Level: TTL
Impedance: 75Ω (non-equilibrium)
9) Error Test
Bit error (8K/ 16K/ 32K/ 64K/ 128K/ 256K/ 512K/ 1.024M/ 2MB/s): Detect PRBS and programmable character graphics gradually
10) Graphic Synchronization
Synchronization loss: If error rate > 5× 10-2 namely, synchronization loss is generated.
Synchronization obtaining: > 100ms error-free, namely, synchronization is obtained.
11) Error Display Mode
Error counting (EC)
Method: The total error within the measured time. Display: When the counting number is over 99999, display automatic switch as index (XXXXEXX) mode, the maximum counting could read 9.999E13.
Seconds Error Rate (SER)
Method: The ratio between the total error and corresponding total clock in 1s. Display: X. XXXE-N (X. XXX × 10-8)
12) Warning Display
There are three kinds of warning displays, including no signal, full 1 warning, error warning
13) Measurement Cycle
