Product Description

Noise HiLogger with 9754 Clamp
Electrical noise interference is a major cause of trouble with electronic device such as damage malfunctions and communications disruptions. Model 3145-20 is an on-site noise measurement instrument designed to measure the conducted noise that appears on power earthing and telecom lines resulting from ingress of radiated noise. Using the 3145-20 can shorten the time required for noise investigation and development of countermeasures suppression.
By employing a non-contact noise sensor investigation of noise affecting electronic devices can be performed simply in the active state. The instrument simultaneously displays the noise levels in multiple contiguous frequency bands and a peak detection function can be used to reliably capture one-shot noise surges such as from lightning contact switching and ESD. By recording and displaying noise measurements as a time series the timing and other characteristics of the noise can be seen at a glance.
Advanced Features
- Lightweight and compact for easy on-site noise investigations
Until now large and expensive measurement instruments were required for noise analysis making on-site noise investigations often problematic. Model 3145-20 is a small lightweight instrument dedicated to noise measurement and especially suitable for on-site noise investigations. - Non-contact noise sensor
The non-contact noise sensor eliminates the need to worry about electric shock or communications disruption even when measuring noise on active power telecom and earth lines. - Measurement frequency range corresponds to most radiated electromagnetic noise
The 3145-20 measures noise over the broad range of 10 kHz to 100 MHz so it is able to measure a wide variety of noise. - Noise levels displayed on a large LCD
Detected noise is separated into seven contiguous bands each of which is displayed simultaneously in a bar graph so you can see the nature of the noise at a glance. - One-Shot noise detection
One-shot noise such as surges and ESD noise which are hard to detect with a spectrum analyzer or digital oscilloscope are reliably captured by the peak detection function. - Capable of measuring earth line noise
Because the HiLOGGER measures noise current noise on earth lines that had been difficult to measure can now be measured easily. - Records noise level fluctuations over time
The HiLOGGER records and displays fluctuations of noise over time in seven frequency bands ideal for long-term noise monitoring and investigating times of event occurrence. It can also monitor unpredictable noise events. Noise fluctuations over time can be displayed as a time-series graph on the instrument's LCD. - Alarm function
An alarm sounds when the noise level exceeds a specified threshold. Alarm occurrence levels and times are automatically recorded so the dates and times of rare and unpredictable noise interference events are revealed. - Network connection
A LAN terminal is included for connection to an intranet or to the Internet. Remote control of the instrument and measurement monitoring can be performed using a Web browser such as Internet Explorer. In addition alarm notifications can be sent by e-mail. - Bundled PC application program
Noise measurement data recorded on the 3145-20 can be viewed on a personal computer. Additional program capabilities include a search function for finding measurement data according to specified criteria time-series graph printing and CSV format conversion.
