How network analyzers based on direct digital synthesis (DDS) provide an extra performance boost for an edge in the latest 5G component test. DDS sources create signals digitally using a numerically controlled oscillator. On each digital clock cycle, the phase accumulator receives a delta phase value (ΔΦ). The accumulator then generates phase values based on each ΔΦ value for the phase-to-amplitude converter. The phase-to-amplitude converter uses a lookup table to match each phase value to the c
