InfiniiMax II Series Probe Amplifier
With the Keysight 1168B (10 GHz) and 1169B (12 GHz) probes, you can probe differential and single-ended signals. The probes provide a large common mode range for measuring differential signals and a large offset range for measuring single-ended signals. These probes are used at extreme frequencies where off-board lead resistors cause undesirable response variation. As a result, the 1168B and 1169B probes were designed using resistor-at-the-tip technology where resistors are located on the very edge of the probe tip board. The wires or probe tips in front of the resistors are long enough to allow the easy connection but are short enough that any resonances caused by them are out of the band and don't impact the input impedance.
With only a 3.4:1 attenuation ratio, the Keysight 1168A, and 1169A provide the lowest probe noise floor among InfiniiMax probes, making them ideal for signal integrity measurements that require high sensitivity. The Keysight 1168A and 1169A probing systems support a wide variety of real-world applications with an extensive lineup of probe heads and accessories. InfiniiMax probe accessories support browsing, solder-in, socketed, ZIF tip, QuickTip (magnetic tip), soft touch head and SMA head solutions with various options to choose from.
Extensive Variety of Probe Heads and Accessories
Keysight’s InfiniiMax II probes support a wide variety of real-world applications with an extensive line-up of probe heads and accessories. Please see below and the accessories tab for details. Six different InfiniiMax II probe heads can be used including a Zero Insertion Force (ZIF) probe head that uses a ZIF tip that can be installed at many locations on your DUT. The ZIF tip’s small size is critical in probing tight locations and the ZIF feature allows connection without compressing the delicate wires which cannot support this compression.
