5.1 INTRODUCTION
This section provides information for testing, calibrating,
and trouble shooting the sweep generator. The performance
test
i s
designed for incoming inspection and periodic evalua-
tion.
I f performance is not to specifications, refer t o the
calibration and trouble shooting sections.
5.2 SERVICE INFORMATION
5.2.1 DISASSEMBLY INFORMATION
Figure 5-1. Disassembly
REMOVAL OF BOTTOM COVER - Remove the two rear
feet ( A ) and l i f t cover off with a slight rear movement.
REMOVAL OF TOP COVER - Remove the single screw
(6)
from the top and l i f t off cover with a slight rear move-
ment.
REMOVAL OF SIDE PANEL - Either side panel can be
removed to provide better access by removing the four
screws holding the side panel to the instrument. The Front
Panel/Module Section can be removed from the power
supply section by removing two screws holding the sec-
tions together and by disconnecting the electrical connec-
tors between the two sections.
NOTE:
The separation of
the two sections performs no useful purpose during normal
service procedures.

MODULE SERVICING
SERVICE K I T K 102
-
This service k i t contains a module
extender and RF extension cables which enables the module
to be electrically operated while physically located above
the rest of the modules, thereby making all parts easily
accessible.
REMOVAL OF MODULE - Modules may be removed by
removing any cables attached to the top of the module and
removing the hold-down screw ( C ) from the bottom.
REMOVAL OF MODULE COVER - Remove all nuts and
screws from the top of the module and slide the cover off.
REINSTALLING MODULE
-
Before reinstalling the
module, check the module pins for proper alignment, then
carefully seat the module pins into the chassis socket and
replace the hold-down screw ( C ) to insure a good ground
connection between module and chassis.
MODULE PIN NUMBERING SYSTEM - The module
pins are numbered as shown in Figure
5-2.
The index studs
for the circuit modules are located off center t o prevent
the module's being plugged in backwards. This off-center
stud location also provides a method for locating pin $1.
