The Keysight MX0023A InfiniiMax RC probe provides high bandwidth and low loading, offering up to 25 GHz bandwidth and RC input impedance profile for extremely low mid-band loading necessary to address modern high-speed probing requirements. 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 back and forth between low and high impedance in order to save power consumption in devices. This is common signal behavior in high-speed mobile communication technologies typically deployed in DDR/LPDDR and MIPI. The Keysight MX0023A 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.

Each individual InfiniiMax RC probe amplifier contains its own frequency response data. As with the InfiniiMax III and III+ probe amp, the unique s-parameters of the InfiniiMax RC probe amp are stored in the probe amp and are used with the s-parameters of the various probe heads to further flatten the magnitude and phase response of the probe for high accuracy measurements.

A proprietary ASIC technology is utilized for the InfiniiMax RC probe to accommodate the highest performance needs and is unmatched by any product in the market. The technology enables an auto-switchable 1:1 and 4:1 attenuation ratio of the probe for superior noise performance while maintaining the maximum 25 GHz bandwidth. At a 1:1 attenuation ratio, the probe provides 25 nV/√(Hz) of excellent spectral noise density referred to the input of the probe, which is comparable to the market-leading InfiniiMax II 1169B/68B probes.

Keysight’s InfiniiMax RC probe supports a wide variety of high-speed probing applications with an extensive line-up of probe heads and accessories. Continuing the probe head topology pioneered by Keysight in the InfiniiMax I and II probe systems, three new probe heads are provided to accommodate multiple use models. The MX0100A and MX0106A offer an exceptionally wide operating temperature range of -55 °C to +155 °C, making them ideal for environmental testing of a wide variety of highspeed devices.
