Alan Wolke, W2AEW, Senior Applications Engineer for Tektronix Corporation, visited ARRL Headquarters in Newington, Connecticut on January 6, 2015 to introduce the ARRL Laboratory Engineers to their new Tektronix Mixed Domain Oscilloscope, model MDO4104B-3, which is being donated to the ARRL by Tektronix.

Alan, an ARRL Life Member, arranged for the donation. The dual function instrument has a bandwidth of 1 GHz, 5 GS/s for time domain measurements and can make frequency domain measurements up to 3 GHz. The MDO4104B-3 replaces the ARRL Lab's Tektronix TDS-3052B, a 500 MHz storage oscilloscope. This new addition substantially upgrades the Lab's measurement capabilities.

Bob Allison, WB1GCM, ARRL Test Engineer, said, “This oscilloscope is a huge benefit to us. It will be particularly important considering the fast paced evolution of digital technology. The ARRL Lab is grateful to Tektronix, to Alan Wolke, and Tektronix Public Relations Manager, Amy Higgins, for this generous contribution.”

It is interesting to note that Alan has personally produced a large number of quality training videos. Each video is a valuable tool for the radio amateur who wishes to learn more about the many practical applications of test instruments.
