FRA5097 (0.1mHz to 15MHz, 2-channel, High Accuracy and Multifunction Frequency Response Analyzer)

Brand: NF
Model Series: FRA50x7 Series

About Product

A Frequency Response Analyzer (FRA) measures the gain and phase response characteristics with respect to frequency of the device or system under test by applying a frequency swept sine wave to it and examining its response signal, featuring wide dynamic range realizes high precise measurement, and also ultra-low frequency measurement. The NF FRA50×7 Series Frequency Response Analyzers comprise 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. Equipped with floating input circuitry and auto ranging functions for constantly optimizing input ranges, FRA50x7 Series allow dynamically changing frequency responses to be quickly measured with high accuracy, without the need to be concerned with input signal levels or the ground potential of the device being tested; moreover, operation is quite simple. The FRA50x7 Series will be your choice in selection. Experience first-hand just how excellent the accuracy, functions and operability they are.

Product Features

  • Display screen: 5” Color TFT LCD display allows for displaying the frequency response graph and setup menu of measuring conditions
  • High precision and 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
  • Frequency range: 1mHz to 10MHz (FRA5087), 0.1mHz to 15MHz (FRA5097)
    • From ultra-low frequency to high frequency
    • High density measurements of up to 20,000 points at one sweep are possible
    • Logarithmic equal interval setting and auto-magnification in sections where values greatly change are possible. Resolution is 0.1mHz
  • Gain accuracy: ±0.05 dB
  • Phase accuracy: ±0.3°
  • Dynamic range: 140dB
  • Isolation is achieved as oscillator output 2-channel and analysis inputs are isolated from the cabinet by 250Vrms. In this way, the instrument can be protected from damage by an erroneous signal connection
  • Auto ranging is possible as the input range is switched automatically according to the input signal level, so setup of voltage sensitivity is not necessary for the frequency response analyzer
  • Various graphical outputs as to Bode, Nyquist, Nicols and Cole-Cole plots
  • Impedance display function (Standard on FRA5097 and Option for FRA5087)
  • Basic Setup Key is available
  • Battery backup is possible as the contents of the setup and measured data stored in the memory before turning off power are held if power is turned off
  • Versatile interfaces: GPIB and USB are provided as standard
  • Built-in Printer for outputting hard copies of on-screen images onto thermos-sensitive paper is built-in, which makes saving measurements and creating reports convenient (See photo section)

Product Functions

  • Impedance display function (Option for FRA5087)
    • Impedance, resistance, reactance, admittance, conductance and susceptance to be accurately measured and displayed on linear and logarithmic graphs. Moreover, open-short correction, maximum and minimum value displays, and screen image storage can be done (See photo section)
  • Digital Fourier Transform and self-calibration function assure that measurements will always be highly accurate
  • Bode, Nyquist, Nicols and Cole-Cole plots can be displayed. Following measurement, interconversion is also available
  • Basic Setup Key is available as the basic setup screen is displayed simply by pressing the basic setup key. The upper lower limits, amplitude, and number of integrations for measuring frequency (sweep) can be set on one screen. The conventional model’s nuisance of setting each item by switching the screen can thus be avoided (See photo section)
  • Acting as a FRA servo analyzer by consistently providing high-quality measurements with excellent accuracy and functions upon the stability of servo systems

Product Application

  • Ideal for gain and phase response characteristics measurement
  • Loop characteristics of switching power supplies
    • Evaluate the dynamic stability (gain margin, phase margin) of a switching power supply. Since the signal source and measured terminal are mutually isolated, unrestricted connection is made possible, even with portions having overlapping direct current. The effect of a phase correction circuit can be measured clearly (See photo section)
  • Servo response for magnetic and optical disks
    • Measure transfer functions of servo systems which control the pick-ups of magnetic and optical disks, and measure open loop response in a normal operating status. It can also measure the phase of a high gain area in a stabilized condition because of its higher noise eliminating capacity, with measurement in a dynamic range of more than 140dB, by using the auto ranging operation at every measuring frequency (See photo section)
  • Impedance of electronic components
    • Measure inductance and impedance of capacitors. Since the frequency response analyzer can perform measurements by frequency sweeping, which differs from an LCR meter, a change of impedance characteristics by frequency can easily be known. Since it can perform measurements under a high voltage or large current in combination with a power amplifier, which cannot be done by an LCR meter, impedance can be measured in a condition closer to an actual state of use (See photo section)
  • Ripple rejection ratios of series regulators
    • Measure ripple rejection ratios for series regulators. The ripple rejection ratio characteristics are a major feature of a series regulator. Since the frequency response analyzer automatically removes a DC component of up to ±200V, it can measure a high voltage output of the series regulator with a high dynamic range of up to 140dB in combination with a power amplifier (HSA Series) (See photo section)
  • Resonance characteristics of piezo-electric components
    • Measure the electric resonance of piezo-electric components such as those used for piezo-electric actuators. The frequency response analyzer can provide high frequency resolution of a specified frequency range, which differs from FFTs, and then detailed characteristics near the resonance point can be known because of high phase accuracy, ±0.3°. By combination with the power amplifier, a large amplitude response can also be measured, not only the small amplitude response (See photo section)
  • AC impedance of fuel cells
    • Measure the AC impedance of fuel cells with an electronic load. Since the frequency response analyzer is not affected by direct current, impedance can be measured accurately with any output current from the fuel cell. Furthermore, measurement at a very low frequency 0.1mHz (almost DC) can be done. Moreover, it can be developed into a system which calculates the parameters (parasitic resistance, reactive resistance, double layer capacity) of an equivalent circuit from the results of measurement (See photo section)
  • Internal resistance of electric double-layer capacitors
    • Measure the internal resistance of an electric double layer capacitor placed intermediately between a capacitor and cell. The frequency response analyzer can perform measurements with a high resolution of up to 0.1mHz. It can also analyze Faraday impedance with Cole-Cole plots (complex impedance display). Moreover, since it is quite resistant to external disturbances, measurement while switching charging and discharging with a large current can be done (See photo section)
  • Market industries served include electronic circuits, electronic components, electronic materials, electro-chemistry, machinery and vibrations
