HIOKI 3145-20 Noise HiLogger
Measures the noise levels and frequencies on telecom, power and grounding lines
Easily view the noise current level in each band. Record noise level variations over time in each band. Measures noise current on earth lines easily. Hard to detect One-Shot noise with a spectrum analyzer or oscilloscope, are reliably captured. Data can be automatically saved to a PC Card, continuous long-term recording.
