CTOnews.com, December 21, 2008. Recently, the electric science instrument has released a multi-channel arbitrary waveform generator, which is mainly used in the field of superconducting quantum computing, can regulate and measure qubits, and has a wide application prospect in quantum computing, quantum communication and other fields.

The instrument breaks through the technical problems such as multi-channel precision synchronization, high-quality waveform processing, multi-channel signal reception and fast feedback, and has the characteristics of high purity of control signal, arbitrary programming, multi-channel precision synchronization and so on.

CTOnews.com learned that the instrument model is 1652AM, and it adopts innovative precision synchronization technology and precise adjustable technology of waveform output delay. In any wave mode, the synchronization accuracy of four channels in the same module can reach 30ps, while the synchronization accuracy between different modules and multiple chassis does not decrease.

Each channel of the 1652AM has a storage depth of 512m sample points, vertical resolution 16bit, and DC bias can be accurately adjusted in the range of ±2V. The user can program the output signal of each channel to generate an "arbitrary" signal within the frequency range of the DC~400MHz.

In addition, 1652AM makes a special algorithm optimization for the pulse signal, which can not only ensure the fast signal edge time, but also achieve the pulse signal generation with low overshoot and high flatness, which can meet the stringent requirements of quantum computer to control the pulse signal generation.

1652AM not only supports traditional remote control instructions to download waveforms, but also supports users to download waveforms through Python transfer software, so as to avoid directly transmitting a large number of waveform data on the network wire, only need to send waveform instructions through the network cable, generate waveform data according to instructions in the Python transfer software, and then call dll to load, so as to improve the waveform loading speed.

1652AM multi-channel arbitrary wave generator is now in mass production. In addition, the options for high frequency waveform generation by quantum computer based on direct sampling technology and readout signal acquisition and processing will be launched in the near future.
