|
## Setup
|
|
|
|
|
|
|
|
|
|
Check if [SUServo](./suservo.md) is enabled/disabled on customer needs.
|
|
|
|
|
|
|
|
|
|
## Testing
|
|
|
|
|
|
|
|
|
|
After running `artiq_sinara_test`:
|
|

All urukul channels active.
|
|
|
|
|
Check each channel amplitude (~1.6Vpp/8dbm at 50ohm) and frequency.
|
|
|
|
|
Frequencies:
|
|
|
|
|
urukul0_ch0 10MHz
|
|
|
|
|
urukul0_ch1 11MHz
|
|
|
|
|
urukul0_ch2 12MHz
|
|
|
|
|
urukul0_ch3 13MHz
|
|
|
|
|
Press ENTER when done.

|
Press ENTER when done.

```
|
|
|
|
|
|
|
|
|
|
1. Setup oscilloscope's impedance at 50 ohm
|
|
|
|
|
2. Touch each connector with oscilloscope, setup time- and voltage- scale and trigger, so that you can see sine waves
|
|
|
|
|
3. Measure frequencies and amplitudes on each connector, check with `artiq_sinara_test`'s respective values
|
|
|
|
|
4. When done, proceed with `artiq_sinara_test` and check LEDs are lighting up one after another
