Embodiment 1

[0024] The switch box (called HRCSF) used for the integrated test of the communication base station, including the box body, the low intermodulation attenuator, the coaxial switch and the power divider, and the main board of the integrated automatic test control module are installed in the box and connected in sequence. There is a circuit connection.

[0025] See attached figure 1 , the front of the box body 1 is equipped with a visual touch screen 2, a test instrument port 3, and a self-locking switch button 4, and there are rectangular cooling holes 5 distributed on the side and top of the box body; the inside of the box body of the present invention adopts a metal main keel with screw holes Armor is used to fix the main support and panel, and the metal auxiliary keel armor with screw holes is used to fix and adjust the internal components. The specific installation method belongs to the conventional means of mechanical installation. See attached figure 2 , There are 8 up...

Embodiment 2

[0031] The switch box used for the integrated test of the communication base station, except that the power divider is replaced by a circulator, is the same as the first embodiment. The NB-IOT uplink signal index of the A port of the base station is tested, and the circulator is used internally to introduce the test. Hardware test switchbox HRCSF steps. Such as Figure 4 As shown, the test unit includes 12 low intermodulation attenuators 11, 3 high-performance coaxial switches 12 and circulators 14 connected in sequence:

[0032] When the A port is selected through the visual touch screen, the signal source outputs any level of NB-IOT signal; the signal passes through the circulator, and then is transmitted to the low intermodulation attenuator through the two-stage high-performance RF coaxial switch for attenuation, after attenuation The signal is transmitted to the A port of the base station to be tested to demodulate the packet loss rate, change the signal source level, repe...

Embodiment 3

[0034] The switch box used for the integrated test of the communication base station is consistent with the first embodiment except that 12 low-intermodulation attenuators are increased to 16. The result of the switch box HRCSF test base station signal is accurate, and the error is less than one thousandth.

Abstract

The present invention discloses a switch box for the integration test of a communication base station. The switch box comprises a low intermodulation signal attenuator, a coaxial switch and a correction device, wherein the above parts are sequentially connected. The correction device comprises a power divider or a circulator. By using the switch box, the to-be-measured FDD signal of the port A of the base station equipment is attenuated by the low intermodulation signal attenuator, and then is transmitted to the correction device through the coaxial switch. Finally, the signal is transmitted to a spectrum analyzer and then a result is outputted. The switch box is optimized in structure, and the requirements of integration, usability, reliability, automation and standardization are met. The switch box also has the functions of effective heat dissipation property, good reliability and the like.

Description

technical field [0001] The invention relates to functional and performance index testing equipment for base stations, in particular to a switch box for integrated testing of communication base stations, which is used for efficient and reliable construction of automated integrated testing systems for FDD LTE and NB-IOT communication standard products. Background technique [0002] With the development of communication technology, in wireless communication, communication networks of various standards are constantly updated. In order to meet people's increasing demand for networks, the technology of the fourth-generation mobile communication system network is also constantly updated. Network communication quality and network coverage have become the main indicators of major operators' competition. [0003] At the same time, a new branch of the new generation of wireless communication technology has emerged on the basis of FFD LTE: the NB-IOT communication system for the Interne...
