Slow clock test method for mobile communication terminal and test system thereof

Abstract

The invention relates to the field of the mobile communication terminal, and discloses a slow clock test method for a mobile communication terminal and a test system of the slow clock test method. The slow clock test method comprises the following steps that in a period that USB (universal serial bus) connection between a test host and the mobile communication terminal is switched on, the test host is used for operating the mobile communication terminal through the USB connection according to a test case; after the USB connection between the test host and a mobile communication terminal to be tested is cut off, the test host is used for judging whether the mobile communication terminal to be tested enters a sleep mode or not; after the mobile communication terminal to be tested enters the sleep mode, a current value provided for the mobile communication terminal to be tested from a programmable constant current supply is obtained, and a slow clock test result of the mobile communication terminal is judged according to the obtained current value. Due to the fact that the current value provided for the mobile communication terminal to be tested from the programmable constant current supply is read in the test, current test precision can be improved. Due to the fact that the mobile communication terminal is operated by the test host via the USB connection, working efficiency is improved.

Description

technical field

[0001] The invention relates to the field of mobile communication terminal testing, in particular to a mobile communication terminal slow clock testing method and a testing system thereof. Background technique

[0002] The slow clock test is to test whether the current entering the sleep mode after operating each functional module is less than the required milliampere. The purpose is to use this indicator to control the power consumption of each module when entering sleep mode. The conventional method is the black box test, which manually clicks on each module, waits for the mobile communication terminal to go to sleep, and waits for the current to stabilize, then records the standby current and average current of the mobile communication terminal, but it takes a lot of manual time to pass the black box test. The current is stable, and the test accuracy is not high, and the test result may be wrong due to misoperation and other reasons. Contents of the inv...
