Narda Safety Test Solutions has announced they have extended the range of application for their Interference and Direction Analyzer down to very low frequencies with a new loop antenna. The antenna is particularly suitable for detecting interference caused by switching power supplies or data transmission over electricity supply lines.
The new loop antenna for the Interference and Direction Analyzer IDA-3106 covers a frequency range from 9 kHz up to 30 MHz. Its typical antenna factor of 47.5 dB(1/m) at 1 MHz gives it unusually high sensitivity. Along with the new antenna, Narda also offers an improved antenna handle with a built-in, switchable preamplifier that covers the extended frequency range and increases sensitivity by an additional 20 dB if required.
Due to the high sensitivity, the antenna is particularly suitable for tracing defective or poorly screened switched mode power supplies or electrical controls that generate interference fields, for identifying interference due to data transmissions made using the power line carrier technique, or for demonstrating interference with other signals in the very low frequency range (VLF), e.g. using the time signal of the DCF77 transmitter.
The IDA-3106 Basic Unit is a hand-held device for on-site use that weighs less than three kilograms, including battery. The antenna and handle together weigh under one kilogram, as the power supply is from the Basic Unit. The battery can be hot-swapped without interrupting operation.
