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 + frequencies from artiq_sinara_test in Receiver Options
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
