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 adapter. The front panel has LED indicators for RF ON/OFF, power, battery low, amplifier saturation, as well as charging status.
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.
As per ANSI C63.4-2014, the use of an active loop antenna for compliance testing is permitted in a non-sheilded environment ONLY if the saturation indicator is continuously monitored during the course of testing.Com-Power’s RAI-100 Remote Antenna Interface 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.
