Optical Receiver Stress Test Solution
N4917B
-
The N4917B software provides an automated standard compliant stressed receiver sensitivity test according to 100GBASE-LR4, ER4 and SR4 test specification. In order to do this kind of test, several test instruments such as a bit error ratio tester, digital sampling oscilloscope, optical reference transmitter and tunable laser source are required to operate together to achieve a compliant, repeatable optical stressed eye. This stressed eye is then fed to the receiver under test, where bit error ratio is measured under the stress conditions as defined in the standard.

Universal Transmitter
Model LXT-330
-
Teledyne Analytical Instruments
Model LXT330 Liquid Transmitter is a single or dual channel, universal, multi-parameter transmitter, designed for continuous online liquid measurements. It is paired with SP3 Smart sensors and is intended for use in non-hazardous, general purpose rated industrial environments. The SP3 sensor platform covers a wide range of liquid analytical measurements, such as pH, ORP, Specific Ion (pION), dissolved oxygen, free chlorine, total chlorine, conductivity, resistivity and turbidity. The LXT330 transmitter can be used with any SP3 smart sensors without additional user reconfiguration. The Universal Transmitter & Smart Sensor loop philosophy removed the need to stock for multiple instrument types. The process parameter, sensor details, serial number and calibration history are stored in the sensor's main memory, facilitated by two-way digital communication between the sensors and transmitter. The LXT330 universal transmitter allows for up to two SP3 sensors per transmitter (contact factory for available combinations).
