Front Panel
The front panel consists of an aluminum case panel (part of the R&S FSP frame) and a mounting plate
which accommodates the LCD, the backlight inverter, the keyboard mat with the membrane and the
spinwheel. The case panel incorporates the front-module controller
LCD
The color LCD provides a visible output of any information, measurements etc. to the user. The
resolution of the LCD is 640 * 480 pixels (VGA).
The display incorporates a cold cathode tubes for the illumination. The high voltage required for this
purpose is generated in an extra DC/AC converter mounted next to the display on the mounting plate
and connected both to the display and the controller board via a cable.
Keyboard
The keyboard consisting of a keyboard mat and a membrane release a contact when the rubber key is
pressed. Two LEDs for the STANDBY/ON key (orange for STANDBY/green for ON) are also
accommodated on this membrane.
The key evaluation and LED control are effected via a film cable connector on the controller board. Like
the control of the two LEDs, it is controlled in a special microprocessor on the controller board by means
of a matrix technique. This microprocessor permits to store the status of the STANDBY/ON key when
switching off using the power switch.
Front module controller
The front module controller contains all the necessary components on a board such as processor,
memory chips (SIMM modules), I/O devices (ISA bus) lithium battery, IEC-bus controller (IEEE), two
serial interfaces (COM1/2), a parallel interface (LPT), LCD graphics controller, external VGA monitor
graphics interface (monitor) and an external keyboard connection (keyboard PS/2).
In addition, a floppy controller for an external floppy disk drive and an SATA hard disk controller are
integrated on the controller board.
Hard disk
The hard disk is screwed to the rear of the aluminum case panel and connected to the printed circuit
board via two cables.
Removable hard disk (Option R&S FSP-B18)
A removable flash disk can be installed in the instrument instead of the hard disk by means of option
R&S FSB-B18. The option is installed instead of the floppy disk drive. The compact flash board contains
a connector for a compact flash cards of type 1 and a connector for establishing the connection to the
SATA interface of the front-module controller.
Flash Disk (Option R&S FSP-B20)
A flash disk can be installed in the instrument instead of the hard disk by means of option R&S FSB-
B20. The compact flash board contains a connector for a compact flash cards of type 1 and a connector
for establishing the connection to the SATA interface of the front-module controller.
