Bit Error Rate Testers (BERT)

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 Rate Tester (BERT) suite, which supports a vast number of different applications including high speed Ethernet rates like 100GbE, 200GbE, 400GbE and 1 TbE.

Multi-Channel NRZ

The BPG & EA 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.

Multi-Channel PAM

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)

The programming capabilities together with the channel synchronization render the BPG + DAC combination to be a full “remote head” AWG at a speed of up to 60 GSymbols/s. More information on this can be found in our dedicated AWG product page.
