DESCRIPTION
The ASNT_PRBS32A can be used for test applications, design verification, and R&Denvironments. The pseudo random bit sequence (PRBS) generator operates from 4Gbps to 32Gbps.
A single-ended half-rate clock is needed to ensure the instrument’s operation. An input frequency of16GHz corresponds to a 32Gbps PRBS data output. The output data is adjustable from 0V to 1.2V
differentially. The trigger output is a user defined divide ratio from 1 to 256. I/O’s are SMA female
connectors with internal AC coupling. All operation and adjustment controls are accessed by a GUI
controlled interface connected through a USB port. Power is supplied with an included AC-DC
power supply.

Front Panel
The front panel of the instrument is shown in Figure 2 with its differential data output, and singleended Trigger output.

Trigger Output
The Trigger Output provides a selectable clock divided ratio with n integer values ranging from 1to 256 with an AC coupled single-ended output amplitude of 600mV. Trigger Output can beconnected to an oscilloscope’s trigger to allow display of a PRBS7 pattern or eye diagram.

Back Panel
The back panel of the instrument is shown in Figure 3 with a single-ended half-rate clock input.
The power ON/OFF switch turns the instrument on and off. The +5V DC power supply (included)connects to the male barrel jack shown in Figure 3. The USB-B connector allows connection to acomputer for controlling the instrument through a Windows GUI.
