Arbitrary waveform generator targets digital, RF applications

A high-speed, wide-bandwidth M8195A arbitrary waveform generator that allows engineers to generate digital, multilevel (e.g. PAM4, MIPI C-PHY) signal scenarios and test their electrical and optical links with complex modulated signals up to 32 GBaud and beyond has been unveiled by Keysight Technologies.

The 65-GSa/s, 20-GHz modular instrument offers instantaneous bandwidth from DC to 20 GHz that allows researchers to create extremely short, yet precise pulses. Developers of radar, electronic warfare, satellite and wireless applications can use the instrument to create wideband signals up to 20 GHz.

It delivers high sample rate and wide bandwidth in combination with port density. This unique functionality allows engineers to make reliable, repeatable measurements when they are working on binary and multilevel, multichannel digital interfaces as well as coherent optical and wideband communication applications.

The waveform generator uses out-of-the box and in-situ calibration and signal predistortion methods to generate exceptionally clean signals – even at the highest data rates. Engineers also can use these techniques to embed or de-embed the channel between the generator and the device under test. The implementation in hardware allows change of parameters at runtime.

With up to 16 GSamples of waveform memory, the instrument allows designers to create long and highly realistic signal scenarios. Multiple modules can be combined in a system with up to 16 fully synchronous channels in a single 5-slot AXIe chassis.
