Model 12070 Clock Output and Data Output Descriptions

Picosecond Pulse Labs utilizes bit stretching and user programmable clock divisors to provide many user benefits and the highest possible performance.

User benefits include an extremely broad range of user programmable data rates (30Mb/s to 30Gb/s) and highly flexible clock output rates.

The Model 12070 pattern generator incorporates a high performance YIG oscillator clock design to achieve very low random jitter (~200fs). This clock source operates over an octave (factor of 2) from 15GHz to 30GHz. This approach was chosen to minimize performance degradation from low slew rate signals and amplitude noise. To create patterns at data rates below 15Gb/s, the internal pattern generator module automatically employs bit stretching. This simplifies instrument use with either PRBS or user data (user programs the data rate, pattern generator decides and applies a bit stretch factor to achieve that data rate).
