CHARACTERIZATION SETUP
SSB SETUP
Figure 43 is a diagram of the characterization test stand setup for the ADL5385, which is intended to test the product as a single-sideband
modulator. The Aeroflex IFR3416 signal generator provides the I and Q inputs as well as the LO input. Output signals are measured
directly using the spectrum analyzer, and currents and voltages are measured using the Agilent 34401A multimeter.
