1. GENERAL INFORMATION
1-1. INTRODUCTION
The Model 7040A shown in Figure 1-1, is a 40 MHz dual-trace oscilloscope with
many quality features: wide bandwidth, high sensitivity, dual timebases with
delayed sweep, and a TV sync separator. Moreover, the large CRT has an illumin­
ated internal graticule for parallax-free measurements and photographic applications.
