Keysight Introduces MX0023A InfiniiMax RC probe for DDR5/LPDDR5

  • Keysight Technologies announced the MX0023A InfiniiMax RC, a new high speed differential probing solution for Double Data Rate 5 (DDR5) and Low Power Double Data Rate 5 (LPDDR5).

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 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.
The Keysight MX0023A InfiniiMax RC offers users the following key benefits:

  • Delivers 25 GHz bandwidth with an RC input impedance topology for low mid-band probe loading.
  • Enables today’s emerging signaling standards including: LPDDR/DDR5, MIPI bus signaling and other high-speed signal debug and validation test needs.
  • Offers probe amp specific S parameter correction filter enabling high accuracy measurements.
  • Provides auto-switchable 1:1 and 4:1 attenuation ratio at full 25 GHz bandwidth.
  • Support for Keysight’s broad variety of probe heads and InfiniiMax I/II accessories.
  • AutoProbe II interface for direct connection to Keysight’s Infiniium Series Oscilloscopes.
