Dual noise source drive capability typical application: Basic amplifier measurement application The basic amplifier measurement is the most common measurement mode of the noise figure analyzer for noise figure and gain measurement of the DUT without frequency conversion (including active, passive linear devices or systems such as amplifiers, filters, and isolators). System down conversion mode measurement application The system down conversion mode is a spread spectrum measurement for the amplifier type test piece. When the frequency range of the device under test is beyond the frequency range of the noise figure analyzer, the spread spectrum measurement of the noise figure is realized by an external mixer. The external mixer is used as part of the test system for calibration and measurement. In order to reduce the noise figure uncertainty, a mixer with low conversion loss and low noise figure is used as much as possible, and the intermediate frequency output port of the mixer is required to have good isolation of the local oscillator signal. Up and down converter measurement applications The device under test is an up-and down-converter device, such as a frequency converter and a transmitter or a downconverter and a receiver, whose output intermediate frequency is within the frequency range of the noise figure analyzer. In the up and down converter measurement, the 3986 series noise figure analyzer provides fixed IF, variable local oscillator and fixed local oscillator, variable intermediate frequency mode settings for testing the RF response characteristics and IF response of the device under test. characteristic.
