Table 10: 3.4 Gb/s Signal Generator: output specifications

1) Voltage window direct at module output is -2 V to +3.5 V; DC power supply needed with Bias Tee. For output voltage

> 3 V the termination voltage > 3 V needs to be applied

2) Measured with E4808A clock module, spec as intra channel jitter

Specification assumptions

The specifications in this data sheet describe the instrument’s warranted

performance. Non-warranted values are stated as typical (typ.).

All specifications are valid from 10 °C to 40 °C ambient temperature after a

30 minute warm-up phase, with outputs and inputs terminated with 50 Ω to

ground at ECL levels if not specified otherwise.
