quick start proceDure (Dc2483a-a)
1. Connect all test equipment as shown in Figure 3.
2. Set the power supply output voltage to 3.3V and set
the current limit to 60mA.
3. Connect the ground and V
ply.
BE SURE TO CONNECT THE V
EN TURRET TO ENSURE THAT THE PART DOES NOT
GET DAMAGED. ALSO, REMOVE POWER FROM EN
TURRET BEFORE REMOVING POWER FROM THE V
TURRET.
4. Connect the EN turret to the power supply.

5. Set the LO signal generator to provide a 3360MHz CW
signal at about 0dBm to the demo board's LO port.
6. Set the RF signal generators to provide one 239MHz
CW signal and one 241MHz CW signal. The signals
should be applied to the 2-way combiner. The output
of the combiner should be applied to the demo board's
RF input port. The two tones should be set to –12dBm
each at the mixer's RF input port.
7. Set the spectrum analyzer's center frequency to
3600MHz.
8. Perform various measurements (conversion gain,
OIP3, LO leakage, etc.).
5. Set the LO signal generator to provide a 1040MHz CW
signal at about 0dBm to the demo board's LO port.
6. Set the RF signal generators to provide one 899MHz
CW signal and one 901MHz CW signal. The signals
should be applied to the 2-way combiner. The output
of the combiner should be applied to the demo board's
RF input port. The two tones should be set to –12dBm
each at the mixer's RF input port.
7. Set the spectrum analyzer's center frequency to
140MHz.
8. Perform various measurements (conversion gain,
OIP3, LO leakage, etc.).
