Module Overviews

Theory of Operation

A Microsoft Windows processor system is the primary controller of the instrument.
The instrument features an XGA resolution flat-panel display, a transparent touch
screen, and a front panel with direct access to commonly used instrument
functions. You can also make complete use of the instrument with a mouse and a
keyboard.

Front Panel (FP) Board

LCD Adapter (LCDA) Board

Push-button switches on the Front Panel (FP) board are read by an embedded micro
controller, which sends the button and knob change information to the μATX bo ar d
via a USB path. The FP board consists of the following blocks:

 USB controller (Cypress EZ-USB FX1)

 FPGA (Altera Cyclone)

 Key switch matrix

 LED indicators (Tri-Color and Mono-Color)

The LCDA board supports interconnection between the μATX board and FP
board. Two internal USB ports come from the μATX board. One USB connects to
a touch panel controller. The other connect to a micro controller on the FP board.
Connectors related to the LCD are also included. The LCDA board consists of the
following blocks:

 Touch-panel controller

 Rotary encoder (signal goes to the FP board)

 LCD back light controller

 Connector to LCD

Multi-Input/Output (MIO)

Board

The MIO board coordinates the flow of data through the Windows PCI port from
various devices that communicate with the μATX system. The devices include the
display system, GPIB, TekLink, and data flow (PCIF) path to the waveform
generator system. An EEROM on this board is used to store the instrument setting
and calibration data. The MIO board consists of the following blocks:

 PCI controller

 GPIB controller

 LCD display controller (ATI Mobility-MI)

 PCI target adapter

 PLD140 (Xilinx FPGA)

 EEPROM for calibration data storage

 TekLink interface

AWG5000 Series Service Manual 2-3

Theory of Operation

Front Switch (FSW) Board

Front Connector (FCON)

Board

Display Panel

Touch Panel

Processor (μATX ) B o ard

The FSW board provides interconnection between the Standby switch and μAT X
board. It includes an LED driver.

The FCON board provides front-panel connections of the USB ports and the DC
output. It includes common mode filters that suppress EMI radiation on the USB
signal.

The active-matrix LCD display is fully controlled by Windows drivers. It is
controlled by the ATI Mobility-M1 micro circuit on the MIO board. The display
has a 1024 x 768 resolution. Brightness is controlled by the intensity of the
backlight.

The touch information from the touch screen is processed by Windows drivers,
actively placing 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 five-wire 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, including 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. Video display data is transferred
to the MIO board through the 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

2-4 AWG5000 Series Service Manual

The power supply CVR460 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 ZWQ130 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.

Theory of Operation

Power (PWR2) Board

CLK1G Board

AWG1 G B o a rd

The PWR2 board provides DC power to the fans, HDD, CD Drive, μATX b o a rd ,
MIO board, OUT1G board, and AWG1G board. All the power comes from the
CVR460 module and the ZWQ130 module. The fan control circuit has a thermal
sensor on this board. DC voltage to the fans is controlled relative to the sensed
temperature. DC-DC converters are included for generating different DC voltages.

The CLK1G board provides a 600 MHz to 1200 MHz clock to the AWG1G board.
The clock input accepts 600 MHz to 1200 MHz clock signals from an external
signal source. The reference clock input accepts 5 MHz to 800 MHz reference
clock signals from an external signal source. The 10 MHz reference output can be
used for synchronizing frequency between two or more instruments. The CLK10G
board consists of the following blocks:

 VCO (600 MHz to 1200 MHz)

 Fractional-N PLL

 10.0 MHz TCXO (reference oscillator)

 External reference input

The AWG1G board generates arbitrary waveforms based on the waveform
memory and the sequence memory. There are two types of PLDs (Xilinx FPGA)
on the board. One is an AWG controller called PLD121 which interfaces to/from
the MIO board. The other is a memory controller called PLD120 which generates
waveform patterns. Waveform data is stored in ZBT type SRAMs. The sequence
memory is included in the memory controller PLD. The AWG1G board consists of
the following blocks:

 1.2 GS/s DAC (AD9736)

 8 channels 8:1 MUX (TEK0015 ASIC)

 PLD120 (Xilinx Virtex-4 FPGA) as a memory controller

 PLD121 (Xilinx Virtex-4 FPGA) as an AWG controller

 ZBT type SRAM for the waveform memory

 28 bits digital output driver

 Marker output driver

 Trigger and event inputs

 DC output

 DC-DC converter

Checking the Power

Supply Voltages

To check the power supply voltages, power on the instrument and connect the (–)
lead of a multi-meter to chassis ground.

To measure the output voltages of the power supply, check the voltages at J104 on
the PWR board with the digital multimeter and compare each reading to the values
listed in Table 4-4. If the voltages are within the allowance, your power supply is
functional.

Instrument Diagnostics

The primary diagnostics for the instrument are accessible through the AWG
application software. The instrument diagnostics check the basic functionality of
analog outputs at every power on. The instrument diagnostics run after Windows
has booted up and run its own set of system checks. If any failures occur at power
on, a pop-up message indicates that a failure has occurred and provides an error
code. Table 4-8 lists diagnostics error codes, Table 4-9 lists calibration error codes,
and Table 4-10 lists hardware error codes.

The power-on tests ensure that the hardware is installed and can be accessed by the
software. The tests provide limited diagnostic information, and provide no
performance information.

To run the instrument Diagnostics manually, do these steps:

1. Turn off all other applications.

2. From the menu bar, select System and then select Diagnostics...; the

Diagnostics dialog box appears (see Figure 4-26).

3. In the dialog box, confirm that all the check boxes are selected. If they are not
all selected, click Select All.

4. Click Execute to execute the diagnostics.
