Using ZCU216 for controlling multiple flux qubits
JavierSerranoGarcia opened this issue · 6 comments
After using the RFSoC4x2 and the ZCU111 boards for control and readout of qubits now we are starting with the ZCU216. The first issues we found are
- The sampling frequency for the DACs is fs=6881.280 MHz. Can it be changed or is there a different version with a sampling frequency of around 9 GHz (like in RFSoC4x2)?
- Is there a multiplexed readout version of the firmware like in ZCU111?
- Is there a better solution for the flux DC signals than external differential amplifiers like in the ZCU111? (we are using the companion board that comes with the ZCU216).
I really appreciate any help you can provide.

Maybe this will work for you: https://www.slac.stanford.edu/~meeg/qick/fw/2023-04-17_216_q3diamond_full688and958/
The DAC coupling works the same in the ZCU216 as in the ZCU111, you need external differential amplifiers in either case.
Hi Sho,
Thank you for the new firmware. We are trying to use it but we do not know how to use the
4 constant-IQ outputs:
0: DAC tile 1, ch 0, fs=6881.280 MHz
1: DAC tile 1, ch 1, fs=6881.280 MHz
2: DAC tile 1, ch 2, fs=6881.280 MHz
3: DAC tile 1, ch 3, fs=6881.280 MHz
Which channels should we use to send pulses?
The constant-IQ outputs play constant tones. They are not what you want for pulses; you should use the regular generators. They are there, no?
But in case we want to use them for something like a bias what should we do?
Thank you so much
