Frequency Selective Voltmeter Sierra 125

摘要

The procedure describes the calibration of the Sierra 125A frequency selective voltmeter, which is designed to measure voltage levels from -90 to +32 dbm over a frequency range from 3 to 620 kHz. A VTVM function is also available which measures voltage levels from -20 to +32 dbm over a frequency range from 1 to 620 kHz. (Author)
