Example Embodiment

[0028] The invention utilizes a radio frequency switch to realize automatic switching of the test channels of the two formats during the dual-mode terminal test calibration, and can avoid the problems of time wasting and low production efficiency caused by manual operation in the prior art. At the same time, the present invention uses the comprehensive tester as the test instrument, which can realize the calibration and testing of two systems, and reduces the cost of the test instrument.

[0029] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings:

[0030] Referring to FIG. 1, it is a schematic diagram of the structure of the dual-mode terminal calibration test device of the present invention. The calibration test device of the dual-mode terminal of the present invention includes:

[0031] A set of radio frequency switch 1 and its logic control device 2 are used to control the radio frequency switch 1 th...

Abstract

The apparatus comprises: a RF instrument used for testing the terminal. Said terminal comprises two RF ports and a RF switch; one end of the RF switch is connected to the one of two RF ports; the other end of the RF switch is connected to the RF instrument. The invention used for realizing the automatic switchover between the calibration testing channels when making a calibration test of two systems.

Description

technical field [0001] The invention belongs to the field of wireless terminal calibration and testing, and in particular relates to a radio frequency calibration and testing device and method for a dual-mode terminal. Background technique [0002] The dual-mode portable terminals currently on the market include GSM and PHS dual-mode terminals, CDMA and GSM dual-mode terminals, TD and GSM dual-mode terminals, WiFi and GSM dual-mode terminals, etc. These dual-mode terminals enable a terminal to It can be used on different networks to meet the needs of users for different services. However, the calibration and testing of these dual-mode terminals basically use one set of equipment for each mode, and the dual-mode terminal needs to occupy two sets of test equipment for RF indicators in different modes, which increases the cost of testing, increases labor costs, and reduces calibration, Test efficiency. [0003] Take the TD-SCDMA and GSM dual-mode dual-standby terminal as an e...
