High-speed differential probes handle DDR5, LPDDR5 memory signals

The MX0023A InfiniiMax RC is a new high-speed differential probing solution for Double Data Rate 5 (DDR5) and Low Power Double Data Rate 5 (LPDDR5) memory.

As data rates of mobile bus systems increase, the edge speed of the signal gets faster, thus requiring higher bandwidth probe solutions. At the same time, many systems deploy a continuously variable termination mechanism, switching the termination impedance between low and high impedance, to save power consumption in devices. This requires a higher speed probing solution with high input impedance profile over wider frequency range for low probe loading. This is common signal behavior in high-speed mobile communication technologies typically deployed in DDR/LPDDR.

Keysight’s new MX0023A InfiniiMax RC probe provides high bandwidth and low loading, offering up to 25 GHz bandwidth and an RC input impedance profile for extremely low mid-band loading, which is necessary to address modern high-speed probing requirements. It also provides a wide variety of flexible connectivity solutions, covering today’s emerging signaling standards such as DDR5/LPDDR5 and other high-speed signal debug and validation test needs.

To ensure that Keysight Infiniium oscilloscope customers have access to the right probes and accessories for their applications, Keysight offers a wide selection of high-quality probes and accessories. The newest addition to this growing selection of probes is the Keysight MX0023A InfiniiMax RC, which offers customers the following key benefits:
