It is possible to create digital and multi-level (PAM-4, PAM-8, DMT) signal scenarios with high resolution.

Keysight Korea has added a 92-GSa/s, 32-GHz modular device to its arbitrary waveform generator product family.

With the new high-speed, wideband M8196A arbitrary waveform generator, engineers can create digital, multi-level (PAM-4, PAM-8, DMT) signal scenarios with 8-bit vertical resolution and test complex modulated signals and electrical and optical lines up to 64 GBAud*.

The M8196A is the industry's fastest and most versatile signal generator, optimized for cutting-edge research and development for 100Gb/s, 400Gb/s, and 1Tb/s communication applications. Additionally, it enables high-speed coherent optical transceivers and component testing via four synchronous channels in a single device, as well as deterministic emulation* and predistortion* of two independent I/Q signals.

With the device's excellent flexibility, which enables in-situ calibration, signal stress conditioning, and de-embedding of channel S-parameters, it supports R&D testing for developing new physical layer standards exceeding 100 Gb/s. It is also possible to generate mathematically defined arbitrary waveforms, precise ultrashort waves, and multi-GHz chirps.

The M8196A precisely tunes up to four signals simultaneously in a 1-slot AXIe module with an analog bandwidth of 32 GHz and a maximum sample rate of 92 GSa/s. It also provides a differential output voltage of up to 2 Vpp, an adjustable DC offset from -1 to 2.5 V, 8-bit vertical resolution, and rise and fall times of less than 9 ps. The M8196A, a 1-slot AXIe module type, is an arbitrary waveform generator optimized for high-performance systems.

* GBaud(gigabaud): Giga Baud (Baud)
* Baud: A unit representing the transmission speed of a signal. It is expressed as the number of units (bits) of telegraph code that can be sent per second.
* Deterministic emulation: This is an emulation based on simulation in which a fixed relationship is given between the input variable and the output result for each action, value, or event so that the result for a given input variable is always the same.
* Predistortion: A technique to improve the linearity of communication transmission amplifiers.
* In-situ correction: Self-correction
* S-parameter: A parameter of the 4-terminal network model that defines the operation of waveguides and transistors in the microwave region.
* Chirps refer to the continuous change in the frequency of light over time.
