Problems solved by technology

[0005] Although the electronic calibration module realizes the automation of calibration, for multi-port calibration, such as 16-port calibration, the calibration process still needs to spend more time for connection and measurement
Secondly, the impedance standard inside the electronic calibration module is affected by the hardware, and will deviate from the factory calibration value with use, so it usually needs to be re-calibrated once a year

Embodiment Construction

[0041] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0042] A two-port electronic standard structure such as figure 1 shown.

[0043] 1. Straight-through error model (such as figure 2 shown)

[0044] When the electronic calibration module is directly connected between port i and port j, the above error model can be obtained. Then the relationship between the measurement parameters and the error term and the true value of the electronic calibration module can be obtained:

[0045]

[0046]

[0047]

[0048]

[0049] Among them, S iiM , S ijM , S jiM , S jjM is the S parameter measured for ports i and j; S ii , S ij , S ji , S jj is the true value of the S-parameter of the electronic calibration module through; is the error term between port i and the electronic calibration module; is the error term between port j and ECal module.

[0050] 2. Single-port error acquisit...

Abstract

The invention, which belongs to the technical field of calibration, discloses a rapid calibration method based on an electronic calibration component. Measurement of a non-starting port is reduced, the dual-port calibration speed is nearly doubled, and the multi-port downloading speed is increased substantially. Because reduction of measurement of the impedance state of the electronic calibrationcomponent of the non-starting port, setting of the impedance state of the electronic calibration component is reduced, the service life of the electronic calibration component is prolonged, and the manual operation error occurrence is reduced. Extending to an N port for calibration is realized.

Description

technical field [0001] The invention belongs to the technical field of calibration, and in particular relates to a fast calibration method based on an electronic calibration component. Background technique [0002] Electronic calibration technology is an emerging automatic calibration technology for vector network analyzers, which is used for automatic calibration and error correction of vector network analyzers. It is characterized by automatic calibration, small size, light weight, USB power supply mode, and high calibration accuracy.
