  • Arbitrary Impedance
    . Arbitrary impedance transformations allow measurements to be presented as if performed in the desired impedance. In an earlier era of rf/microwave testing, the measurement environment could almost always be assumed to be 50 ohms (or perhaps 75 ohms in the video-related world). Matching
  • BBG Tech Tips #5: Controlled Impedance (.pdf)
    impedance boards will require TDR (Time Domain Reflectometry). measurements that confirm the impedance values are within tolerance. TDR traces are. placed on a coupon that is located on the manufacturing panel. The coupon usually. contains several traces of some length (usually up to 8 inches long
  • Electrochemical Impedance Spectroscopy (EIS)
    Electrochemical impedance spectroscopy (EIS) is a powerful and accurate method for measuring corrosion rates. The corrosion rate at the monitored interface is proportional to the charge transfer resistance or polarization resistance. The actual relationship requires modeling of the interface
  • Measuring Low Value Resistance / Impedance
    A broad range of systems include components with very low resistance/impedance values such as current meters, force measurement devices, temperature sensors, battery/fuel cells, etc. Such impedance values can be in the range of 0.001 ohm to 0.1 ohm (maybe even smaller). In many cases
  • Impedance Battery Testing According to a Manufacturer of Test Devices
    of a cell that is the important parameter in determining a cell's state of health. Most AC impedance or conductance devices, whether they are monitors or portable instruments, do not measure the true resistance of a cell and do not provide reliable state of health information. Very little has been
  • LCR Measurement Primer (.pdf)
    This primer defines and explains the measurement of the impedance parameters known as L (inductance), C (capacitance), and R (resistance). Impedance parameters are characteristic of an AC circuit; this primer describes the impedance measurements that are typically used, including their equations
  • Battery Impedance Monitoring...An Added Dimension (.pdf)
    Testing. The measurement used to predict most valve regulated lead acid (VRLA) battery failures today. is impedance. An ac perturbation is placed onto the battery system such that an identifiable. current of frequency and magnitude flows and impresses a resultant ac voltage drop across the. cells
  • Measure Impedance And Insertion Loss In USB 3.0 Cables And Connectors
    and cables results in considerable distortion because of channel dispersion. To keep this distortion to manageable levels, the standard specifies the impedance and return loss for mated cables and connectors. The latter measurement is represented by the S-parameter, S11. It must be normalized
