Product Overview

The M8049A ISI channel boards can be used to emulate channel loss in receiver test setups. The boards are designed to be used to emulate channel loss for data rates of 32 Gb/s and higher. A choice of 21 PC board traces with different lengths can be inserted into the signal path. The trace lengths range from 0.8 inch (20.3 mm) to 22.3 inch (566.4 mm). By cascading the traces within one board or with another board a wide range of channels can be emulated with very fine resolution of insertion loss steps. With their small size the ISI channel boards can be located closely to the device under test. The cascadable ISI channels are complemented by the Keysight Technologies, Inc. compliance channels for SATA, DisplayPort, PCI Express.

Key Features

Emulate a wide range of channel loss with ISI (Inter Symbol Interference) traces with fine resolution

Three ISI boards with 5 short (1.4’’ to 5.5’’), 9 medium (0.8’’ to 7.95’’) and 7 long traces (9.05’’ to 22.25’’), traces can be cascaded

Rogers 4350B and Megtron 6 PC board material with known S21 parameters

Differential channels

Suitable for symbol rates of 32 Gbaud and higher
