Abstract All Personal Computer (PC) and Server manufacturer's developmental units utilize test equipment to validate their designs and Oscilloscopes are one of the more important tools needed. However, the four channel Agilent Technologies Infinum Oscilloscope has a very specific shortcoming. The probe design requires manual placement and when four channels are utilized, placement by hand is impossible. The most common solution is to solder gold connectors or wires to the Device Under Test (DUT) . Other solutions involve duct tape and rubber bands. This presents multiple problems: Waveform misrepresentation, extended time consumption, and inconsistent measurements. The correct solution is to construct a base to hold the DUT and a multi-jointed probe holder that allows direct probing while freeing up the Technicians/Engineers hands to perform other necessary measurement tasks. Introduction Utilizing the Agilent Technologies Infinium Oscilloscope on computer busses requires adroit technical and mechanical dexterity. A full understanding of external circuit loading along with the ability to maintain positive contact with the DUT ensures accurate measurements. The majority of bus protocols require qualifying signal measurement to verify the signal under test is a valid signal. These measurements can require
