Theory of Operation
This chapter describes the basic structure of the oscilloscope and how the parts interact.
The 90000 Q- Series oscilloscopes are comprised of five or six main assemblies, depending
on the model of the oscilloscope: a motherboard assembly, an acquisition assembly, a
backplane assembly, an oscillator assembly, and a front panel assembly for all models,
plus a RealEdge Technology Assembly for 50 GHz and 62 GHz bandwidth models. Each
oscilloscope also has a bulk power supply.
Figure 7- 1 shows a block diagram of the Q- Series Infiniium oscilloscope.
