Power Measurements for 600

Low Power

Low power measurements: As of 12/8/05

The low power measurements were done with 1GHz oscilloscope via 1m RG241 cable. The high power measurements were done with power meter via approx. 40dB attn. The data in the tables is corrected for attenuation. 15N and 13C amplifier outputs were non-linear between -6dB and -3dB
