Different HackRF One-s give inconsited behaviour

Open VasilyRakche opened this issue 3 years ago • 2 comments

What would you like to know?

Hi, I have two HackRF One-s, but the behaviour is different between the two. Running the t1_checking_signals.zip, can be seen on the picture: image
With one HackRF I get the following:
hackRF_working_ok
And with the second one I get the following:
hackRF_working_strange

What is strange is the DC offset is different, I also noticed that the noise floor is a bit higher. What do you think?

Where did you get each HackRF from? Can you please post pictures of both?

Hey, thanks for the fast response. Both of them were ordered in the same place : https://www.elektor.de/great-scott-gadgets-hackrf-one-software-defined-radio-1-mhz-to-6-ghz

Here are the pictures (I marked the one with the bigger noise): 20220908_103214 20220908_103222

To help me diagnose this can you please repeat the test with the RF gain set to 0? Ideally the test would be done with a cabled RF signal generator.
