Anritsu Corporation is pleased to announce the release of upgraded high-load Jitter Tolerance test functions for the company's MP1800A Signal Quality Analyzer series to support evaluation of devices for high-speed serial transmission, including 100GbE, OIF-CEI 28G, InfiniBand EDR, and 32G Fibre Channel.

The MP1800A is a plug-in modular type Bit Error Rate Tester (BERT); installing a jitter generation module supports generation of various jitter modulation components, including SJ, RJ, BUJ, SSC, 2nd Tone SJ, etc.

This newly released function generates up to 2000UI wide-amplitude SJ . At high jitter modulation frequencies of 250 MHz, SJ generation supports up to 1UI. In addition, using the newly released Equalizer compensate Eye-opening of signals output from devices under test (DUT) degraded by transmission path losses, and supports BER measurements.

These new feature enable configuration of measurement systems with sufficiently high accuracy and margin for Jitter Tolerance tests of devices such as SERDES supporting 100GbE, OIF-CEI 28G, InfiniBand EDR, 32G Fibre Channel, etc.

With its extremely low intrinsic jitter of just 275 fs rsm (norminal) at the zero jitter setting, the MP1800A Jitter Modulation Source module supports accurate measurements even at the lowest jitter amplitudes. Furthermore, with a low-intrinsic-jitter Pulse Patter Generator (PPG), 4TAP Emphasis, PAM Converter, High-Accuracy Error Detector (ED) and Automatic Jitter Tolerance measurement software, the MP1800A is the ideal total solution for Jitter Tolerance measurements.

Development of high-speed serial devices is progressing due to the explosive increase in data traffic, faster processing speeds of servers and network equipment, and faster communications speeds between equipment. By releasing these extended Jitter Tolerance measurement functions, Anritsu expects to help with deployment of faster servers and network equipment.

 

[Development Background]

The rapid growth of cloud computing services is driving explosive increases in traffic volumes at data centers. As a result, new, high-speed communications protocols, such as 100GbE (100GBASE-SR4, KR4, CR4), InfiniBand EDR, and 32GFC, are being examined due to the need to support increasing server and network equipment processing speeds as well as faster communications speeds between equipment. Jitter Tolerance is a key index of the receiver characteristics of PHY devices such as SERDES used by these high-speed serial communications. Since Jitter Tolerance requirements rise in line with increasing bit rates, there is an urgent need for test that can measure receiver Jitter Tolerance both accurately and with sufficient margin. Furthermore, the output signal of the DUT is degraded by losses in the transmission path, reducing the size of the EYE opening and sometimes preventing reception by the measuring instrument ED.

Anritsu’s MP1800A Signal Quality Analyzer series is already a popular Jitter Tolerance measurement solution for high-speed devices up to 32 Gbit/s and with this new release of upgraded functions it can now generate wide-amplitude SJ up to 2000UI and 1UI at high jitter modulation frequencies of 250 MHz. Furthermore, Anritsu has also simultaneously released an Equalizer function for compensating the EYE opening of the signal output from the DUT and supporting BER measurements in combination with a high-accuracy ED. 

 

[Product Outline]

The MP1800A Signal Quality Analyzer series is a plug-in modular-type BERT in which PPG, ED, synthesizer, and jitter generation modules can be installed simultaneously.

This newly release of upgraded functions it can now generate wide-amplitude SJ up to 2000UI and 1UI at high jitter modulation frequencies of 250 MHz along with simultaneous generation of RJ, BUJ, SSC, and 2nd Tone SJ.

It can be used to configure a high-accuracy measurement system with sufficient margin for measuring the Jitter Tolerance of PHY devices such as SERDES supporting 100GbE, OIF-CEI 28G, InfiniBand EDR, 32G Fibre Channel, etc.

And with a low-intrinsic-jitter PPG, 4TAP Emphasis, PAM Converter, High-Accuracy ED, Equalizer function for EYE opening compensation, and Automatic Jitter Tolerance measurement software, the MP1800A is the ideal all-round test solution for Jitter Tolerance measurements.

This newly released function is enabled by the MP1800A software version 7.9 and later, used in combination with the MU181500B Jitter Modulation Source unit.

 

[Product Features]

■ Simultaneous SJ, RJ, BUJ, SSC, 2nd Tone SJ Generation

Simultaneous generation of SJ, RJ, BUJ, SSC, and 2nd Tone SJ at high bit rates of 32 Gbit/s is supported, meeting the requirements of the OIF-CEI 28G, 100 GbE, InfiniBand EDR, 32G FC, etc., standards.

■ High-Amplitude SJ Generation

Generation of up to 2000UI wide-amplitude SJ. 1UI at high jitter modulation frequencies of 250 MHz offers sufficient margin for device Jitter Tolerance limit measurements.

■ Low Intrinsic Jitter

The Jitter Modulation Source with an extremely low intrinsic jitter of just 275 fs rms (norminal) at the zero jitter setting, supports accurate measurement even at the lowest jitter amplitudes.

■ EYE Opening Equalizer Compensation

The EYE opening of output signals from DUT tends to become closed as a result of higher bit rates and losses in the transmission path, sometimes requiring an Equalizer at the measurement receiver to open the EYE. Inserting a passive-type linear Equalizer upstream of the ED compensates for the transmission path losses to restore the EYE opening. Combined use with a high-sensitivity ED supports Jitter Tolerance tests of PHY devices with a narrow opening.

■ High-sensitivity ED

An independently developed Anritsu wideband, high-accuracy receiver chip achieves high accuracies of 10 mV (typ., single-end, EYE height).

■ Built-in Clock Recovery

The built-in Clock Recovery function supports TRx asynchronous SERDES Jitter Tolerance tests.
