Data Tab:
User selects a test pattern that will be encapsulated in the Ethernet frame payload (for framed mode).
Depending on the test layer, different test pattern options are available.
Layer 1 Framed Test Patterns
CRPAT:
Compliant Random Pattern provides broad spectral content and minimal peaking for the
measurement of jitter at component or system level.
CJTPAT:
Compliant Jitter Test Pattern is a Jitter Tolerance Pattern that stresses a receiver by exposing it to
extreme phase jumps thereby stressing the clock data recovery (CDR) circuitry. The pattern alternates
between repeating low transition density patterns and repeating high transition density patterns.
CSPAT:
Compliant Supply Noise Pattern. Represents worst case power supply noise.
