Embodiment Construction

[0036] Such as figure 1 As shown, the microwave multi-parameter measurement device consists of microwave measurement system I and microwave network analyzer II.

[0037] The microwave measurement system I is equipped with a VCO voltage-controlled oscillator 1, an isolator 2, a variable attenuator 3, an absorption frequency meter 4, a waveguide measurement line 5 with a stepping motor, a device under test 6 and a crystal detector 7. The VCO voltage-controlled oscillator 1 is used as the microwave source, which generates microwave power with adjustable frequency. Fixed voltage can also obtain voltages of different amplitudes and arbitrary shapes, especially sawtooth wave voltages, so it is convenient to provide point frequency and frequency sweep signals of different frequency bands. The pointer ammeter head 21 can be connected with a liquid crystal display 22 and a printer 23 . In order to realize automatic measurement, the slotted measurement line (TC26 type) 5 is modified, ...
