Keysight Technologies N2803A

30 GHz InfiniiMax III Probe Amplifier

The Keysight (formerly Agilent) N2803A is a 30 GHz InfiniiMax III Series probe amplifier. The InfiniiMax III probing system provides the highest bandwidth and incredibly low loading to allow for a completely new level of signal fidelity and accuracy. Four different InfiniiMax III probe amplifiers ranging from 16 GHz to 30 GHz are available for matching your probing solution to your performance and budget requirements. A proprietary 200 GHz fT InP (indium phosphide) IC process with backside ground vias and novel thick film technology is utilized for the InfiniiMax III probe system to accommodate your highest performance needs and is unmatched by any product in the market.

The Keysight (formerly Agilent) N2803A comes with the following specifications:


  • 30 GHz
  • Tr = 14.3 psec


  • DC attenuation ratio : 6:1 (3:1 with 200 ? ZIF tip)
  • Input voltage range : 1.6 Vpp (0.8 Vpp with 200 ? ZIF tip)
  • Input common mode range : ?12 V at DC to 250 Hz, ?2.5 V at >250 Hz (?6 V at DC to 250 Hz, ?1.25 V at >250 Hz with 200 ? ZIF tip)
  • Offset range : ?16 V when probing a single-ended signal

Input Impedance:

  • DC input resistance : R diff = 100 k? ?2%, R se = 50 k? ?2%
  • Input resistance @ >10 kHz : R diff = 1 k?, R se = 500 ?
  • Input capacitance : C diff = 32 fF, C se = 48 fF (with ZIF probe head)
