Excellent frequency stability with Anapico’s APMS-ULN multi-channel signal generators
Anapico’s APMS-ULN multi-channel signal generator products are now available up to 20 GHz, enabling excellent frequency stability, phase coherence and extremely fast tuning speed. Each channel can be programmed independently in frequency, phase, amplitude and modulation.
Channel-to-channel phase coherence: With the new generation of the APMS, the channel-to-channel phase coherence has considerably improved. While the phase error was ±10 mrad (0.6 degrees) at 1 GHz over a period of 10 hours on the old generation, it is now less than ±1 mrad (0.06 degrees) on the new generation.
Unit-to-unit phase stability: Thanks to the dedicated clock synchronization mode that was added on the new generation, the unit-to-unit phase coherence is equivalent to the one achieved within a single unit. Thus it is possible to extend a single unit to virtually any number of channels while the phase coherence remains unaltered.
