Based on latest Direct Digital Synthesizer (DDS) and Field Programmable Gate Array (FPGA) technology, TOPTICA offers with the VFG 150 not only another 150 MHz arbitrary waveform generator but a novel approach to phase-controlled, coherently driven experiments in atom, ion and condensed matter physics.
Phase-controlled frequency switching of rf signals
The VFG 150 allows to predetermine the amplitude, frequency and phase of its sinusoidal output with a dwell time down to 100 ns. This unique feature permits the user to operate the frequency generator in various switching modes. Phase con-tinuous switching preserves the actual phase when changing from one frequency to another. In phase-coherent mode, the phase at the switching time is set such that the new rf oscillates in phase with a virtual rf of same frequency started at the beginning of the experimental sequence. Additionally, it allows for a user-defined phase offset maintaining the phase information of a given frequency all the time.
Unlike arbitrary waveform generators, which are limited by their internal memory, the VFG 150 can emit infinitely long signal trains with a very high complexity. |
