The N2830A Series InfiniiMax III+ probing system is the next generation of InfiniiMax probing, greatly expanding the measurement capability and usability of a probe capable of measuring all components of a differential signal. The built-in InfiniiMode technology allows customers to switch differential, single-ended, and common mode without adjusting probe tip connections.

The N2830A Series probe’s InfiniiMode provides the following modes of operation:

  • A – B (differential)
  • A – ground (signal singled A)
  • B – ground (signal singled B)
  • (A + B)/2 – ground (common mode)

The InfiniiMax III+ works with the full array of InfiniiMax III probe heads and supports the full bandwidth of the InfiniiMax III+.

Probe Soldering Guidelines for Keysight InfiniiMax Probes

Probe Soldering Guidelines for Keysight InfiniiMax Probes

There are various ways to connect test instrumentation probes to devices under test (DUTs). One such method is soldering, which provides a reliable connection and minimizes parasitic probing effects by keeping wire lengths and connections as short as possible. Many of Keysight’s high performance oscilloscope probes utilize soldered connections. As probes and devices continue to shrink, using the correct tools and soldering skills becomes even more critical in order to avoid damage and connectivity issues. This guide provides helpful tips, recommended tools, and techniques specific to Keysight probes to help test engineers make the most out of their soldered-in probes and connections.

Bandwidth Boosting Techniques for the Infiniimax Probe Amp and Probe Head

Bandwidth Boosting Techniques for the Infiniimax Probe Amp and Probe Head

Keysight InfiniiMax differential probes are DSP corrected to have a flat magnitude and phase response to provide the highest possible accuracy. The bandwidth chosen to correct to is typically around 3dB non-corrected bandwidth. Usually, extending the bandwidth much beyond that point will increase the noise floor, and if pushed even further, can cause unrealistic noise artifacts. This application note presents the techniques used to extend the bandwidth performance of the InfiniiMax 1169A/B and the N5381A/B solder-in head using the PrecisionProbe application on Infiniium realtime oscilloscope.
