DISCONTINUED ITEM

High-end functionality noise measurement instrument provides long-term recording and remote control functions. The 3145-20 is designed to measure noise that changes frequency or level over time, as well as one-shot noises such as surges.

  • View instantaneous noise levels in a bar graph.
    The 3145-20 separates noise between 10 kHz and 100 MHz into seven frequency bands, and displays the noise current level of each band as one bar in a bar graph, which is refreshed every 100ms.  Just clamp around a signal line and start measuring immediately.
  • Record noise level variations over time.
    Variations in the noise levels of the seven frequency bands over time are recorded in the instrument’s internal memory. By analyzing logged data, long-term and periodic noise levels can be captured and the timing of the noise occurrence can be determined.  The recording interval can be set from 1 to 60 seconds. The peak level of noise measured within each recording interval is recorded.
  • 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 recordingNote: Clamp on Noise Sensor 9754 is required
  • Input terminal :  BNC (max. input voltage 5V peak), 5kHz to 100MHz (-3dB)
  • Measurement ranges : [Current] 0.2mA, 2A, 20A (used with the 9754).[Voltage] 10mV, 100mV, 1V
  • Band Path Filter characteristics : Center frequency: 15k, 70k, 250k, 1M, 5M, 20M, 60MHz, 7 BPFs separates noise (fixed), measuring the peak value in each band
  • Monitor function : Displays real-time peak-to-peak values in each frequency band on level meters, Refresh interval: 100ms
  • Logging function : Records maximum peak-to-peak values in each frequency band at the specified recording interval to internal memory (16 days at 1sec interval to 2.5 years at 60sec interval)
  • Recording interval : 1, 2, 5, 10, 20, 30, 60 sec
