇨🇦 @robinlgetz]

@aang254 @GerhardSchweiz1 It depends on your use case. Many, many commercial users use it for GSPS and above. But they do most of their signal processing in the FPGA, not CPU. For that - it’s perfectly fine.

[Robin Getz 🇨🇦 @robinlgetz]

@aang254 @GerhardSchweiz1 >libiio is atrociously unreliable.
I’m not sure what you mean? It’s super reliable - people use it across lots of use cases. Kid it the fastest - no. But libiio 0.x was never designed for that - that’s what libiio 1.x is for.

@popo_junior20 @ghidraninja Sorry mouser link was wrong. Try this: https://t.co/um5fwYQPVK

[Robin Getz 🇨🇦 @robinlgetz]

@popo_junior20 @ghidraninja Pluto SDR is available and in stock at:
- https://t.co/Tw9pJp299V
- https://t.co/h4yRidHxwj
- https://t.co/saBNi3zIiU
- it’s also on Amazon (for more $ via resellers)

[Robin Getz 🇨🇦 @robinlgetz]

@popo_junior20 @ghidraninja I would not use the words “improved”. Different, based on same RF chip, I have not tried it - so I don’t know - but the Pluto+ GitHub has not been updated in 2 years. That doesn’t make me comfortable. It’s based on 0.33 of the PlutoSDR firmware (which released 0.38 last week)

[Robin Getz 🇨🇦 @robinlgetz]

@ea4gpz @BMenkuec @AndrePuschmann “In our testing, we found the system to be quite stable.”tested on one part - at the same voltage, at room temp - may be enough for an SDR enthusiasts- but not enough to ship a product. When tested over process, voltage & temp (PVT) you will see different results - It will fail.

@f1ubl if you need them - the Hammond 2D/3D models for the enclosure are at : https://t.co/kvb4Z33mK2

[Robin Getz 🇨🇦 @robinlgetz]

@dymangh @DutraCGI I will see if I can replicate things - and if I can find a problem - will let you know.

[Robin Getz 🇨🇦 @robinlgetz]

@dymangh @DutraCGI By default IIO scope tries to resume from last time - and will reload settings found in the ini file. You need to either remove the file or start it pointing to a non-existent file to do what you are saying.
