This project is a work-in-progress.
Scalar network analyzer using a mix and match of the following components:
- HackRF
- RTL2832 based receiver
- Directional coupler/RF bridge/return loss bridge
- Noise source
- Signal generator (HackRF/rpitx)
To get phase information you would need a full-duplex transceiver or another HackRF (and tie their clocks together). I have none of those, so I'll leave that for the future.

SoapySDR has ABI incompatibility on Windows between Debug and Release builds. Since your PothosSDR release was probably built in Release mode, you must build this project with RelWithDebInfo or Release modes, or build SoapySDR in Debug mode.
It seems like at least one of the SoapySDR modules is
buggy. My guess is that
there is some contention with LibUSB between multiple support modules. A
stopgap measure is to disable all modules you do not need, you can do this on
Windows by going to C:\Program Files\PothosSDR\lib\SoapySDR\modules0.8 and
deleting/moving DLLs which are not necessary for your setup.
This project requires PothosSDR installed on your machine, which provides support libraries for various SDR hardware and SoapySDR. For the exact list of dependencies required, see the CI configuration.
To build, execute the following commands:
git clone --recurse-submodules https://github.com/netdex/hackrf_sna.git
cd hackrf_sna
cmake -S . -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build --config Release -j $(nproc) # or %NUMBER_OF_PROCESSORS% on Windows
