Non-LISN Insertion Loss Calibration
Insertion Loss values for coaxial cables and most measurement system
components having a single coaxial input and output, such as
attenuators, filters, dc blocks, etc., can be easily determined through a
simple calibration process.
The test setup for normalization and insertion loss measurements are
illustrated in Figure 12. The insertion loss factor is the difference (in dB)
between the normalization measurements and the insertion loss
measurements.
