[Wiki](https://github.com/sinara-hw/Phaser/wiki)

## JSON

```json
{
   "type": "phaser",
   "hw_rev": "vX.Y", // optional
   "ports": [<port num>]
}
```

## Testing

After running `artiq_sinara_test`:

```text
*** 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 `Nuand bladeRF SN <number>...`
4. Input rate 20000000, other settings are default
5. Lower the gain in `Input options`
6. When gqrx loaded, start DSP processing with frequency near 2.875 GHz +- DUC frequencies from `artiq_sinara_test`
   in `Receiver Options`
7. Connect the probe through attenuator to the Phaser's RF ports
8. You should see 5 tones on `artiq_sinara_test`'s frequencies, like on the pictures below for RF0 and RF1 respectively:

### 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 (???):
