Noise - "Noise" refers to the noise generated internally by the integrator, with its primary frequency components corresponding to the low-frequency (-3dB) bandwidth.
High-Frequency (-3dB) Bandwidth - The indicated high-frequency (-3dB) bandwidth values are measured based on a 1-meter cable and 80mm coil. Longer coils and cables are available upon request.
