Overview
The ETS-Lindgren 3107B Parallel Element E-Field Generator can Generate large electrical fields over the frequency range of 10 kHz - 30 MHz for RI testing. The 3107B was the first commercially available E-Field generator, and still remains the first in many areas. For example, the 3107B is still the only E-Field generator that uses two transformers; one for frequencies below 5 MHz, and the other for frequencies 5 MHz and above. Each transformer is matched to a narrower frequency band, so the antenna performs with greater efficiency. A manual bandswitch, located on the front of the unit, allows you to switch transformers at the cross-over frequency.
