A7 Micro-Deck Assembly Overview
Refer to Chapter 13, “Block Diagrams,” for a visual description of the major
blocks of circuitry contained in the A7 Micro-Deck assembly.
The information in this chapter is for the N5173B and N5183B instruments,
which will be referred to as microwave instruments since they have the ability
to operate above 6 GHz.
The part number and serial number used for identifying the A7 Micro-Deck
assembly installed in an instrument can be seen as the MW entry on the
Utility, Instrument Info, Installed Board Info screen, as shown in Figure 11-1.
This part number and serial number is actually the information for the A7A1
Microwave ALC assembly.
