SECONDARY STANDARDS LABORATORY MEASUREMENT SYSTEM OPERATION PROCEDURE HV-06 VOLTAGE STANDING WAVE RATIO 3/8' COAXIAL, TYPE N CONNECTOR (100 TO 1000 MC)nPREPARED PRINCIPALLY

摘要

This procedure describes the operation of a secondary standards laboratory calibration system which is used to measure the voltage standing wave ratio of 3/8 inch coaxial instruments having type N connectors, and in the frequency range from 100 Mc to 1000 Mc. Single-ended instruments such as signal generators and terminations or double-ended instru¬ments such as attenuators, directional couplers, or filters having a VSWR up to 10:1 can be calibrated with this system.nThe instrument under calibration will be referred to herein as the Test Instrument.nThe estimated system instrumentation accuracy is given in Section 3. The over-all accuracy achieved during instru¬ment calibration, however, must take into consideration the operator errors in manipulation and readout as well as the inherent system accuracy.
