A new Phase Reference Module has been released by Tektronix, Inc. The company’s 82A04B is designed for its DSA8300 oscilloscope and when combined with new electrical sampling modules provides instrument jitter of <100 femtoseconds. The instrument offers characterisation of critical 100G transmitters and links on up to six channels as defined in the IEEE802.3ba & 32G Fibre Channel test specifications. For designers working on 100 (4×25) Gb/s communications systems, a key test challenge has been acquiring high bit-rate signals with sufficient fidelity to allow precise characterisation of the device under test in the presence of real-world signals. As clock speeds continue to increase, the bit period at 25Gb/s is just 40 picoseconds, making it critical to minimise instrumentation jitter and noise while providing enough bandwidth to fully characterise signals. The instrument can support simultaneous acquisition of up to three differential signals.
