Remote sampling head modules

31 October 2012 Test & Measurement

Agilent Technologies introduced a 60 GHz remote sampling head oscilloscope module for engineers who design, validate and manufacture high-speed electrical communications systems and components.

The N1045A 2/4-port module provides an economical solution for accurately characterising multilane designs used in today’s new and emerging standards such as IEEE 802.3 ba/bj/bm (40Gb/100Gb Ethernet) and Optical Internetworking Forum CEI 3.0.

Users can configure up to four N1045A modules in a single Agilent 86100D DCA-X wide-bandwidth oscilloscope mainframe to create a system with 16 channels.

The popularity of smartphones, tablets and online video content continues to drive the need for faster network connections. Increased network performance is enabled through multiport serial interfaces operating at 28 Gbps and up. Testing high-speed, high-port-density components and systems usually requires an expensive configuration of multiple oscilloscopes and complicated switching that compromised signal integrity.

But the 86100D DCA-X mainframe, configured with one to four N1045A modules, provides a 2- to 16-electrical-channel measurement system that is both economical and accurate. By combining the N1045A with the 86107A precision time-base module, users can create an 8-channel 60 GHz system with an ultra-low 200 fs rms time-base jitter. This is ideal for efficiently testing a quad differential port device operating at 25 to 28 Gbps.

Each low-noise sampler is located at the end of a flexible 1,6 m cable to minimise cable loss and ensure high signal fidelity. With a selection of bandwidth settings (60, 45, 35 or 20 GHz) and independent sampler skew control, the N1045A allows users to optimise the receiver for the device under test.

The light, small remote heads allow the samplers to be positioned in very tight locations. To minimise the use of adaptors, the modules can be configured with 1,85 mm male or female connectors.
