Chip testing apparatus and system with sharing test interface
A chip testing apparatus and system suitable for performing testing on multiple chips in a chip cluster are provided. The chip testing apparatus includes a signal interface and a test design circuit. The signal interface transmits an input signal and multiple driving signals in parallel from a test equipment to each of the chips. The test design circuit receives multiple output signals from the chips through the signal interface and serially outputs a test data to the test equipment according to the output signals.
Test arrangement for adjusting a setup of testing a device under test, a method of operating the test arrangement, and a non-transitory computer-readable recording medium
A test arrangement for adjusting a setup of testing a device under test (DUT) includes a main device that generates an RF signal and processes an incoming RF signal in a first frequency range; a frontend component generates an RF signal and processes an incoming RF signal in a second frequency range. The frontend component measures a signal level in a sub-range within the first frequency range; a connection cable connects the main device with the frontend component; and an analyzer predicts a behavior of the connection cable in a rest portion of the first frequency range that is different from the sub-range within the first frequency range.
