Product description

The Tektronix PPG4001 PatternPro® programmable pattern generator provides an unparalleled combination of industry leading performance, features, and ease of use. Design validation of today’s demanding high-speed applications requires instruments that produce the highest quality signals and enable programmable controls while being simple and easy to use.

Fast rise time and low jitter are critical performance parameters and the PPG4001 delivers typical 150 fs inherent RJ with 11 ps rise time. Within seconds of powering up the instrument, a first time user can be creating high-performance programmable patterns to test a DUT. In addition, the PPG4001 offers comprehensive jitter insertion for stressed receiver testing and similar applications.

The PPG4001 may be paired with the PED4001 40 Gb/s programmable error detector to provide a complete BERT system that includes control and analysis software.

Specifications

All specifications are guaranteed unless noted otherwise. All specifications apply to all models unless noted otherwise.

Data outputs

Voltage amplitude

Each positive and negative differential output is independently programmable.

Single-ended: 300 mV to 1.0 V
Differential: 600 mV to 2.0 V

Offset window: -2 V to +3.3 V, programmable/adjustable

Termination voltage range

-2.0 V to +3.3 V window. Programmable/adjustable. Applied by user via 50 Ω.

This setting is used in cases where the load being driven is terminated at a level other than zero volts. The effect of termination voltage on the output voltage is shown in the following figure. To ensure proper operation, never load the output with a termination voltage less than Voh minus 3 V.
