Item Description

Keysight / Agilent M8048A-001 Four Short ISI Channel Loss Emulator for M8020A BERT

 

 
You are bidding on a Keysight / Agilent M8048A-001 Four Short ISI Channel Loss Emulator for the M8020A BERT. This unit is in excellent condition, has been fully tested and is guaranteed functional. 
 
The M8048A ISI Channels can be used to emulate channel loss in receiver test setups. A choice of 8 PC board traces with different lengths can be inserted into the signal path. The 8 trace lengths range from 7.7 inch (196 mm) to 34.4 inch (874 mm). By cascading the traces within one box or with the other box a wide range of channels can be emulated with very fine resolution steps. With their small size the ISI channels 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®, and HDMI. 
 
Emulate Channel Loss
 
The channel loss between transmitter and receiver is a critical element for the receiver test for all electrical multi gigabit serial interfaces. The channel loss depends primarily on the distance between transmitter and receiver and the electrical medium. The channel loss is typically defined by the S21 parameter in dB for certain frequencies. Some standards define the receiver test to include a certain channel loss in the test setup. M8048A offers a wide range of cascadable channels to emulate certain S21 parameter conditions in a repeatable and accurate way. 
 
Emulate Intersymbol Interference 
 
Low-cost Nelco FR4 PC board material is very commonly used in many consumer and computer products. Long electrical cables are also very common (HDMI, DisplayPort and USB) for connecting consumer and computing devices. With increasing bit rates the signal degradations caused by the channel become a critical part for the receiver characterization and compliance test. The so-called intersymbol interference (ISI) caused by the channel degradation is a data dependant jitter or a bounded deterministic jitter. The ISI jitter added by a PC board trace not only depends on the trace length and the PC board material, but also depends on the data rate and the transmitted bit pattern. The ISI jitter a receiver must tolerate is typically defined in ps or mUI by each standard for the required bit rate and compliance pattern. 
 
This unit is in excellent condition, has been fully tested and is guaranteed functional. It comes w/ a 14 day right of return should it not perform to your expectations.
