81133A Pulse Pattern Generator, 3.35 GHz, single channel - 1

Figure 1: 81134A Agilent Technologies 81133A and 81134A 3.35 GHz Pulse Pattern Generators Data Sheet Version 1.2 81133A and 81134A 3,35 GHz Pulse Pattern Generators Setting Standards The Agilent 81133A and 81134A 3.35 GHz Pulse Pattern Generators provide programmable pulse periods from 15 MHz (66.6 ns) to 3.35 GHz (298.5 ps) on all channels. With frequency ranges this fast, the transition time performance becomes critical; the Agilent 81133A and 81134A perfom at less than 60 ps tansition. With a RMS jitter of 1.5 ps (typ), the best signal quality is assured. The Delay Control Input and the Variable Crossover Point functionalities allow fast and easy Signal Integrity measurements, including emulation of real world signals by adding jitter to clock or data signals or by distorting the 'eye' for eye diagram measurements. Key Features The need for pulse and pattern generation is fundamental to digital device characterization tasks. The ability to emulate the pulse and pattern conditions to which the device will encounter in its final application, is essential. This emulation should include both typical and worst case conditions. Accurate emulation requires superlative signal integrity and timing performance along with full control over parameters that allow specific worst case testing. · Pulse, Data Pattern and PRBS generation from 15 MHz up to 3.35 GHz · Data formats NRZ, RZ and R1 · 12 Mbit pattern memory per channel · Low jitter, high accuracy · Fast transition times · PRBS generation from 25 - 1 …231 -1 · Delay control input for pre-defined jitter input · Jitter emulation up to ± 250 ps · Easy- to-use graphical user interface · 50 mV to 2 Vpp output amplitude · Differential Outputs · 1 or 2 channels

3 Frequency/Period The main frequency is set for all channels. The frequency can also be set as period length. The frequency range is 15 Hz to 3.35 GHz, equal to 66.6m to 298.5 ps period. The frequency range can also be further divided individually for each channel. Available dividers are 1, 2, 4, 8, 16, 32, 64, 128. Main Modes Pulse Pattern Mode In Pulse Pattern mode, each channel can be set independently to one of the channel modes described in 'Channel Modes'. Burst Mode Burst mode enables the output of a burst consisting of data repeated n times followed by continuous zero data. It can...

Agilent Technologies 81133A and 81134A 3.35 GHz Pulse Pattern Generators 4 Timing Delay The delay can be set: · as an absolute value in nano seconds or pico seconds. The delay remains unchanged as the frequency or the period is modified. · as phase (degrees relative to period). The phase remains unchanged as the frequency or the period is modified. Deskew The deskew adjustment allows for the compensation of e.g. cable delays. Deskew adjustment is not available in Direct Mode. In this case, all channels are factory deskewed at the front panel connectors. Width There are two ways to set the...
