ISN Calibration Kit
Com-Power’s ISN Calibration Kit provides all of the needed calibration
adapters/accessories. Also provided are detailed, step-by-step
instructions to intuitively guide you through the calibration of the following
electrical parameters:
9
Impedance -
[asymmetric - common-mode]
9
Phase
[asymmetric - common-mode]
9
Voltage Division Factor (VDF)
9
Decoupling Attenuation (Isolation)
9
Longitudinal Conversion Loss (LCL)
Generally, any of the folliowing combinations of test & measurement
equipment may be employed for the calibration:
Network Analyzer with [2-port] S-parameter capabilities
Spectrum Analyzer or EMI Receiver with Tracking Generator,
and Impedance Analyzer (or equivalent)
Spectrum Analyzer or EMI Receiver,
Synthesized Signal Generator,
and Impedance Analyzer (or equivalent)
Gain-Phase Analyzer with Impedance measurement capabilities
