Description

The HLA 6120 is ideal for the 3 m magnetic field measurements as required e.g. by CISPR 11 (reference CISPR 16-1-4 and CISPR 16-2-3) and FCC 18. The built-in preamplifier matches the extremely low impedance of the loop to the measuring receiver. The HLA 6120 has a virtually constant factor over the whole of its frequency range, making it ideal for swept measurement systems.

One of the main reasons active HF antennas have not been widely accepted is the lack of overload warnings. With the HLA 6120 overload indications are given when signals are present at a level likely to cause nonlinearity in the preamplifier and thus impair the integrity of the measurement. This important feature detects the presence of high level signals, either pulsed or continuous, and gives a warning. Even single pulses (clicks) can be detected. For unattended measurements, a hold facility can be used. When the antenna is used remotely, TTL level logic signals provide a warning indication.

The antenna is powered by an external power supply / battery pack (CBP 9720), allowing operation both near to a mains power supply and in remote applications.
