Basic Operation

1. Connect

the

signal generator output

to the

OSCin

input of the board. For this example we use a 10

MHz sin signal at +5dBm power level.

2. Connect a low noise

5.0 V

power supply to the

Vcc

connector located at the top left of the board.

3. Please

see

Appendix C

for quick start on interfacing the board. Connect PC to the

uWire

header.
