N7000/1/2/3A Probe Head Characteristics
The characteristics listed in the
amplifier using different probe heads. The characteristics are mainly determined
by the probe head. Performance with the lower bandwidth amplifiers
(N7000/1/2A) is the lower of the following values:
• Amplifier BW, 0.434 / amplifier BW, 0.308 / amplifier BW
• Bandwidth measured with the highest bandwidth amplifier (N7003A).
