Active Rod & Field Antenna
Information
The ETS-Lindgren Model 3301B is a broadband, high sensitivity
Electric-Field Receiving Antenna. The unit is composed of
monopole rod Antenna with a counterpoise and a broadband, high
impedance pre-amplifier. The unit is designed to provide
reception
of an electric field in a signal band without tuning or band
switching from 30 Hz to 50 MHz. The 3 dB roll off points for the
Antenna factor are at 170 Hz and 30 MHz. Between 250 Hz and 20
MHz, the Antenna factor is flat within +/- 1 dB. Despite the
roll of
the unit’s Antenna factor, the usable range is 30 Hz to 50 MHz.
The 3301B has been designed for maximum sensitivity and
dynamic range. The 3301B is capable of sensing fields of
dBuV/m at 1 MHz with a 1 kHz bandwidth. However, it will not
saturate below a field strength of 0.7 V/m. Hence, the unit
boasts
an extremely wide dynamic range of 115 dB nominal at mid-band.
In addition, at 10 and 30 dB (+/-10%) internal attenuators are
provided. With the attenuators the unit is usable in fields
of up22 V/m. Thus the dynamic range of the unit is expanded
to 145 dB.
A saturation indicator is provided to alert the user to the
need for
using the internal attenuators.
The Model 3301B has been designed to provide the user with an
extremely versatile measurement tool. Its flat Antenna factor,
extreme sensitivity and ultra-wide dynamic range make it a
state of
the art sensing instrument.
