PCIeDisplay Card Tester


When repairing Display Card,we need to judge if there is any GPU contact issue.PCIe Display Card Tester is designed to detect this kind of failure quickly. Combining with Multimeter, repairer can identify the issue quickly. This PCIe Display Tester uses dedicated PCIe test chip, and use LED to show the test result, and the precise is 100%.
 
Five Main Features: 

1.Use USB port to provide power, and no extra power supply is needed.
2.Use specified PCIe test chip, and it is 100% precise
3.70 LED indictors, and cover most of PCIe signals)
  TX00+ to TX15+(16PCS); TX00- to TX15- (16PCS); RX00+ to RX15+(16PCS); RX00- to RX15-(16PCS); RSTJ, PCLK+, PCLK-,12V, 3.3V, 3VAUX
4.Use one key to test, and easy to use
5.Optimze LED arrangment, and it is easy to find corresponding pin
