The Rohde and Schwarz
FS300 is a highly accurate spectrum analyzer with a frequency range of 9
kHz to 3 GHz. Owing to its modern, digital frequency processing
technique, it provides high measurement quality at an
High-quality measurement characteristics
Since the displayed average noise level is
typically -120 dBm (300 Hz), even weak signals can be reliably detected.
This is important for the measurement of spurious and harmonics. Within
the intermodulation-free dynamic range of the Rohde
and Schwarz FS300 no inherent distortions occur, which could
interfere with the measurement.
This is especially useful when a high
dynamic range is required, i.e. high and low levels are to be measured
simultaneously. Points in the measurement trace are displayed with a
level uncertainty of <1.5 dB. This value is unrivalled in this price
class and an essential prerequisite for high measurement accuracy.
Resolution Bandwidth from 200 Hz to 1 MHz
With 16 different digitally implemented
resolution bandwidths starting at 200 Hz, the R&S FS300 can be optimally
adapted to different measurement tasks. Large bandwidths for overall
measurements ensure short sweep times while small bandwidths provide
high frequency resolution and low noise level. The R&S FS300 fulfills
every requirement in between.
Frequency counter with 1 Hz resolution
With the aid of the built-in frequency
counter, the signal frequency can be measured with 1 Hz resolution in
the entire frequency range. An additional frequency counter is therefore
not required which saves space on the lab bench.
Maximum input level +33 dBm
The maximum input level of the R&S FS300
permits signals to be measured far beyond the common limits. Mobile
phones with a maximum output power of 2W can be directly connected to
the spectrum analyzer without external attenuators being required.
The R&S FS300 offers a number of measurement
and marker functions to support signal analysis. Two normal or one
normal and one delta marker are provided for determining the signal
The normal marker may be positioned as a
reference marker on the fundamental, for instance, while the delta
marker is positioned on a harmonic. The difference between the two
levels represents the harmonic suppression.
The normal or delta markers can also be used
as noise markers for measuring the noise power density. The n dB
bandwidth of a signal, e.g. the 3 dB or 6 dB bandwidth, can also be
easily measured with the R&S FS300.
Internal memory for settings and traces
Up to five traces and ten
settings can be stored in the internal memory of the R&S
FS300. Frequently used settings can be easily called up and
the same parameter need not be set over and over again. This
also prevents setting errors. Stored traces can be printed
for easy documentation.
Tracking Generator (FS315 only)
The FS315 with built-in tracking
generator is the perfect solution for cost-efficient
testing of the transmission behaviour
of filters, cables, amplifiers and
Equipped with an additional VSWR
bridge, reflection measurements
can also be performed. Entering any frequency offset between
0 Hz and 3 GHz allows measurements
on frequency-converting DUTs.
With simple applications,
the tracking generator can be used as a signal
generator with a permanently set
Remote control via USB
Another new feature of the R&S
FS300 is the USB remote-control interface. The user can
select external PC control even during instrument operation
by means of "hot plug and play" simply by establishing a USB
This is the first time that lab
test equipment can be remote-controlled via USB without any
restrictions. With the aid of the USB cable, the R&S FS300
can be operated even at positions which are difficult to
access, such as in a shielded chamber.
A Windows compatible
driver for different development environments is provided together with the R&S FS300. A PC
software package is also available for remote control of the
R&S FS300 and for result display and recording.
The R&S FS300 is notable for its
compact and robust design. Whether on the bench or in the
rack, it takes up a minimum of space. Two series instruments
can even be accommodated next to each other in a 19-inch
The new, adjustable handle
fulfills several functions. It serves for carrying the R&S
FS300. It can be moved and locked in almost any desired
position. With the aid of the handle, the instrument can be
set up in a tilted position so that an optimum viewing angle
can be obtained for the display. If the handle is in the
way, it can easily be put away so that several R&S FS300 can
be stacked, for instance.
High picture refresh rate
The high refresh rate of up to 10
pictures per second ensures smooth display of measurement
results. Changes of parameters during module adjustment are
thus rapidly displayed which saves time in development and
Ergonomic user interface
Operation is menu-guided so that
even untrained users will quickly obtain correct measurement
results. Clear structures simplify navigation within the
