Arbitrary waveform generator enables multi-level signal scenarios

A 92GSa/s, 32GHz modular instrument has been added to its portfolio of arbitrary waveform generators by Keysight Technologies. The high-speed, wide-bandwidth M8196A arbitrary waveform generator allows engineers to generate digital, multi-level (e.g., PAM-4, PAM-8, DMT) signal scenarios at 8 bits vertical resolution and test their electrical and optical links with complex modulated signals up to 64GBaud.

The M8196A supports leading edge research for 100Gb/s, 400Gb/s and 1Tb/s communication applications.

The arbitrary waveform generator supports high-speed and coherent optical transceiver and component testing with its four synchronized channels in one instrument, allowing deterministic emulation and predistortion of two independent I/Q signals.

It will also support R&D tests in the development of new physical layer standards exceeding 100Gb/s with the instrument’s unmatched flexibility which also allows de-embedding of a channel’s S-parameters, in-situ calibration and signal stress conditioning and the generation of any mathematically defined arbitrary waveforms, ultra-short yet precise pulses and multiple GHz chirps.

The instrument offers up to 2 Vpp differential output voltage and adjustable DC offset in a -1 to 2.5V window and 8 bits vertical resolution and rise and fall times below 9ps.

The M8196A runs on a 1-slot AXIe modular system designed for high-performance instrumentation.
