6. 8133A Training Agenda 2) Operational Overview

7. 8133A Operating Concept • Access to all variable pulse parameters by push buttons and vernier keys • PRBS Hardware generated • 32 bit free programmablememory • All parameters are remote programmable via GP-IB by SCPI commands

8. 8133A Data Generation • Hardware Generated PRBS • based on a 223-1 polynomial • does not use up data memory • 32 bits of Memory Depth • free programmable • by vernier keys to set logical ‘1’ and ‘0’ • Up to 3 GBit/s signal data rate in NRZ or RZ data format

9. 8133A Pulse Period Setting • Period range is 330 ps to 30.303 nsrepresents frequency range from 33.3 MHz to 3.0000 GHz • System clock for single or dual channel instruments • Minimum resolution is 1 ps • Accuracy is ±0.5 % (±0.1 % typical) • External clock mode available, range 33 MHz to 3 GHz • Instrument is not triggerable

10. 8133A Delay & Deskew Setting • When Option 001, 002 or 003 installed • Maximum range for delay & deskew is -5.000 ns to +15.000 ns • Set in reference to the trigger output • Can be set individually for each channel • Minimum resolution is 1 ps • Accuracy is +/- 50 ps • Press delay button twice to enter deskew mode

11. 8133A Width/Duty Cycle Setting • Width range is 150 ps to period - 150 ps • Maximum width setting is 10,000 ps = 10.000 ns • Minimum resolution is 1 ps • Accuracy +/- 100 ps • Duty Cycle is subject to Width and Period, range 0% to 100%

12. 8133A Programmable Output Levels Instrument is over-programmable to achieve the specified amplitude. Amplitude doubles into open circuits.
