Step 4. Setup Synthesizer
1 Insert one end of an SMA cable to the synthesizer’s
RF OUT SMA connector and the other end of the cable to the
applicable microwave test equipment as shown in Figure 32 (for
microwave synthesizer modules) or Figure 33 (for millimeter-
wave synthesizer modules).
2 Insert the Mini-B end of a USB cable into the Synthesizer’s USB
connector and the A-Type end into the computer’s USB receptacle.
3 Ensure that the power supply is turned off before connecting DC
cables. Verify that the voltage of the power supply is set be-
tween +12 V and +12.5 V.
4 Connect the black (ground) wire of the DC bias power cable to
the power supply.
5 Connect the red (+12 V) wire to the power supply.
6 Insert a 30-pin SPI connector into the synthesizer’s SPI connec-
tor receptacle.
7 Turn on the power supply. The power-on indicator on the
millimeter-wave synthesizer modules will illuminate blue light.
The indicator appears on the small printed-circuit board on the
front panel. The microwave synthesizer modules do not have
power-on indicators.
WARNING
Voltage less than +11.4 V at the synthesizer connector may result in
malfunction, and voltage in excess of +15 V may damage the synthesizer.
CAUTION
The QuickSyn Lite Frequency Synthesizer generates heat; therefore, use a heatsink
or ensure adequate (i.e., ≥ 1 cfm) airflow is present to prevent the synthesizer’s
internal temperature from exc75° C.
NOTE
Model FSL-7682’s RF OUT connector is a WR15 waveguide connector, which is
not depicted in any of the illustrations in this guide.
