The gasket is equipped with a surrounding portion and an extending portion. The surrounding portion is sleeved on the port while the extending portion is extended from one side of the surrounding portion. The stabilization of the measuring port is achieved by applying the gasket and a fastening mechanism. The measuring port product as least has technical advantages of stable port, easy measurement, and increased measured precision.
Description
Technical field
The utility model relates to a kind of measurement port of network analyzer.
Background technology
Network analyzer is a kind of new instrument of measuring network parameter, can directly measure the plural scattering parameter of active or passive, reversible or irreversible twoport and one-port network, and provide amplitude, the phase-frequency characteristic of each scattering parameter with sweep method.Automatic network analyzer can carry out error correction to the measurement result pointwise, and converse other tens kinds of network parameters, such as transformation parameter and isolation and degree of orientations etc. such as input reflection coefficient, output reflection coefficient, voltage standing wave ratio (VSWR), impedance (or admittance), decay (or gain), phase shift and group delays.
For example, a kind of existing network analyzer utilizes a six-port network that is comprised of directional coupler and hybrid juction as measuring unit, and except two ports connect respectively signal source and the measured piece, all the other four ports are all received magnitude demodulator device or power meter.By the appropriate combination of four amplitudes detecting, can obtain mould and the phase place of tested network scattering parameter.It needn't obtain phase information with the two-channel receiver of complexity, thereby the hardware of measuring system is greatly simplified.In addition, it has the redundant measurement port that surpasses essential number, can utilize the credibility of checking mutually to improve measurement result between the redundant data.But its evaluation work is more more complex than four port network analysers.Adopt Dual-six-port network analyzer to measure two-port network, namely be connected on the port one of tested network with a six-port network instrument, another is connected on port 2, can in measuring process, avoid switch transition or manually reverse input end and the output terminal of tested network, further improve the degree of accuracy of measuring.
But the test port of existing network analyzer is easily loosening, makes troubles to test, and affects measuring accuracy.For example, the port mouth of instrument sometimes can become flexible, and loosening relatively severity, and sometimes the user need to be fixed it, but does not additionally add thing, does not fix at all.Loosening is the problem of instrument internal screw design, and the pad of screw is too soft, and when instrument was new, port was substantially not loosening, will rock too large after instrument has been used of a specified duration.
The utility model content
Based on the demand of prior art, the utility model proposes a kind of measurement port of network analyzer, comprising:
The port pedestal is fixed on the described stabilizing network analyser;
Port, described port are arranged at described port pedestal; And
Pad is placed on the described port,
Wherein, described pad has encirclement section and extension, and described port entangles in described encirclement section, and described extension extends to a side from described encirclement section.
According to a preferred embodiment of the present utility model, in the measurement port of above-mentioned network analyzer, described port be shaped as circle.
According to a preferred embodiment of the present utility model, in the measurement port of above-mentioned network analyzer, the described extension of described pad is two extension rods, and described two extension rods all extend from a side of described port pedestal.
According to a preferred embodiment of the present utility model, in the measurement port of above-mentioned network analyzer, also comprise: retention mechanism is arranged between described two extension rods and the position of the side of close described pedestal.
The utility model makes test port stable by loading a pad and retention mechanism.Therefore, measurement port product of the present utility model has the technical advantage that measuring accuracy is stablized, is convenient for measuring, is improved to port at least.
Should be appreciated that the above generality of the utility model is described and the following detailed description all is exemplary and explanat, and be intended to provide further explanation for as claimed in claim the utility model.
Description of drawings
Accompanying drawing mainly is be used to providing the utility model further to be understood.Accompanying drawing shows embodiment of the present utility model, and plays the effect of explaining the utility model principle with this instructions.In the accompanying drawing:
Fig. 1 schematically shows the viewgraph of cross-section of the measurement port of network analyzer of the present utility model.

Embodiment
Describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
Fig. 1 schematically shows the viewgraph of cross-section of the measurement port of network analyzer of the present utility model.As shown in the figure, the measurement port 100 of network analyzer of the present utility model mainly comprises: port pedestal 101, port one 02, pad 103 and retention mechanism 104.
Wherein, port pedestal 101 is fixed on the described network analyzer.Port one 02 is arranged on the described port pedestal 101.For example, port one 02 can be arranged at the centre of pedestal, and port one 02 circular port normally, but port of the present invention is not limited to this, but can be any type of port known in the art.In addition, pad 103 is placed on the described port one 02.
Particularly, Fig. 2 schematically shows an embodiment of pad.
As shown in Figure 2, pad 103 of the present utility model has encirclement section 105 and extension 106, and described port one 02 entangles in described encirclement section 105, and described extension 106 extends to a side from described encirclement section 105.
According to a preferred embodiment of the present utility model, in the measurement port 100 of above-mentioned network analyzer, the described extension 106 of described pad 103 is two extension rods, and described two extension rods all extend from a side of described port pedestal 101.
In addition, as shown in Figure 1, retention mechanism 104 is arranged between described two extension rods and the position of the side of close described pedestal 101.
According to the utility model, when becoming flexible appearred in test port after long-time the use, the user can outwards stretch the extension 106 of pad 103, and then is undertaken fastening by the pad 103 behind 104 pairs of drawns of retention mechanism, thereby allow to fix test port, make it stable.
The utility model makes test port stable by loading a pad and retention mechanism.Therefore, measurement port product of the present utility model has the technical advantage that measuring accuracy is stablized, is convenient for measuring, is improved to port at least.
Above-described embodiment provides to those of ordinary skills and realizes or use of the present utility model; those of ordinary skills can be in the situation that do not break away from utility model thought of the present utility model; above-described embodiment is made various modifications or variation; thereby protection domain of the present utility model do not limit by above-described embodiment, and should be the maximum magnitude that meets the inventive features that claims mention.
