TESEQ HLA 6120 环形磁场天线
天线因数低且平滑可与大多数EMI接收机配套使用具有脉冲过载报警功能
产品特点：HLA 6120是3米磁场测量的理想工具，符合CISPR 11 (参考CISPR 16-1-4和 CISPR 16-2-3)标准和FCC 18标准要求。内置的前置放大器匹配测量接收机的低阻抗要求。

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. Overload Warnings for Confidence of Measurement 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. Power Sources 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.
