9 Digital Down-conversion (DDC) What is a digital down-converter? Real-time digital downconversion (DDC) It s a flexible processing block that allows an ADC to run at full rate while the output sample rate and bandwidth are optimized to match the signal under test. Digital signal processing Produces complex I&Q samples from real ADC samples Frequency translation (tune) Filter and decimation (zoom) 9

10 M9703A With DDC Option Details Main Functions: DDC on up to 40 phase-coherent channels (1.6 GS/s) Decimation factor by 4 then programmable by 2 n, leading to Sample Rate ranging from 400MS/s down to 200MS/2 N, N=0..18 Fine IF tuning (0.01Hz) over the full digitizer bandwidth (independent per channel) Channel Magnitude Trigger x40 Full Sample Rate (1.6 GSa/sec) Frequency Shift Decimation Filter 10

11 M9703A With DDC Option Details Interest for your application: Reduce the bandwidth and the sample rate to the appropriate values for the signal being analyzed. Setting the analysis bandwidth around the signal of interest, by shifting the center frequency Triggering on the signal of interest at a specified frequency and bandwidth Noise and other signals in the full ADC bandwidth are eliminated by the DDC, isolating the signal of interest, and increasing the dynamic range in the time-domain waveform through reduced total noise power. 11
