| Precision Test
Systems manufacture a range of items that can be used in UMTS
and or GSM propagation testing. These products have been designed against
customers requirements.
The range
consists of signal generators, power amplifiers and field strength
meters.
This allows a
high power signal to be generated to a test antenna. The field strength meter
is then carried around the site area and the signal level can be measured and
recorded.
Thus these
instruments allow complete propagation testing.
FSG Units (Field Signal
Generators)
The FSG (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 amplitude can be altered from +20 dBm to -20 dBm in 1 dB steps
(100 mW 10 μW).
The FSG960B
covers 890 MHz to 960 MHz and can be set in 100 kHz increments.
The FSG2170
covers 1710 MHz to 2170 MHz and can be set in 100 kHz
increments.
Both unit are
light weight, handheld, portable units operating from rechargeable batteries. A
LCD display shows the current frequency / output level
setting.
PA Units (Power
Amplifiers)
To increase the
output of the FSG units, two power amplifiers are 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 control.
The PA960B covers
890 MHz to 960 MHz and the PA2170 covers 1710 MHz to 2170 MHz.
FSM Units (Field Strength
Meters)
Various field
strength meters are available including the FSM series and 3201 / 3290
series.
The FSM 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
capture" mode.
The FSM960B
covers 890 MHz to 960 MHz and the FSM2170 covers 1710 MHz to 2170
MHz.
3290 Series (Field
Analyzers)
The 3290 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 measured.
