Embodiment Construction

[0008] The technical solution of the present invention will be further analyzed in conjunction with implementation below, but the following content is not intended to limit the scope of protection of the present invention.

[0009] Attached below figure 1 The present invention is specifically described:

[0010] like figure 1 As shown, a scalar network analyzer in this embodiment can perform transmission test and reflection test, and the scalar network analyzer has extended spectrum display, field strength observation, and point frequency output functions.

[0011] The reflection test function has two display modes: return loss display and standing wave display. The transmission test function has two sub-functions: amplitude-frequency characteristic graph and insertion loss test. The signal source function can output the radio frequency signal of the set frequency, and adjust the size of the signal within a certain range through the built-in output attenuator. The output a...

Abstract

The invention discloses a scalar network analyzer capable of performing transmission testing and reflection testing. Functions of signal source extending, spectrum display and field intensity display are added for the scalar network analyzer. The scalar network analyzer is mainly used for debugging various radio frequency devices, a proper externally-arranged attenuator is added, radio frequency loops of a transmitter and a receiver can be debugged, and field intensity measurement, interference lookup, cable fault lookup and speed factor measurement can be further performed at most of frequency band, and the scalar network analyzer is especially suitable for staged inspection of all parts of a project or a DIY production in a field, operation efficiency can be effectively improved, carrying burden can be reduced, and constriction quality can be improved.

Description

technical field [0001] The invention relates to a network analyzer, in particular to a scalar network analyzer. Background technique [0002] The scalar network analyzer measures the transmission and reflection parameters of the radio frequency network within the frequency range of 10MHz to 2GHz / 2.5GHz / Hz, and can also measure the absolute power of the signal. It is displayed on the screen and can be copied and output by a printer. Can be widely used in communication, television and radar and other fields. [0003] Most of the current scalar network analyzers can only perform signal transmission test and signal reflection test, and the functions cannot be well expanded and extended. Contents of the invention [0004] The object of the present invention is to provide a scalar network analyzer, which expands the functions of signal source, frequency spectrum display and field strength display through the characteristics of the scalar network analyzer itself. [0005] The ...
