Bit Error Test & Arbitrary Waveform Generation

BERT for Ethernet, OC-768, CEI, InfiniBand and Fiber Channel

SHF’s Bit Pattern Generators (BPG) or Pulse Pattern Generators (PPG), Error Analyzers (EA) and remote heads form a Bit Error Ratio Tester (BERT) suite, which supports a vast number of different applications including high speed Ethernet rates like 100GbE, 200GbE, 400GbE and 1TbE.
The instruments support up to 8 independent channels broadband from < 10 to 64 Gbps. By combining these instruments with our multiplexer (MUX) and demultiplexer (DEMUX) modules, the serial data rate is extended further up to 120 Gbps per channel.
A PAM source is formed by attaching one of our digital-to-analog-converter (DAC) remote heads to the BPG. This way, the fastest commercially available speed on a single serial coaxial interface (128 GBaud / 256 Gbps) is achieved using our PAM-MUX extender head.
SHF’s capability for true PAM4 BER measurements up to a speed of up to 58 GBaud PAM4 (112 Gbps) is also the industries fastest.

Arbitrary Waveform Generation (AWG)

When it comes to signal generation an Arbitrary Waveform Generator (AWG) is the all-in-one device suitable for every purpose in Telecommunication, Optics, Medicine, Radar, Physics or even Quantum Computing.

NRZ and PAM Pattern Generators (BPG)

SHF’s BPG instruments support a vast number of speeds, signal types and channel configurations. By extending the binary generators with our remote heads the data rate, the number of levels or both is increased. The drop down menus below are supposed to help to find the best fitting instrument configuration for your application.

 

NRZ and PAM Error Analyzers (EA)

By combining the SHF 11104 A EA with a SHF C623 A DEMUX, the serial data rate is extended up to 120 Gbps per channel. The SHF 11220 A PAM-Sampler enhances the capability for true PAM4 BER measurements up to a speed of up to 58 GBaud PAM4 (112 Gbps).

Arbitrary Waveform Generators (AWG)

SHF is offering a cost effective solution housed in a small and light weight chassis (the SHF 19120 C) and a solution based  on our BPG-DAC combination. For PAM signals, it is faster than any other AWG instrument as it samples only one single time per each bit. Thus the baud rate of the resulting PAM signal is as fast as the sample rate of the system.
