Figure 5. NI 5663 Vector Signal Analyzer Nominal Dynamic Range, -20 dBm Reference Level
1
Reference level allows 10 dB headroom for single-tone input signals before digitizer clipping occurs.
The dynamic range plots in the two preceding figures show nominal
performance with NI-RFSA automatic coupled settings that are optimized
for noise performance. If you use the RF attenuation manual settings, IMD3
performance can improve with minimal degradation in noise floor, thus
increasing the effective SFDR in the power per tone signal range of 10 to 0 dB
below reference level.
