Impedance Analyzers of Wayne Kerr 

6500 Series 

The new 6500P range offers the widest range of HF Impedance Analyzers currently available. The corresponding price range means that users will be able to select a model which meets their requirements and is priced accordingly.
Engineers need to evaluate component characteristics at high frequencies with very high levels of accuracy.
The 65120B 120MHz Precision Impedance Analyzer is therefore ideal for many demanding tasks, combining accuracy and ease of use at an affordable price. If a frequency range up to 120MHz is not required then the other models are available in this range.


  • Characterize components from 20Hz to 120 MHz
  • Models defined by their maximum frequency which ranges from 5MHz to 120MHz
  • Precise high frequency impedance measurements
  • 0.05%basic measurement accuracy
  • Comprehensive measurement functions
  • Easy to use with large TFT touch screen
  • Clear graphic displays
  • Intuitive user interface
  • Fully programmable over GPIB
  • Replaces 6500A series
  • Competitively priced

6430B and 6440B (preferred Capacitance)

The 6430B and 6440B Precision Impedance Analyzers provide thorough and accurate testing of any passive component to high resolution. In particular, for capacitor manufacturers, the instruments provide capabilities for both fast automatic production testing and complete design characterisation.
Users include designers of passive components, manufacturing test, designing and testing materials as well as circuit designers who are evaluating component characteristics. The resonant frequency can be automatically calculated for any component together with its equivalent series or parallel circuit at that frequency. Both instruments are designed for high performance testing of components, with a basic accuracy of 0.02%, at a low price. 6430B is the entry level instrument covering to 500 kHz whilst the fully featured 6440B covers to 3 MHz.


  • Fast automatic impedance testing
  • High measurement accuracy on dissipation factor
  • Fast measurement speed
  • 0.02% basic measurement accuracy
  • Comprehensive measurement functions, Graphical sweep on all measurement functions
  • Characterize components to 3 MHz
  • Large LCD display and intuitive user interface
  • Unbeatable price

3255B and 3260B (preferred Inductance)

The 3255B range of inductance analyzers are able to accurately characterise devices in a clear and simple manner. The inductance analyzers are available in three versions 3255BL (200kHz), 3255B (500kHz) and 3255BQ (1 MHz). At the design stage of component development it is very important to analyse how components performs under different operating conditions. This includes operation over a range of frequencies, AC drive levels or DC bias currents. The AC drive level can be set between 1 mV and 10 V. DC bias current can be set from 1 mA to 1 A internally (optional). Using the external 3265B range of DC Bias Units bias currents can be set to a maximum of 125 A.


  • Frequency ranges from 20 Hz to 1 MHz
  • Fast measurement speed - up to 20 measurements per second
  • 0.1% basic accuracy
  • Up to 125 A of DC bias current
  • Comprehensive measurement functions
  • Straightforward intuitive operation
  • Print test results
  • GPIB control with LabVIEW™ driver
