The new high-end model R&S FSU50 complements the Spectrum Analyzer Family
R&S FSU from Rohde & Schwarz. The R&S FSU50
has a frequency range from 20 Hz to 50 GHz and is ideal for a wide range of
applications such as microwave, space travel and military applications. Even at
50 GHz, the R&S FSU50 still exhibits a very low displayed average noise
level of -118 dBm at 10 Hz bandwidth, and thus features the widest dynamic range
currently available. It offers an extensive scope of filter types with
resolution bandwidths of up to 50 MHz and comprehensive measurement functions
for precise power measurements even of wideband signals.
High-frequency performance is particularly important in the high-end range of
test and measurement. With a 1 dB compression point of the input mixer of 22 dBm,
a displayed average noise level of -142 dBm (at 10 Hz bandwidth and 2 GHz) or
-118 dBm, and a third-order intercept point of typically 13 dBm (at 10 Hz
bandwidth and 50 GHz), the R&S FSU50 offers maximum modulation capabilities.
Phase noise is extremely important for measurements on frequency-processing
equipment or when searching for interference signals. The R&S FSU50
furnishes superb values both close to the carrier and at larger frequency
offsets. At 10 MHz carrier offset, for example, it achieves -160 dBc (1 Hz).
The measurement accuracy of the R&S FSU50 is also extraordinary: In the
frequency range of up to 3.6 GHz, it achieves a total measurement uncertainty of
less than 0.3 dB; at 50 GHz, the value is still 3 dB without the customary
peaking of the preselection filters.
In addition to common test routines such as TOI, OBW and CCDF, the R&S FSU50
provides a wide range of power-measurement functions for determining channel and
adjacent-channel power. Channel width and spacing can either be selected
according to predefined standards such as WCDMA or configured by the user. In
conjunction with the RMS detector, these functions are ideal for precise and
reproducible power measurements of wideband signals.
Like all instruments of the R&S FSU family, the R&S FSU50 uses the
Embedded Windows XP operating system. A LAN interface for connecting to network
services is standard and makes the use of additional cards unnecessary. Using
the operating system's Remote Desktop function, the R&S FSU50 can be
remote-controlled via LAN or modem without requiring any additional software.
In production applications, measurement speed has top priority. Shorter
measurement times increase throughput and reduce costs for production test
systems. With a measurement speed of up to 80 sweeps/s in manual operation and
up to 70 sweeps/s in remote-control operation, the R&S FSU50 is currently
the fastest high-end spectrum analyzer on the market.
All software options of the R&S FSU family can also be used with the R&S
FSU50, which is now available from Rohde & Schwarz.
