Application of RF Micropotentiometers for Calibration of Signal Generators to 1000 McU.S. Department of Commerce, National Bureau of Standards, 1960 - Electronic apparatus and appliances - 14 pages With the RF micro-potentiometer, signal generator output voltage can be calibrated to 1000 Mc simply and accurately if the procedures outlines in this paper are carefully followed. The sources of error are discussed and methods for minimizing or eliminating them are described. Topics discussed include: RF shielding, selection of a suitable RF detector, impedance matching and the proper selection of voltage reference planes. |
