instruments allow complete propagation testing.
FSG Units (Field Signal
(field signal generator) series are handheld, portable
signal generators especially designed to cover the UMTS
and GSM frequency bands. Each unit generates a CW
signal. The units are synthesized and the
frequency is simply entered into the keyboard. The

available. When used with the FSG series, the
power amplifier will generate a CW signal from 2 mW to
20W. The power amplifier has a levelled output and
is controlled by the FSG unit with automatic gain

FSM Units (Field Strength Meters)
field strength meters are available including the FSM
series and 3201 / 3290 series.
series are small handheld portable units that measure
the signal strength appearing at the units input socket.
Levels from +20 dBm to -110 dBm can be measured to an
accuracy of 3 dB. They are narrow band units that
only measure one channel frequency at a time. The
frequency of interest is entered into the unit and the
synthesiser sets the field strength meter to that
frequency. The FSM units measure CW or AM signals
and will also capture GSM signals using the "peak

3290 Series (Field Analyzers)
field strength meter is a portable unit covering the 100
kHz to 2.9 GHz frequency range in one unit.
An LCD display shows the field strength in various
frequency channels. The 3290 can also be set to
scan multiple channels. An RS232 interface and PC
control software allow measurements to be downloaded to
a PC. Input levels from -60 dBm to -10 dBm can be
