The R&S®FSH8 is a spectrum analyzer and depending on the model
and the options installed – a power meter, a cable and antenna
tester and a two-port vector network analyzer. It provides the
three most important RF analysis functions that an RF service
technician or an installation and maintenance team needs to solve
daily routine measurement tasks. For example, it can be used for
maintaining or installing transmitter systems, checking cables and
antennas, assessing signal quality in broadcasting,
radiocommunications and service, measuring electric field strength
or in simple lab applications. The R&S®FSH8 can perform any of
these tasks quickly, reliably and with high measurement accuracy.
Weighing only 3 kg, the R&S®R&S®FSH8 is a handy instrument.
All frequently used functions have their own function keys and are
within fingertip reach. The brilliant color display is easy to read
even under poor lighting conditions, and it has a monochrome mode
for extreme conditions.
The capacity of the R&S®FSH8 battery enables uninterrupted
operation for up to 4.5 hours. The battery is changed within
seconds. And if it rains? No problem – all connectors are
splash-proof.
Power measurements on pulsed signals
By means of the TDMA POWER function, the R&S®FSH8 performs
time-domain power measurements within a time division multiple
access (TDMA) timeslot. To make work easier for the user, all
required instrument settings are already predefined for the GSM and
EDGE standards.
Channel power measurements
The R&S®FSH8 determines the power of a definable transmission
channel by means of the channel power measurement function. A
channel power measurement for the LTE, 3GPP WCDMA, cdmaOne and
CDMA2000® 1x digital mobile radio standards is performed at a
keystroke.
Field strength measurements with directional antennas
When measuring electric field strength, the R&S®FSH8 takes into
account the specific antenna factors of the connected antenna. The
field strength is displayed directly in dBμV/m. If W/m2 is
selected, the power flux density is calculated and displayed. In
addition, frequency dependent loss or gain, e.g. of a cable or
amplifier, can be corrected. For simple result analysis, the
R&S®FSH8 provides two user-definable limit lines with automatic
limit monitoring.
Quick function selection via keypad and rotary knob
The R&S®FSH4/FSH8 is operated via the keypad and rotary knob.
The selected function can be activated directly using the Enter
button integrated into the rotary knob. The vertical design puts
all operating elements within fingertip reach. The MODE key is used
to switch between the various operating modes such as “spectrum
analyzer“, “vector network analyzer“, “digital modulation analysis“
and “power meter“.
All basic settings can be conveniently made in a straightforward
list. Measurement results, including instrument settings, are saved
to the internal memory, the replaceable SD memory card or to a USB
stick. Predefined instrument settings can be locked to prevent them
from being changed unintentionally. This reduces the risk of
incorrect measurements.
The USER key allows frequently required measurements to be
collected in a single menu. User-defined instrument setups are
assigned to softkeys under a user-definable name
Optimal reading of measurement results in any situation
The measurement results are easy to read on the brilliant, clearly
laid out 6.5" VGA color display. The backlighting of the display
can be adjusted to the ambient lighting conditions. For use in
extremely strong sunlight, a special monochrome mode provides
optimal contrast.
