Application Examples
InfiniBand EDR (25.78G) AOC Evaluation
8ch (4ch two ways) Simultaneous BER Measurement
QSFP Active Optical Cables (AOC) used by InfiniBand, etc., perform
simultaneous transmission over a total of 8 channels using two-way
transmissions over 4 channels. The MP1900A incorporates 8 channels
(8ch PPG + 8ch ED) simultaneously in one main unit and can measure
all channels at one time, offering excellent performance and shorter
measurement times. Moreover, InfiniBand HDR measurement is also
supported using PAM signals.
Jitter Tolerance Test
AOCs in data centers are using low input and output amplitude levels
to cut power consumption costs, making it important to assure
interconnectivity. With its high sensitivity data input and CTLE, the
MU195040A supports reception of low-amplitude, low-Eye-opening
Data signals and perform high-reproducibility DUT Jitter Tolerance
tests.
Crosstalk Effect Confirmation
Implementing 20 Gbit/s class transmissions not only requires logic tests
but also requires actual equipment verification tests. Since the
MP1900A has both pattern synchronization and independent phase
tuning for each channel, tests on items such as the effect of AOC
crosstalk are implemented easily.
Bathtub Jitter and Eye Diagram Analysis
Bathtub Jitter Analysis (separate TJ, RJ, DJ) is supported by the built-in
as standard Clock Delay function. Low bit error rates, such as 1E-12 and
1E-15, can also be estimated quickly from the change in bit error rate
versus phase.
