John Stoops, Staff Writer
John was born in Greenville, SC in 1947. He graduated from Oklahoma State University in 1970 with a BSEE. He went to work for Bell Labs in Whippany N.J. working on the Safeguard Missile Defense System. Bell Labs sent him to Stanford for his MSEE. John met his future wife, Marie, at Stanford. Marie, a nurse at Stanford hospital, cared for research patients including the first heart transplants in the US. After John had worked for 4 years at the Labs, Bell committed to leaving defense work. John saw an ad for engineers from Tektronix. He applied to Tek and in 1974 was hired into HFCD (High Frequency Component Development). John designed and developed the test and trim fixture for Tek’s NOVAR attenuator. This was used in the SC504. The 1-Megohm attenuator was implemented on a laser trimmed hybrid substrate. The name NOVAR was an abbreviation for “no variables”. The attenuator had laser trimmed the resistors and compensating capacitors. This saved the expense of adjusting the attenuators during manufacturing, and removed the possibility of the attenuator being “misadjusted” by well-meaning but unknowing technicians. It also provided tightly spec’d input R and input C, as well as tightly spec’d divide ratios and “hook-free” compensated attenuators. He transferred into PID (Portable Instrument Division) to work on the Bridge project, which combined an analog scope with a logic analyzer.

John was a hardware project lead for a number of high performance scopes including the 11300A, TDS684, MSO/DPO7000, P6717A, and the DPO70000SX. John had eight patents at Tek.

John retired from Tek in 2017. His interests include music (country, folk, & blues), reading, Scrabble, Trivial Pursuit, computers, forensics, and Christian apologetics. He is easily recognized by his colorful Hawaiian shirts.
