AUX signal and 4 Lane signals, dual-mode dp switch by DP signal switching apparatus, several DP signal inputs, DP delivery outlet,
HDMI delivery outlet composition, passes through the middle line signal of corresponding port between dual-mode dp switch and DP signal-testing apparatus
Connection；DP exports the DP delivery outlet signal of port transmission, the HDMI delivery outlet signal of HDMI delivery outlet can switch dress with DP signal
Bi-directional is set, 5 class signals in signal source can be directly passed to DP signal switching apparatus；There are one for DP signal-testing apparatus
There are double mode CAD signal testing route B, DP a signals for a double mode HPD signal measurement circuit A, DP signal-testing apparatus
There are a double mode AUX signals to survey there are double mode CEC signal testing route C, DP a signal-testing apparatus for test device
Route D is tried, there are a double mode 4Lane signal testing route E for DP signal-testing apparatus.
Entire dual-mode dp signal switching automatic testing equipment test switching signal has 5 classes: HPD signal, CAD signal, CEC
Signal, AUX signal, 4 Lane signals support double mode-DP mode and HDMI mode, the signal source of 5 class signal kinds to pass to
DP signal switching apparatus in dual-mode dp switch, can be converted the DP delivery outlet of double mode DP delivery outlet signal,
The signal of the HDMI delivery outlet signal of HDMI delivery outlet, both of which can be transferred to DP signal by corresponding middle line
Test device, at this moment, double mode HPD signal measurement circuit A, double mode CAD signal testing route in DP signal-testing apparatus
B, double mode CEC signal testing route C, double mode AUX signal testing route D, double mode 4Lane signal testing route E difference
5 class signals are carried out with the detection of on-off and quality, later, signal is transmitted to by corresponding to the middle line of DP signal input
Dual-mode dp switch thus constitutes the circulation that a signal can switch and detect between double mode.
Technical solution usefulness provided by utility model device: the equipment can cooperate DP signal-testing apparatus certainly
The on-off and signal quality of dynamic test DP input and each signal in output interface, can support maximum video resolution 3840
× 2160@60HZ, improve labor efficiency and other purposes, enhanced products market applicability.
