Connect the 5 V dc power supply to the 5V test point, and the
ground connection to the GND8 test point. The 3.3V and 1.8V test
points are for evaluation purposes only. Connect the spectrum
analyzer to the Southwest SRI 2.92 mm connector, RF_OUT.
Connect the Southwest SRI 2.92 mm connectors, LO_N and LO_P,
differentially to the low phase noise frequency generator.
Use a 180°
hybrid from 5.4 GHz to 10.25 GHz for the differential inputs. In IF
mode, connect the IF_I and IF_Q inputs to the frequency generator
through a 90° hybrid from 800 MHz to 6 GHz for the quadrature
inputs. Keep the I/Q inputs floating and remove any jumpers from
the ADMV1013-EVALZ evaluation board.
In I/Q mode, connect the I_P, I_N, Q_N, and Q_P inputs to the
I/Q baseband generator. Plug the USB cable into the mini USB
connector XP2to connect the PC to the ADMV1013-EVALZ
evaluation board (see Figure 5, Figure 6, and Figure 7). Use the
AD5601 nano DAC on the ADMV1013-EVALZ evaluation board
to generate the control voltage (V
CTRL
) voltage. See the Setting
V
CTRL
Voltage for the ADMV1013 section for additional details.
If the ADMV1013 needs a hard reset, use Reset Button S1 to hard
reset the ADMV1013-EVALZ evaluation board.
