Using the IIP2 and DC Offset adjustment features:

Method 1 (On-board trim pots):
1. Install jumpers to all 6 positions of jumper block JP1
2. Apply 1V DC to VCTRL.
3. Connect EIP2 and EDC to VCC_SENSE.
4. Adjust REF trim pot until the voltage on the REF test point reaches 0.5V.
5. Adjust IIP2 and DC Offset using the on-board trim pots.

Method 2 (External voltage sources):
1. Remove jumpers from all 6 positions of jumper block JP1.
2. Connect EIP2 and EDC to VCC_SENSE.
3. Using 5 separate DC power supplies, apply 0.5V to each of the demo board REF, IP2I, IP2Q,
DCOI, and DCOQ test points.
4. Vary the voltages on IP2I, IP2Q, DCO1, and DCOQ to adjust IIP2 and DC Offset.
