BETA

Advanced Impedance
Analyzer BetaNOVOCONTROLBETAThe Ultimate Tool For Electrical Materials
Characterisation
In physics, chemistry, biology, and materials sci­ence, the interaction of electrical charges and di­poles in materials with external electrical fields is ofparticular importance.
As a leading leading manufacturer of broadband
dielectric spectrometers, NOVOCONTROL Techno­
logies excels in modern measuring techniques us­
ing AC impedance methods for the electricalcharacterisation of materials.
Our BETA analyzer is the measurement solution ofchoice for researchers who need, in a single instru­
ment, a flexible input configuration for two­, three­,or four­terminal impedance measurements in thefrequency domain. NOVOCONTROL Technologies’
patented measuring techniques guarantee thehighest accuracy and reliability, making this instru­
ment first choice for sophisticated applications inR&D and QA/QC.
Stretching The Limits
Of Impedance Measurements
In impedance measurements, larger impedance
and frequency ranges substantially increase thenumber of systems, materials, and phenomenathat can be studied. Using state­of­the­art digitalprocessing techniques, NOVOCONTROL Technolo­
gies has succeeded in reaching formerly inaccess­ible performance, such as ultrahigh input
impedance, wide impedance range, ultralow ca­
pacity resolution and high tan δ resolution. Thesefeatures create new options for im­
pedance spectroscopy applications.
By separating the signal current andthe voltage sensing paths, the four­
terminal configuration of the BETA
analyzer, in particular, reduces theeffects of lead inductance and stray
capacitance which are particularly
important in case where samples
have to be connected via unusuallylong BNC cables.

Harmonics Analysis
In general, the electrical behavior ofmaterials is expected to be linear.
Some materials, however, exhibit an
intrinsic non­linear behavior or aredeliberately made non­linear for cer­tain purposes or applications. TheBETA analyzes higher harmonics ofsuch materials by complex Fouriertransformation. This opens the way to
a new range of experiments, known
as non­linear spectroscopy.
