The HP/Agilent 54622D is a 2+16 channel mixed-signal oscilloscope delivering simultaneous acquisition of analog and digital signals up to 100 MHz bandwidth. Built for engineers analyzing complex embedded systems, digital interfaces, and multi-protocol designs, this instrument combines 2 analog channels with 16 digital logic channels in a single platform.
