Power Measurements for 500

Low Power

The low power measurements were done with 1GHz oscilloscope via 2m RG241 cable. The high power measurements were done with power meter via approx. 40dB attn. The data in the tables is corrected for attenuation.

Changed:
<
<		Low power measurements: As of 1/11/06.
>
>		Low power measurements: As of 1/13/06.
