Model 1252A Frequency Response Analyzer
The model 1252A Frequency Response Analyzer is one of a range of
instruments that will meet your needs today and in the future.
Using the single sine technique the 1252A provides precise
measurement of gain and phase between any two points in a system.
This fully digital technique is used to assess the performance of
both simple and complex systems - mechanical, electronic and
electrochemical. For over 30 years Solartron Analytical have
produced frequency response analyzers, instruments which are
regarded throughout the world as industry standards. This
unsurpassed knowledge and experience has been used to produce the
1252A, with its 300 kHz frequency range and 1 in 65 million
frequency resolution.
The 1252A Frequency Response Analyzer applies the power and
sophistication of modern measurement technology; simple in concept,
fast and precise in performance, and so easy to use, even by
non-technical personnel. The 1252A Frequency Response Analyzer’s
key features include:-
- Measures gain, phase and group delay
- Unbeatable accuracy - 0.2%, 0.02dB, 0.2º
- Deep dynamic range - 130 dB with autoranging
- Wide frequency range - 10 µHz to 300 kHz
- Ultrafine frequency resolution up to 1 in 65 million
- Automatic sweeps of frequency, amplitude or DC bias
- Automatic rejection of noise and harmonics
Electrochemistry
Measurement of impedance has become an important tool in the
study of electrochemical/biological phenomena and material
properties.
The 1252A together with a potentiostat such as 1287, can be used
in a wide range of applications, including:-
- Corrosion and corrosion protection
- Properties of organic and inorganic coatings and films
- Development of solid electrolytes for oxygen sensors
- Development of novel anode/cathode materials and electrolytes
- Studies of animal and plant tissue properties
- Photoelectric effects
Materials Testing
When combined with a 1296 Dielectric Interface and temperature
test equipment the 1252A can be used to test a wide range of
materials, such as:-
- Supercapacitor/fuelcell electrochemistry
- Relaxation processes in the molecular dynamics of liquid
crystals, polymers and liquids
- Charge transport in semiconductors, organic crystals, ceramics
etc.
- Analysis of chemical reactions, polymerization and curing
processes
- Novel gas and liquid sensors
- Characterization of insulating and semiconductor materials
- Quality control in the production of insulators, printed
circuit boards, etc.
Electronic Testing
The model 1252A is ideally suited to a wide variety of
applications in the field of electronics - from fundamental aspects,
such as the characterization of the electrical and mechanical
properties of materials, to the development and testing of
components and complete circuits.
Generally these applications require the measurement of transfer
functions and group delay over a wide frequency range. In the case
of filters, a wide dynamic range coupled with high frequency
resolution are also needed to enable the attenuation characteristics
to be full defined.
Consider the model 1255A if manual
operation is required or for frequencies up to 20 MHz.
