## 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 (???):
