Frequency (Hz)
Current Noise as a function of Frequency for several sensitivity settings (typical).
Note: The amplifier bandwidth and noise data were taken with the front panel frequency compensation
adjusted for flat frequency response over the widest frequency range, with an input capacitance of
100 pF. Either the bandwidth or the noise specification can be improved at the expense of response
flatness.
