Probes measure differential, single-ended, and common-mode signals

Test & Measurement World Staff - July 22, 2012

Three InfiniiMode active differential probes from Agilent Technologies are useful tools for digital system design, component design and characterization, and differential serial bus measurements. The N2750A series probes offer bandwidths of 1.5 GHz, 3.5 GHz, and 6 GHz and work with the company’s Infiniium oscilloscopes.

InfiniiMode probing allows engineers to make differential, single-ended, and common-mode measurements with a single probe tip without reconnecting the probe to change the connection. The N2750A probes also feature built-in multifunction scope control for quick access to a variety of scope functions.

All three models in the series provide 2:1 and 10:1 attenuation settings. The attenuation range is automatically configured, depending on the size of the input signal. With input resistance of 200 kΩ (differential), input dynamic range of 10 V pk-pk, and high common-mode rejection ratio of >60 dB at 1 MHz, the probes can be used for a wide variety of analog signal measurements, as well as digital design and debugging.

Prices for the N2750A (1.5 GHz), N2751A (3.5 GHz), and N2752A (6 GHz) probes are $3800, $5100, and $6300, respectively.
