Description
The SHF 12110 A and SHF 12122 A are bit pattern generators for applications where cost, space andfunctionalities need to be carefully balanced. They are particularly suited for 40G components, module andsubsystem production tests.
1The units contain a built-in frequency synthesizer to access bit rates from 39.8 to 44 Gbps and allequivalent sub-rate bands of 20, 10, 5 and 2.5 Gbps; therefore rendering them equally valuable as a
general purpose multiple bit rate band data source for a wide range of digital test applications covering thekey bit rate bands from 2.5 to 44 Gbps.

23The devices allow the generation of PRBS signals with pattern lengths of 2 -1, 2 -1, 2 -1, 2 -1, 2 -1, 2 31
1 and 2 -1.
The units are controlled over a standard Ethernet connection by an external computer. An easy to use
software package provides not only a user friendly interface for changing the operating parameters but
also the capabilities of feature enhancement through firmware & software upgrades.
The plug-in version SHF 12110 A is to be used together with the SHF 10000 B and SHF 10001 A
mainframes to allow an individual test setup together with modules from the broad selection of SHF 10000
series extension modules. For production testing up to 4 SHF 12110 A can be combined into onemainframe for multiple device testing.
The stand alone bench top unit SHF 12122 A is a small size unit to be used in the case that no further
extension modules are required.
