2. Differences and Functional Characteristics of Diagnostics & Stability-Test
Cards and Common Analyzer Cards
(1) The Diagnostics & Stability-Test Card is a kind of high performance card by
which not only the PC failure but also its stability can be tested.
(2) By PC Diagnostic Cards, the hardware problems can be found easily. It helps us
to find the causes when the computer works abnormally. No matter you are a
developing engineer, a maintenance man or a beginner, or a common user, it
shows the PC failures and helps your make rapid and correct treatment.
(3) The Diagnostics & Stability-Test Card is mainly used for stability test. It can test
not only the stability of the stable computers, but also stability of the unstable
computers, not matter it is invariable failure or variable failures, such as
occasional and invisible potential failures.
(4) It is helpful for PC and PC accessory selection. It can help users select the high
quality computer and spare parts (such as memory bank, hard disk and key
board), even the external equipments (such as UPS, printer and computer
used for ATM), and help the seller to sell the stable computers at a good price.
(5) Independent of the RESET signal of the test computer, the abnormal reset logic
of the testing computer will not influence the testing. There are also functions
such as automatic failure correction and automatic preventing pulse loss.
Reset the computer during testing will not influence the stability test.
(6) The CLK indicator Diagnostics & Stability-Test Card has been thoroughly
upgraded, it’s 100% correct and will not mislead the users. The users can see
the clock pulse fluctuation clearly, even the single 10ns clock pulse. CLK light
will not be on when there is no CLK signal impulse, no matter the current
signal stays at high or low level. No pulse loss, no unwanted pulse.
