Probe meets DDR5 and LPDDR5 says Keysight Technologies

High speed differential probing from Keysight Technologies includes a differential probe for Double Data Rate 5 (DDR5) and Low Power DDR5 (LPDDR5). The MX0023A InfiniiMax RC has been introduced as higher bandwidth probes are required in response to the increase in data rates of mobile bus systems. Keysight points out that 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.

The MX0023A InfiniiMax RC probe provides high bandwidth and low loading, offering up to 25GHz bandwidth and an RC input impedance profile for low mid-band loading, to address modern high-speed probing requirements. It also provides a variety of flexible connectivity solutions, for emerging signalling standards such as DDR5/LPDDR5 and other high-speed signal debug and validation test needs.

The MX0023A offers a probe amp-specific S parameter correction filter enabling high accuracy measurements, says Keysight, and provides auto-switchable 1:1 and 4:1 attenuation ratio at 25GHz and also supports Keysight’s variety of probe heads and InfiniiMax I/II accessories.

Other probes and accessories available include the MX0105A differential SMA head and MX0106A differential solder-in head.
