Abstract

The invention relates to a radio frequency measuring method, which belongs to a method for measuring a radio frequency element by adopting a radio frequency measuring system consisting of a network analysis instrument, a radio frequency switch and a control computer. According to the radio frequency measuring method, when a network analysis instrument is used for scanning each frequency point of one port of a radio frequency switch, a control computer is used for synchronously reading a measuring value of each frequency point measured in a last port through scanning by the network analysis instrument, and meanwhile, the control computer is used for synchronously processing the data of each frequency point measured in the last port by the network analysis instrument and outputting the data so that the time for the radio frequency measuring system to cyclically measure all ports for once is greatly shortened. The radio frequency measuring method has the advantage that the time for the radio frequency measuring system to cyclically measure all ports for once can be greatly shortened.

Description

The radio frequency method for measurement

Technical field

The present invention relates to a kind of radio frequency method for measurement, performance (for example: method parameters such as reflection coefficient and penetrating coefficient) to be mainly used in measurement RF component (for example: antenna, filter, amplifier etc.).

Background technology

The technology of radio frequency extensively applies to various radio communication products at present, comprises mobile phone, digital television broadcasting, wireless Internet access, satellite navigation etc., produces huge and far-reaching influence to the mankind's life; Interpersonal distance is shortened in the application of mobile phone; Digital television broadcasting can at any time teleview people, gets online without being tethered to a cable to make people can receive and dispatch message whenever and wherever possible, and satellite navigation provides the driver clearly road message; Make tourism more convenient, these application make the human lives convenient more.

Any radio communication product all has different radio frequency element (for example: antenna, filter, amplifier etc.) to undertake difference in functionality; (for example: quality parameters such as reflection coefficient and penetrating coefficient) has absolute relation to the performance of integral product to the RF component performance, so RF component all must measure before use; The purpose that radio frequency measures, whether up to specification, can bring into play its performance in use if promptly being to measure the RF component performance, reach the best target of radio communication.

Radio frequency measurement system as shown in Figure 1, present is to comprise by network analyzer 10, RF switch 20 and 30 of controlling computer to form; Wherein, This RF switch 20 has some measurement ports (P1~P16); Its motion flow in the time will measuring the element under test 40 of certain port (for example: antenna); Controlling computer 30 can switch to the port that this desire measures with RF switch 20; For example: in the time will measuring the element under test 40 of port P3, controlling computer 30 can switch to port P3 with RF switch 20, and then being given an order by controlling computer 30 requires network analyzer 10 scannings to be positioned at each Frequency point of the element under test 40 of port P3; Read network analyzer 10 scannings by controlling computer 30 then and be positioned at each measured Frequency point measuring value of port P3, last scanning by controlling computer 30 processing network analyzers 10 again is positioned at each measured metric data of port P3 and output result.

Above-mentioned existing radio frequency measurement system though RF switch capable of using 20 increases the quantity that measures port, to save the expense of buying network analyzer 10, reaches the purpose that increases tested productivity; But; As shown in Figure 2; Because the handling process of above-mentioned existing radio frequency measurement system; Be when controlling computer 30 switches to measurement port P (n) with RF switch 20; Its will be in regular turn completion comprise each Frequency point, controlling computer 30 that network analyzer 10 scannings are positioned at the element under test 40 of port P (n) read each measured Frequency point measuring value of network analyzer 10 scanning port P (n), controlling computer 30 handle measured each of network analyzers 10 scanning port P (n) measure according to and after the output result waits all operation programs, switch to another port P (n+1) again and proceed due measurement operation program; Therefore, its shortcoming is that the measurement processing speed of total system is slow, makes the frame updating that measures figure too slow.

Hold above-mentionedly, P (n) is meant the measurement port when step n, and P (n+1) is meant the measurement port of the next step n+1 behind step n.

Summary of the invention

Technical problem underlying to be solved by this invention is, improves above-mentioned existing radio frequency measurement system and is measuring the existing shortcoming of handling process, and a kind of radio frequency method for measurement is provided, and it can significantly shorten the radio frequency measurement system and once circulate whole port times of measurement.
