1.0 Introduction The wide band design of the ETS-Lindgren Model 3107B Parallel Element E-Field Generator allows operation over the entire 10 kHz to 30 MHz frequency range in two bands: Band 1 covers the frequency range from 10 kHz to 5 MHz, and Band 2 covers 5 MHz to 30 MHz. For portability, the Model 3107B elements are easily attached and removed. Attach each the element by rotating it clockwise into the Model 3107B body until it is firmly connected; to disassemble, rotate each element counterclockwise.
Tripod Options The Model 3107B includes a tripod mount that can be attached to a standard tripod. ETS-Lindgren offers the following non-metallic, non-reflective tripods for use at both indoor and outdoor EMC test sites. • 4-TR Tripod—Constructed of linen phenolic and delrin, designed with an adjustable center post for precise height adjustments. Maximum height is 2.0 m (80.0 in), and minimum height is 94 cm (37.0 in). This tripod can support up to an 11.8 kg (26.0 lb) load.

4.0 Assembly and Operation 1. Attach the support rod to the mounting plate on the bottom of the Model 3107B Parallel Element E-Field Generator by rotating it clockwise into the plate until it is firmly connected. 2. Attach the support base to the support rod by rotating it clockwise onto the rod until it is firmly connected. 3. Attach the Model 3107B assembly to a standard tripod (not included) by rotating the support base clockwise onto the connector on the tripod.
4. Attach the signal source to the Type N connector on the Model 3107B. Use a voltage monitor or power monitor at the signal source to determine the input voltage/power applied. The field strength capability is shown in the tables on page 14 and page 16. A field intensity monitor on the opposite side of the Model 3l07B from the test sample and at the corresponding distance will give a good approximation of the field seen by the sample.
