Information

The MH680B Tracking Generator is used in conjunction with the MS61 OB Spectrum Analyzer as a wideband sweep signal Generator which measures amplitude vs. frequency response by direct observation. The output frequency of the MH680B when used with the MS610B can be set in the range from 100 kHz to 2 GHz by using the MS61OB frequency dial. The output level of the MH680B can be varied continuously in the range from -10 to 0 dBm. The MH680B, with the MS610B, can be used to measure the frequency response of filters, amplifiers, and attenuators. The device under measurement can be adjusted while directly observing the characteristics on the MS610B CRT display. Also the MH680B with the MS610B and a frequency counter, can be used to measure the accurate frequency and frequency response. Impedance can be measured by direct observation using a directional coupler or a reflection bridge.
