InfiniiMax Ultra Series Probes and Accessories

Get Closer to the Truth with the Highest Accuracy Probes

For high-speed digital designers, the InfiniiMax Ultra Series Probes are the most accurate and easiest to use probes. They have the lowest noise and lowest loading for the lowest impact to your circuit. Combined with the super flexible micro probe head, they are the best solution to accurately probe small devices.

See the Truest Representation of Your Signal

When you use a probe to connect your signal to your scope, your probe becomes part of the circuit affecting your test. Your probe may be hiding signal details, loading down your signal, or distorting it. The InfiniiMax Ultra Series Probes have the lowest loading for the lowest impact to your circuit. Boost test margins, make better design decisions, and gain confidence with the unprecedented accuracy. Ensure your entire measurement system is helping you see the truest representation of your signal.

• Compatible with your existing InfiniiMax RC probe heads and accessories

• Measure differential, single-ended, and common mode signals with a single probe tip (InfiniiMode)

Lower Probe Loading Means Better Accuracy

An ideal probe would simply provide an exact replica of the signal being probed. But, in the real world, the probe becomes part of the circuit under test because the probe introduces loading to the circuit. The probe impedance, thus probe loading changes with frequency. To get the most accurate measurements, you want the biggest probe resistance and the smallest probe capacitance across the widest frequency range. The conventional way to model probe loading is to measure the impedance of the probe in a graph of input impedance vs frequency (Figure 1).

The InfiniiMax Ultra Series has an RC input impedance architecture, which has the lowest loading and least signal distortion across the widest frequency range. RC architecture is best for measuring signals that transition to low power (high impedance) modes such as those found in the latest DDR and MIPI standards. The RCRC architecture, found in other probes, is best when higher bandwidth is necessary, or for signals that have low source impedance.

Other Easy-to-Use Features

InfiniiMode

InfiniiMode allows convenient measurement of differential, single-ended, and common mode signals with a single probe tip without reconnecting the probe from its connection point. Benefits include:

• Save setup and connection time

• Use only 1 scope channel

• Reduce errors

Auto-Selected Input Attenuation Ranges

The InfiniiMax Ultra probes have 3 attenuation ranges, 1:1, 4:1, and 8:1 giving you superior noise performance and large voltage ranges all while maintaining maximum bandwidth. Input range is automatically configured depending on the size of the input signal and the vertical scale of the scope. You have three flexible input dynamic ranges to choose from: 600 mVpp @ 1:1, 2.5 Vpp @ 4:1, and  5 Vpp @ 8:1.
