Keysight Technologies’ 65-Gsample/sec, 20-GHz modular M8195A instrument will, the company says, deliver a leading combination of bandwidth, sample rate and port density for digital, optical, RF and A/D applications

The high-speed, wide-bandwidth M8195A arbitrary waveform generator allows engineers to generate digital, multilevel (e.g. PAM4 – the screen capture above – and MIPI C-PHY) signal scenarios and test their electrical and optical links with complex modulated signals up to 32 GBaud and beyond.

The instantaneous bandwidth from DC to 20 GHz allows researchers to create extremely short, yet precise pulses.

Developers of radar, electronic warfare, satellite and wireless applications can use the M8195A AWG to create wideband signals up to 20 GHz. The instrument delivers high sample rate and wide bandwidth in combination with industry-leading 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 M8195A 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.
