Comparison: TDR Calibration Methods versus PNA SOLT Calibration
Device Under Test: 3.5 mm Thru Adapter
Results: The magnitude loss increases as a function of frequency and is dependent upon the
calibration method for TDR-based measurements. Phase error due to timing jitter exists in TDR-
based measurements.
Good Calibration yields ~1dB error below 10GHz
