Stretching the limits of gain/phase testing 1250 series Frequency Response Analyzers The 1250 series of Frequency Control Systems The 1250 series together with a Response Analyzers (FRA) provide a potentiostat such as 1287, can be A standard use for a FRA is to generate range of accurate solutions for the used in a wide range of applications, a signal which is connected to a signal measurement of gain and phase. including:- converter (this may take many forms; The device under test is stimulated by e.g. hydraulic, pneumatic or electrical),Corrosion and inhibitor studies a sinewave and the response analyzed which forces controlled movement to Analysis of organic and inorganic at one, two or more points in the take place (e.g. displacement coatings and films system. These responses are then transducers used in aerodynamic Research into solid electrolytes for correlated with the stimulus to tests). These are placed on the system oxygen sensors/fuel cells determine the amplitude and phase under test and the output signal fed relative to the generator. The ratio of back to the FRA via a sensor, enablingDevelopment of novel anode/cathode the two measured signals can then be the system to be characterized. Typical materials and electrolytes used to provide the system transfer uses include:- Bioanalytical research into plant/soil function. Automated test systems properties This process rejects all harmonics and, Power supply testing by increasing the integration time, Materials Testing Aircraft instrumentation/system even signals which are buried in noise When combined with a 1296 Dielectric controls can be measured accurately. Interface and temperature test Aerodynamic tests - study of applied The 300V range on the 1250 series is equipment the 1250 series can be forces to wing structures particularly useful for making used to test a wide range of materials, measurements on fuel cell stacks andCar shock absorbers such as:- high voltage batteries, used in hybrid Weapons guidance systemsSupercapacitor/battery/fuel cell vehicles and residential power supplies. materialsRocket propulsion and vectoring technology The 1250 series FRAs key featuresCharge transport in semiconductors, include:- organic crystals, ceramics etc. Electrochemistry Analysis of chemical reactions,ac amplitude range - 10mV to 10V, Measurement of impedance has polymerization and curing processes for power supply testing become an important tool in the study Novel gas and liquid sensorsAnalyzer range - 300V, ie for ATS of electrochemical/biological (Automated Test Systems), power Characterization of ferro/piezoelectric phenomena and material properties. station vibration testing and semiconductor materials Noise rejection capability Synchronizer option enabling generator and carrier signals to be locked in terms of frequency / phase Ability to analyze non-linear systems Multiple channel analysis - 1254 FRA has four channels in parallel Front panel or software (Visual Basic) control Modulator / demodulator card for interfacing to ac carrier systems 1250 series Frequency Response Analyzer Specification Synchroniser Generator The synchroniser option enables the Waveform sine, square, triangle generator to be locked to a rotating / Frequency range: 10µHz to 65kHz reciprocating component, and max resolution: 10µHz: ±100ppm measurements can then be made stability (24hrs, ±1ºC): 10ppm relative to this.
