Raw IQ File Writer

Quote from DevDW on 08/07/2022, 15:30Raw IQ File Writer block:
Left hand side input:
- IQ Streams
The Raw IQ File Writer records IQ streams to the selected file in the common "raw" IQ format of interleaved complex 32-bit floating point values. For a sequence x_0, x_1, x_2, ... of complex values, these are written to disk as follows:
[Real(x_0), Imag(x_0), Real(x_1), Imag(x_1), Real(x_2), Imag(x_2), ... ]
Make sure you have a capable SSD since the data amount can be huge! You might consider to use the IQ Demodulator to reduce the data size.
To start a recording first select a target file using the file chooser, then press record to start a recording.

Quote from hansencj on 13/10/2023, 06:00I'm trying to run two Raw IQ File Writer blocks in parallel to capture simultaneous data from RX 1 and RX 2. Unfortunately, I see a delay on one channel relative to the other. Is there a simple way to synchronize them? Ideally, I would like to capture about 1 second of samples from the two channels into the files.
