Quick Start Procedure - Linear Technology DC2460A Demo Manual

DEMO MANUAL DC2460A

QUICK START PROCEDURE

1. Connect all test equipment as shown in Figure 2.
2. Set the power supply output voltage to 3.3V, and set
the current limit to 500mA.
3. Connect the ground and V
BE SURE TO CONNECT THE V
THE 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 2753MHz CW
signal at about 0dBm to the demo board's LO port.

6. Set the RF signal generators to provide one 2599MHz
CW signal and one 2601MHz 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
RF1 input port. The two tones should be set to –8dBm
each at the mixer's RF1 input port.
7. Set the spectrum analyzer's center frequency to 153MHz
with a span of 10MHz. Combine the DC2460A IF1
–
and IF1 Outputs using a 180° combiner. Connect the
combiner's output to the spectrum analyzer.
8. Perform various measurements (Conversion Gain, OIP3,
LO leakage, etc.
