Test Pattern PRBS: 2^7–1, 2^9–1, 2^15–1, 2^23–1, 2^31–1
Auxiliary pattern: 1/2 Clock Pattern, 1/16 Clock Pattern
Pattern Invert ON/OFF
External ATT Factor 0 to 30 dB, 1 dB resolution
Able to display the relative value of Data output and Data output.
Error Addition Single
*1: These are measured in the MP2110A sampling scope (with
MP2110A-024).
The clock output is used for the external trigger (Trigger) of the
sampling scope.
*2: These can be output separately.
*3: When bit rate is set to 25.78125 Gbit/s.
*4: When amplitude is set to 0.3 Vp-p.
*5: These are measured in 25±5 degree Celsius.
*6: Test pattern is PRBS 2^31–1.
*7: Test pattern is 1/16 Clock Pattern.
