1.1 Features
The “FRA5087 Frequency Response Analyzer” is a type of frequency response analyzers that
feeds swept frequency signals to a system under test.
The “FRA5087 Frequency Response Analyzer” comprises a sweep oscillator subsystem with a
frequency synthesizer incorporated that generates signals to be fed into the system under test, an
analyzer subsystem that measures responses of the system under test for swept frequency signals,
operates outcomes of Fourier integrals and calculates amplitudes and phases of the response
signals, and a recorder/display subsystem that records and displays the measurement results.
a) High precision, wide dynamic range
The built-in oscillator uses a synthesizer system to maintain high frequency accuracy and
resolution. By using a high-resolution A/D converter as well as an auto-ranging operation,
the analysis section allocates an increasingly wider dynamic range and, furthermore, Fourier
integrals and a self-calibration feature enable consistently high-precision measurements.
b) Insulated I/O terminal
The two analysis inputs and the oscillator output are independently isolated from the
enclosure.
c) Wide band between 0.1 mHz and 10 MHz
The entire range between 0.1 mHz and 10 MHZ can be swept and measured all at once.
d) Color TFT-LCD included
The built-in color TFT-LCD displays the frequency characteristic graphs and measurement
condition setup menus.
e) USB flash drive supported (USB host connector located on front panel)
You can use USB flash drive (attached) to store the setting and measurement data. (The
behavior of non-attached USB flash drive is not guaranteed). The file format is compatible
with Windows 98 SE or later on IBM PC/AT compatible machines, which means IBM PC/AT
compatible machines with a USB port can read/write the applicable files.
f) Setting and measurement data battery backup
The present setting values and measurement data stored in an involatile memory will be
retained even after shutting down the power.
g) GPIB/USB as standard equipment
You can set the measurement conditions and read measurement data while using an external
PC.
h) Thermal printer included
A thermosensitive printer that enables hardcopy outputs of the LCD screen is built in. This
printer is useful for saving the measurement data and preparing reports.
i) Impedance display available
By combining FRA5087 with an amplifier or a shunt resistor, impedances can be measured in
a wide range of voltages and amperes that normal LCR meters cannot cover. In addition, use
of the impedance display feature facilitates accurate measurement and displaying of the
impedances (option).
