The Keysight E8257D is a fully synthesised signal generator that provides high output power and low phase noise, as well as powerful modulation capabilities. Unless otherwise noted, the instrument achieves these specifications over a temperature range of 0 to 55 °C and after a 45-minute warm-up. Supplementary characteristics (labelled Typical, Nominal or Measured) provide additional (non-guaranteed) information about the instrument at 25 °C and may be useful in product applications.

The Keysight M8199B is an arbitrary waveform generator with a sample rate of up to 246 GSa/s and an analogue bandwidth of over 50 GHz. It supports up to eight synchronised channels, each equipped with 1 MSa waveform memory and built-in frequency and phase response calibration. The device is aimed at R&D engineers, providing a high-performance source for arbitrary signals, enabling them to develop designs including, but not limited to, multilevel modulation formats (e.g., 64QAM) at 150 GBaud and above.

The Keysight M8199B Arbitrary Waveform Generator (AWG) is a high-performance signal source designed for R&D engineers to support the development of advanced designs at rates of up to 160 GBaud and above. The device is capable of sampling up to 256 GSa/s over up to eight simultaneous channels, with an analogue bandwidth of over 80 GHz. Built-in frequency and phase response calibration functions ensure the purity of the output signal.

The Clock Recovery Device (CDR: Clock and Data Recovery) is a very critical component in a communication system. Its main function is to extract clock information from the received signals in order to sample and retime the data correctly. This process is critical to ensure the accuracy and reliability of data transmission.

With the proliferation of fixed-rate video streaming and cloud services, data traffic is exploding. As a result, deployments of 100 GbE, and even 400 GbE and 800 GbE networks require optical interfaces for transport devices that support speeds above 10 Gbit/s. However, the demand for low-cost optical interfaces is increasing due to the critical issue of how to increase production line productivity while reducing costs.
The BERTWave MP2110A is an all-in-one instrument with built-in BERT (Bit Error Rate Tester) and sampling oscilloscope (Eye Diagram Pattern Analysis) for inspection and analysis during the manufacturing process of 10G to 800G optical modules. It helps to increase production line productivity and reduce costs.

The Keysight N1077B is an optical/electrical clock recovery device that supports a data rate range of 115 MBd to 24 GBd for multimode and singlemode optical signals as well as electrical signals. The device is capable of handling both PAM4 and NRZ data signal types and provides standards-compliant clock recovery.The N1077B features adjustable peak and loop bandwidths (up to 10 MHz), which enables it to provide optimised performance in a variety of application scenarios.

The N1092D is a high-performance DCA-M sampling oscilloscope manufactured by Keysight for use in optical communications. With four optical channels and supporting 28/45 GHz bandwidth, the device is suitable for testing and analysing high-speed data transmission.

The main difference between the Keysight N1092D and Keysight N1092C is the number of optical and electrical channels they have. The Keysight N1092D is a sampling oscilloscope with four optical channels, while the N1092C is equipped with one optical and two electrical channels. In addition, from the technical specifications, the N1092D has an optical channel bandwidth of 28 GHz (characteristic value) and supports a wide range of factory-calibrated wavelengths, such as 850 nm, 1310 nm and 1550 nm.
