Testing

After running artiq_sinara_test:

*** Testing Phaser DACs and 6 USER LEDs.
Frequencies:
phaser0 10+0 10+1 10+2 10+3 10+4 MHz

Upconverter

1. Install gqrx nix-shell -p gqrx
2. Connect bladeRF via USB cable only
3. Run gqrx and choose BladeRF #<number>...
4. Input rate 30000000, other settings are default
5. When gqrx loaded, start DSP processing with frequency near 2.875 GHz + frequencies from artiq_sinara_test in Receiver Options
6. Connect the probe through attenuator to the Phaser's ports
7. You should see 5 tones on artiq_sinara_test's frequencies, like on the picture below

Baseband

1. Install gqrx nix-shell -p gqrx
2. Connect bladeRF via USB cable only
3. Run gqrx and choose Nuand bladeRF SN <number>...
4. Input rate 15000000, other settings are default
5. When gqrx loaded, start DSP processing with frequency near 2.875 GHz (???)
6. Connect the probe through attenuator to the Phaser's ports RF0 or RF1 (not the ADC)
7. You should see 5 tones on artiq_sinara_test's frequencies (???):
