r 1 t i Communications Nancy Thomas, HP Stanford Park Diu. Ask a service engineer or technician what training they need and you're likely to hear, "We need measurement and applications training." If you think about it, the request makes sense. Understanding the environ- ment that instruments operate in is a valuable addition to one's trouble- shooting tool kit. Hewlett-Packard has developed an c interactive training program aimed at new technical entrants in the field of digital microwave communications. If you or your group is involved in servicing microwave communications equipment, you'll want to order a copy of the HP 11736A I-& Tutor, a digital microwave communications tool. 4 Structured Like a Laboratory Workbench -t t 10; I-& Tutor is educational software ' with a manual, and is designed to be used with the popular HP 9000 Model 216 or Model 236 computers.
