LimeSDR Mini: Holes in the recorded data

Projects LimeSDR

Hello,

I suspect I have “holes” in the recorded data.

So I wrote:

config.channel[0].rx.testSignal = true;

Before running:

device->Configure

What wave shape should I get ?

Does this shape depends on parameters like: sample rate, gain, bandwidth etc. ?

I followed the sample code basicRX. The while loop contains:

int SamplesRead = stream->StreamRx(pDst, Rest, &rxMeta);

But there is no use in rxMeta. Should I use it somehow to make sure there are no holes in my recording ?

Thank you very much,

Zvi

Test signal is generated digitally, so it’s not affected by analog parameters. The produced data is continuous wave of sample_rate/8, or sample_rate/4

rxMeta contains timestamps, you can check if it increments by the number of samples you read.
