2.0 Introduction
This section describes antenna setup and mounting for EMI measurement.
2.1 Antenna
Setup
2.1.1 Connecting
The and Model ALC-100 Log Periodic Antennas have N type (f) connectors. The
same connector is used for both signal input and output.
2.1.2 Antenna setup for receiving signals
The or Model ALC-100 antenna can be used to measure EMI from an equipment
under test (EUT). The antenna is mounted on either an antenna mast (Model AM-
400) or an antenna tripod. A cable is used to connect the antenna to the a measu-
reing instrument. If a long cable is used, cable loss must be measured and used in
calculating the fi eld strength.
2.1.3 Antenna setup for transmitting signals
The Model ALC-100 antenna can be used to receive and transmit signals. The an-
tenna is mounted on either on an antenna mast (Model AM-400 antenna mast ) or
antenna tripod (Model AT-100). To transmit signals, the antenna is connected to a
signal generator and power amplifi er. The Model ALC-100 Log Periodic Antenna
can transmit up to 500 Watts continious power. The fi eld generated by the antenna
can be measured by using a fi eld strength meter.
