DESCRIPTION
The ASNT_PRBS45 can be used for test applications, design verification, and R&D environments.
The pseudo random bit sequence (PRBS) generator shown in Fig. 1 operates within a wide data
range. A single-ended half-rate clock is needed for the instrument’s operation. An input frequencyof n GHz corresponds to a 2n Gbps PRBS data output. The output data has adjustable amplitude.
The trigger output has a user defined divide ratio in relation to the input high-speed clock. I/O’s are
SMA female connectors with internal AC coupling and CML interface. All operation andadjustment controls are accessible by a GUI connected through a USB port. Alternatively the unit
can be controlled through a DLL. An example python code is provided as one way to use the DLL
to control the unit. Matlab, Java and many other programs can use the DLL. See the user guide formore details. Power is supplied with an internal AC-DC power converter.
