Key Features & Specifications

Compatible oscilloscopes:

  • Infiniium 9000 Series


The N2903A is no longer available for purchase from Keysight. However, this product is supported if the instrument already has a Win XP COA (certificate of authenticity). If you are working in a secure environment, you will need to send a backup removable HD used for cals and repairs. If you do not have a spare removable HD to send, remove the secure HD from the cartridge and send the empty cartridge with the scope. The service center will then install a replacement HD, and complete the repair and cal.

If you need an additional removable hard drive, upgrade your oscilloscope to Win 7 (with option N2754A) and order N2745B
