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.

• 7-TR Tripod—Constructed of PVC and
fiberglass components, providing
increased stability for physically large
antennas. The unique design allows for
quick assembly, disassembly, and
convenient storage. Allows several
different configurations, including options
for manual or pneumatic polarization.
Quick height adjustment and locking
wheels provide ease of use during
testing. Maximum height is 2.17 m
(85.8 in), with a minimum height of 0.8 m
(31.8 in). This tripod can support a

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.
