Versatile RF signal generators suit quantum applications

Saelig Company, Inc. has introduced Rigol DSG5000 Series RF Microwave Generators, which can generate high-quality RF signals up to 20GHz with amplitude, frequency, phase, and pulse modulation capabilities. These generators are available with 2, 4, 6, or 8 independent RF channels housed in a 2U rack-mountable case. The series of signal sources feature an impressive +/-1° long-term phase stability between channels and they are designed for high-frequency work in applications like radar and quantum research. Each of the up to eight channels can be independently controlled with a channel-to-channel isolation of more than 75dB, a frequency resolution of 0.01Hz, phase deviation resolution of 0.01°, and a switching speed of 3ms. The generators provide an output power adjustable from -30dBm to +25dBm, with a phase noise of -133dBc/Hz @ 1GHz (10kHz offset), a fast switching speed of 3ms and an amplitude accuracy of +/-1.1dB (typical).

This series of RF Signal Generators meets the needs of complex tests such as superconducting quantum computing, radar signal generation, MIMO, EMS, etc. Single or multiple qubit manipulation is the basis of complex quantum algorithms. The series multi-channel coherent microwave signal generator supplies a stable base for realising multiple qubit and stable vibration signals by generating multiple coherent and ultra-low phase noise microwave signals. Multiple units can be cascaded to achieve multi-channel coherent output, supporting larger-scale qubit gate operations.

The series offers a channel density that is eight times greater than the previous Rigol DSG3000B series, making the DSG5000 generators an outstanding solution for complex multi-channel and system-level applications. They can be controlled from a 3.5" touchscreen interface or remotely, with a local PC, or via an internet connection: just enter the IP address of the series into a web browser to open the Web Control software. The series also provides for a wide range of external displays via an HDMI interface.
