Rev.
C
Logic symbols (gates) are used, if they represent more appropriately, in a
simplified form, the logic function performed even by complex parts of
hardware.
Where necessary, functional description of power supplies and minor
assemblies are referred to schematic diagrams.
NOTE
The schematic block diagrams of Chapter 3 show all the
functions that the boards’ hardware could potentially support,
while the related functional description refers only to the
functions implemented in the present customized configuration.
3.2
Functional Description
On the basis of the SRT X-BAND RARAR SYSTEM functional block diagram
shown in Chapter 9, Figure 9.1.7, the equipment can be subdivided into the
following main assemblies:
−
Electronics Rack
−
RF Head
−
Brushless Motor Controller
−
Motor Unit
There are also a number of optional functions which are also described below,
as:
•
The SRT Adapter Box
•
Heaters
•
Encoder
3.2.1
Electronics Rack
The Electronics Rack block diagram is shown in Chapter 9, Figure 9.1.7 and
Figure 9.1.8. Each block represents a functional area which is described in
detail in the following function of the present chapter (paragraphs 3.3 through
3.7). The blocks indicated by dotted lines represent circuits assembled on the
equipment chassis.
This is concerning all the blocks diagrams of this chapter.
Basically, the unit performs the following functions:
−
it generates the power supply voltages required for the unit’s functioning
−
it generates the R.F. pulses which will be radiated by the Antenna; the
pulses, in X-band wave length (9375 ±30 MHz for NJRC or 9410 ±30
MHz for EEV Magnetrons) and with 12 (10 for EEV Magnetrons) or 25
kW peak nominal power, can be selected among the following:
