The AnaPico APVSG is an ultra-agile fast-switching vector signal generator series, covering a continuous frequency range from 10 MHz  to 4 , 6, 12,  20 or 40 GHz. The standard APVSG enables outstanding ultra-fast CW frequency sweeping, chirping, intra-pulse modulation, frequency hopping, pulse shaping, all with very low phase noise. A high performance internal I/Q modulator enables customized modulation waveforms and supports dedicated modulation schemes, including avionics modulation. Now also available in multi-channel rack-mountable versions APVSG-X with 2, 3 or 4 independently adjustable channels. The multi-channel vector signal generators are phase-coherent.
