Trigger Inputs
4 RSA5100A Series Service Manual
There are two coaxial trigger inputs. One is on the front panel below the display
and the other is on the rear panel. Both trigger inputs connect directly to the
Digital Interface board. Trigger signals are processed by an FPGA on the Digital
Interface board. The information from the trigger system is combined with
acquisition data by the processor system.
The Trigger Out signal is a coaxial connection on the front panel below the
display. The trigger out signal comes from the Acquisition Control FPGA,
through the Digital Interface board.

The touch panel is listed as a USB HID device in the Window Device Manager
tool.
The processor system de tects changes in the front-panel switches and encoder. The
processor also turns the LEDs on and off. Communication between the processor
system and the front panel is performed over an internal USB connection.
The ON/STBY switch passes through the display adapter board, the PC carrier
board, the digital interface board, and to the PC board.
The DVD-RW and removable HDD (hard disk drive) communicate over a SATA
connection directly to the processor system.

General Purpose Interface Bus
The Power Conversion board provides instrument power. The Power Conversion
board consists of several switching supplies that translate and b alance the power
taken from the power supply module.
Power is distributed from the Power Conversion board to both the RF Deck and
the Digital Interface board.
The ON/STBY switch, located on the front panel, controls all of the power to the
instrument except for the part of the circuitry in the standby power supply.
Fans
Several fans provide cooling to the RSA:
Three fans are located in the RF Deck and are controlled by the RF Interface.
Two fans provide cooling for the Digital Deck of the instrument.
The Power Supply module has an internal fan.
The COM Express PC board has a fan that is controlled by the COM Express
PC board.
The optional DPSA board contains a fan.
