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
