## JSON
```json
{
"type": "phaser",
"hw_rev": "v1.1", // optional
"ports": [<port num>]
}
```
## Testing
```text
*** Testing Phaser DACs and 6 USER LEDs.
Frequencies:
phaser0 10+0 10+1 10+2 10+3 10+4 MHz
```
After running `artiq_sinara_test`:
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 with adjusted resistance (???) to the Phaser's ports
7. You should see 5 tones on `artiq_sinara_test`'s frequencies, like on the picture below
