|
|
|
| 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
