2.0 Introduction
This section describes antenna setup and mounting for EMI measurement.
2.1 Antenna Setup
2.1.1 Connecting
The model AH-118 horn antenna has an N type female connector. This connector
is used for signal input or output.
2.1.2 Antenna setup for receiving signals
The Model AH-118 antenna can be used to measure EMI from an equipment
under test (EUT). The antenna is mounted on either an antenna mast (such model
AM-400) or an antenna tripod. The antenna rear has a 1/4 inch x 20 threaded hole
for mounting on AT-100 series tripod or other similar tripod. A coax cable is
used to connect the antenna to the a measureing instrument. If a long cable is
used, cable loss must be measured and used in calculating the field strength.
2.1.3
Antenna setup for transmitting signals
When AH-118 antenna is used for transmiting signals, the antenna is mounted on
either on an antenna mast (such Model AM-400 antenna mast ) or antenna tripod.
To transmit signals, the antenna is connected to a microwave signal generator and
a power amplifier. The Model AH-118 antenna can transmit upto 400 watts
continious power. The field generated by the antenna can be measured by using
field strength probes or another horn antenna.
