Impedance
Adapters for impedance measurements and impedance spectroscopy
4-terminal adaptor
Turn your network or signal analyzer into an impedance analyzer. The adaptor enables measurements of the voltage over and current through the device under test by analyzers having two input channels. The impedance is simply calculated as the complex ratio between the voltage and the current. The adaptor connects to an industry-standard 4-terminal interface, thus allowing use of a variety of third-party test fixtures.
Impedance adapter
Our standard version of the impedance adaptor has a fixed transimpedance conversion factor for the current channel to suit most applications. As a unique feature, the impedance adaptor includes controllable channel swapping to suppress differences between the current and voltage channels. Ask for demo / sample code to put your digitizer into use as an impedance analyzer. Download the product sheet here.
Impedance adapter, extended impedance range
This version of the impedance adaptor has a programmable source impedance for the generator stage and a programmable transimpedance conversion factor for the current channel to widen the impedance measurement range. The impedance adaptor also includes a controllable channel swapping to suppress differences between the current and voltage channels. Ask for demo / sample code to put your digitizer into use as an impedance analyzer. Contact Apparateq to find out more.
Impedance standards
For traceable calibrations of the impedance adapter and your analyzer a set of calibrated resistance standards are available.
Sound-card impedance adaptor
Dedicated to impedance measurements of loudspeakers using soundcards. The adaptor isolates the device under test from your PC, and offers an improved measurement range.
Soundcard impedance adaptor kit
The impedance adaptor comes in a kit with USB power cable, two 3-pin mini jack cables, and an application note. Contact Apparateq to find out more.
Analyzer cables
For use with soundcards with phono connectors or with signals analyzers with BNC connectors, this cable kit includes two splitter cable from 3-pin mini jack to phono, a stereo phono cable, one mono phono cable, and three phono to BNC adaptors.
