CHARACTERIZATION SETUP
SSB SETUP
Figure 54 is a diagram of the characterization test stand setup
for the ADL5386, which can test the product as a single sideband
modulator. The Aeroflex IFR 3416 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.

DETECTOR SETUP
Figure 55 is a diagram of the characterization test stand setup
for the ADL5386, which can test the product as a log detector.
The HP 8648D signal generator provides the input signal of the
detector. All currents and voltages are measured using the
Agilent 34401A multimeter.
