Display Pan el
Touch Panel
Processor (μATX) Board
The active-mat display has a 1024 x 768 resolution and brightness is set to full intensity.
For AWG5000C Series instruments, the display is controlled by the Processor board. For AWG5000B Series instruments, the display is controlled by the MIO board (or the display adapter board on AWG5000B Series instruments with serial numbers B020000 and above).
The touch information from the touch screen is processed by Windows drivers, actively p lacing the pointer at the touched location. Actions from the mouse and the touch panel are interchangeable, and treated alike by the user interface software. The AccuTouch resistive touch screen uses a glass panel with a uniform resistive coating. A thick polyester coversheet is tightly suspended over the top of a glass substrate, separated by small, transparent insulating dots. The coversheet has a hard, durable coating on the outer side and a conductive coating on the inner side. The controller is located on the LCDA board.
The μATX board provides standard Windows functionality and I/O port interfaces on the rear panel. This includes RS-232, Parallel, and Ethernet ports, as well as four USB ports, plus two USB2.0 ports located in the lower right front corner of the instrument. The μATX board receives input from the front panel and touch panel, and implements the appropriate changes. For AWG5000C Series instruments, video display data is transferred through the LVDS co AWG5000B Series instruments, video display data is transferred through PCI bus interface. The hard drive is connected to the μATX board through the SATA interface, and the CD/DVD is connected to the Windows system through the IDE parallel interface.

Power Supply
Secondary Power Supply
Fans
The CD/DVD drive is connected to the Windows via an interface connector on the μATX board. AWG5000C Series models connect using the SATA interface. AWG5000B Series m odels connect using the IDE parallel interface.
The power supply is a switching AC to DC converter. It automatically detects the line voltage over the range of 90 to 264 VAC. It supplies power to all the circuitry in the instrument. No switch completely disconnects the line power from the instrument. The ON/STBY switch controls the power to the instrument through the μATX board circuitry. When in the “power off” condition, there is still a low power standby current to allow the system to monitor the ON/STBY switch.
The secondary power supply is a switching AC to DC converter. It automatically detects the line voltage over the range of 85 VAC to 265 VAC.
Three fans on the side of the instrument provide forced air cooling. The fans are controlled by the fan speed control circuit on the PWR board and are regulated by monitoring the temperature at the circuitry.
