Embodiment Construction

[0021] This application proposes a structure that can be applied to multiple test frequency points and multiple devices under test by using one signal generator, and the required test time is the same as that of the traditional method. In order to make the content of the present invention clearer, the following specific examples are given as examples in which the present invention can actually be implemented.

[0022] figure 1 is a block diagram of a testing device according to an embodiment of the present invention. The testing device 100 includes a signal generator 110 , a controller 120 , a signal distributor 130 and a communication device 140 . The signal splitter 130 is, for example, a splitter. The communication device 140 is, for example, a network card, a WiFi chip, a mobile communication chip, a Bluetooth module, and the like. The signal generator 110 is coupled to a plurality of devices under test. The controller 120 is coupled to the signal generator 110 and the...

Abstract

The invention discloses a test method, a test device and a test system. A controller is matched with a signal generator for testing. The controller respectively receives a plurality of test requests of a plurality of devices to be tested. The controller selects one of a plurality of test frequencies and a plurality of signal intensities included in the test request as a test item, generates notification information based on the test item, and broadcasts the notification information to the to-be-tested device, so that the to-be-tested device including the test request of the test item is subjected to frequency locking. The controller drives the signal generator to generate a test signal corresponding to a test item and transmits the test signal to the to-be-tested device.

Description

technical field [0001] The present invention relates to a test framework, and in particular to a test method, test device and test system. Background technique [0002] As wireless technology keeps changing, RF (Radio Frequency, radio frequency) testing has become a daily routine for engineers in the mobile communication industry. For mobile terminal equipment, test time is an important factor, so the industry is constantly looking for ways to reduce test time and related costs. Generally speaking, when testing the Rx function of the device under test, multiple frequencies and signal strengths need to be tested, for example, high frequency / low energy, intermediate frequency / high energy, low frequency / high energy, etc. [0003] There are two traditional methods of testing. The first test method is to use three signal generators to simultaneously send high-frequency signals, intermediate-frequency signals and low-frequency signals to the device under test (DUT), so that the ...
