9.1 INTRODUCTION
The RFL 9300 display module (93B DISPLAY), shown in Figure 9-1, serves as the user interface to the RFL

ters can be set by keyboard entries while the RFL 9300 is in the PROGRAM mode.
Each display module contains three main assemblies (See Table 9-1). The display controller board is described
below, the oscillography board is described in paragraph 9.3 of this section, and the front panel assembly is de-
scribed in paragraph 9.4 of this section.
