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) from Keysight Technologies. 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 behaviour in high-speed mobile communication technologies typically deployed in DDR/LPDDR.

Keysight's MX0023A InfiniiMax RC probe provides high bandwidth and low loading, offering up to 25GHz 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 signalling standards such as DDR5/LPDDR5 and other high-speed signal debug and validation test needs.

The RC probe 0ffers probe amp specific S parameter correction filter enabling high accuracy measurements and provides auto-switchable 1:1 and 4:1 attenuation ratio at full 25GHz bandwidth.
