Com-Power AL-130R Active Loop Antenna
Frequency Range: 9 kHz - 30 MHz
The Com-Power AL-130R is compliant with CISPR 16-1-4. It is ideal for emissions measurements as required by various EMC standards such as FCC 18, CISPR 11, CISPR 13, CISPR 14, CISPR 32 and many more. The built-in, low-noise preamplifier, increases overall measurement sensitivity as well as the overall signal to noise ratio. As per ANSI C63.4-2014, the use of active loop antenna for compliance testing is permitted in a non-shielded environment ONLY if the saturation indicator is continuously monitored during the course of testing.
Com-Power AL-130R Active Loop Antenna Product Description
The AL-130R is an Active Loop Antenna (loop size: 19” x 19” [0.5 m x 0.5 m] with electrostatic shield), operating over the frequency range of 9 kHz to 30 MHz. It has a built-in, low-noise preamplifier, which increases overall measurement sensitivity as well as the overall signal to noise ratio. The antenna is battery powered (rechargeable 6V NimH battery pack). The AL-130R can also be powered by the supplied charger/power adaptor. The front panel has LED indicators for RF ON/OFF, power, battery low, amplifier saturation, as well as charging status.
The AL-130R is designed for durability, making it the ideal choice for daily use in most environments. It is constructed using high grade aluminium, which is also powder coated for additional durability.
The AL-130R Active Loop Antenna is intended for use as an EMI test antenna for qualification-level regulatory compliance measurements per most commercial product test procedures including, but not limited to, ANSI C63.4, along with most CISPR, EN, ETSI standards. Typically, the antenna is positioned vertically with the centre-point of the loop elevated one meter above the ground. The loop is then rotated about its horizontal and vertical axis to achieve the maximum reading at each frequency.
The AL-130R can be used for Electric field (E-Field) or magnetic field (H-Field) measurements. Factors are provided for both types of measurements.
Remote Operation (Optional)
As per ANSI C63.4-2014, the use of an active loop antenna for compliance testing is permitted in a nonsheilded environment ONLY if the saturation indicator is continuously monitored during the course of testing. Com-Power’s Remote Antenna Interface (RAI-100) comes in very handy for this application. The RAI-100 is a compact controller which is used to enable/disable the RF measurement circuit and monitor saturation and battery low indicators remotely via a fiber optic cable up to 30 mtrs in length.
