DATA NORMALIZER FOR MICROWAVE MEASUREMENT OUTPUTS

摘要: In making microwave measurements, such as attenuation, VSWR, etc., over a broad frequency band, the resulting test values are obscured by highly variable characteristics of testing circuitry itself, which must be corrected for at all points (or any desired interest), from output curve to indicate true value item or component being tested, points. Where is logarithm input, correction can accomplished subtracting calibration values. The present disclosure describes system which, automatically and continuously during broadband measurement, makes this subtraction provides representing
