Connecting to Qdac 2 Array by Qdevil in Python
QDAC-II is the next generation of the successful QDAC from QDevil. It has all the outstanding features from its predecessor but is even more versatile and with superior performance. QDAC-II is a high-precision ultra-low-noise computer controlled DAC with 24 voltage generators, operating at a sample rate of 1MS/s – a thousand times faster than its predecessor. It is designed for DC and intermediate-frequency control of quantum devices, including, for example, gate electrodes and flux bias coils in qubits, but is a very versatile instrument that can be used for many other purposes. Each of the 24 channels has five voltage generators working in parallel: One for DC, a sine generator, a triangle generator, a square wave generator, and an arbitrary waveform generator (1 million points/second). Additionally, each channel is equipped with a DC current sensor with a resolution down to a few tens of pA, typically used for gate leakage detection and with sample rates up to 3 kHz.

Connect to the Qdac 2 Array in Python
PROTOCOLS > SCPI
To connect to a Qdac 2 Array Power Supplies using Qcodes Community, you can use the following code:
In the code above, you need to replace
listeners with the actual instances of the QDac2 instruments that you want to connect to. The
sync() method is used to synchronize the array of QDac2 instruments. You can then perform various operations on the Qdac 2 Array Power Supplies using the
qdac_array object. Finally, you can close the connection using the
