Rohde & Schwarz FSH6 Handheld Spectrum Analyzer 100 Khz to 6.0 GHz
Description of Rohde & Schwarz FSH6
The Rohde & Schwarz FSH6 spectrum analyzer is a wide band, very
sensitive receiver. It works on the principle of "super-heterodyne
receiver" to convert higher frequencies (normally ranging up to
several 10s of GHz) to measurable quantities. The received
frequency spectrum is slowly swept through a range of pre-selected
frequencies, converting the selected frequency to a measurable DC
level (usually logarithmic scale), and displaying the same on the
CRT of the Rohde & Schwarz FSH6. The CRT displays received signal
strength (y-axis) against frequency ( x-axis).
Some applications for Rohde & Schwarz FSH6 Spectrum Analyzers
include Site Monitoring: Verify that the frequency and signal
strength of your transmitter is accurate. Interference: Before a
system is installed you use a Rohde & Schwarz FSH6 spectrum
analyzer to verify that the frequencies (you plan to use) are not
occupied or if the presence of a very strong signal will interfere
with your new setup. Interference can be created by a number of
different situations. Other tests that utilize the Rohde & Schwarz
FSH6 spectrum analyzer features include antenna isolation,
co-channel interference, adjacent channel power, occupied
bandwidth, intermodulation, microwave or satellite antenna
alignment, and characterization of components.
The FSH is the ideal spectrum analyzer for rapid, high-precision,
cost-effective signal investigations. It provides a large number of
measurement functions and so can handle anything from the
installation or maintenance of a mobile radio base station up to
on-site fault location in RF cables as well as development and
service -an extensive range of applications. Due to its excellent
characteristics, the FSH is used on board the International Space
Station (ISS) for distance-to-fault measurements on RF antenna
cables

The FSH performs time-domain power measurements within a timeslot
of TDMA (time division multiple access) methods. All the settings
required for the GSM and EDGE standards are predefined to make
these measurements easier for the user. In addition, up to five
user-definable instrument setups can be loaded into the FSH using
the FSH View software
Channel-Power Measurements
The channel-power measurement function is for determining the power
in a transmission channel specified by the user. After a few
preliminary settings have been made, a single keystroke starts the
FSH's spectrum measurement inside the channel, using a resolution
bandwidth that is small relative to the channel bandwidth. The FSH
then integrates the measured values indicated by the trace to
obtain and display the total power. All the settings required for
the digital mobile radio standards 3GPP WCDMA, cdmaOne, CDMA2000 1x
are predefined ready for use. The FSH also takes the
characteristics of the selected display mode (lin or log), the
selected detector and the resolution bandwidth into account so that
the result accuracy is comparable to that obtained with a thermal
power meter.
Measurements on Cables (distance-to-fault)
For rapid and accurate determination of the distance to any faults
in an RF cable. Distance-to-fault measurements using the VSWR
Bridge FSH-Z2 give an immediate overview of the state of the device
under test (return loss and distance). The marker-zoom function
allows detailed analysis of faults with a resolution of up to 1024
pixels.
Requires FSH313/323/626 (with built-in tracking generator), option
FSH-B1 (distance-to-fault measurement) and FSH-Z2 (VSWR bridge and
power divider).
Scalar Network Analysis
The FSH313/323/626 (with built-in tracking generator) can be used
to determine the transmission characteristics (i.e. attenuation or
gain) of two ports such as cables, filters, amplifiers, etc,
rapidly and with a minimum of effort. A simple calibration
procedure compensates for the attenuation introduced by measurement
cables or any attenuators used for amplifier measurements. When the
VSWR Bridge FSH-Z2 is attached, the matching (return loss or VSWR)
at the input or output of two ports can be determined as well as
their transfer function. The bridge is screwed directly onto the RF
input and tracking generator output, and no extra or cumbersome
cabling is required.
