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

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

Fans

Power (PWR) Board

2-4 AWG7000 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.

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.

The PWR board provides DC power to the fans, HDD, CD Drive, µATX bo ar d ,
MIO board, and AWG10G board. All the power comes from the CVR460 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.

Theory of Operation

CLK10G Board

AWG10G Board

The CLK10G board provides a 5 GHz to 10 GHz clock to the AWG10G board.
Two clock outputs go to the CH1 and CH2 DAC. The clock output to CH2 should
be terminated for 1 channel models. The clock input accepts 5GHz to 10 GHz 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:

 YIG oscillator (5GHz to 10 GHz)

 Fractional-N PLL

 10.0 MHz TCXO (reference oscillator)

The AWG10G 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 PLD131 which interfaces to/from
the MIO board. The other is a memory controller called PLD130 which generates
waveform patterns. Waveform data is stored in ZBT type SRAMs. The sequence
memory is included in the memory controller PLD. The AWG10G board consists
of the following blocks:

 10 GS/s DAC (HFD205 ASIC)

 8 channels 8:1 MUX (TEK0015 ASIC)

 PLD130 (Xilinx Virtex-2 FPGA) as a memory controller

 PLD131 (Xilinx Virtex-2 FPGA) as an AWG controller

 ZBT type SRAM for the waveform memory

 Inter-channel phase detector

 Trigger and event inputs

 DC Output

 DC-DC converter (1.5 V and 2.5 V power supply)

OUT10G1 Board for

Standard models

OUT10G2 Board for

Option 02/06

The OUT10G1 board provides analog and marker outputs to the front-panel
connector. Amplitude, filter, offset, and On/Off controls are added to the analog
outputs. High/Low voltage and On/Off controls are added to the marker outputs.
The OUT10G1 board consists of the following blocks:

 Analog output amplifier

 Marker output driver

 Selectable low-pass filter

 Selectable attenuator

 Voltage monitor

 Controller PLD

The OUT10G2 board uses the same raw board as the OUT10G1 board. The
difference is that the OUT10G2 board has no analog output circuitry. For Option
02 and Option 06, the analog signal path is on the relay module. The OUT10G2
board has an analog voltage monitor. The OUT10G2 board consists of the
following blocks:

 Marker output driver

 Voltage monitor

Relay Module (Option 02

and Option 06 only)

 Coax switch driver

 Controller PLD

The relay module provides switches for analog outputs. For Option 02, the relays
switch the analog outputs on and off. For Option 06, the relays switch the
interleaving and the analog outputs on and off. An RF power combiner is used for
mixing channel 1 and 2 signals. The output of the power combiner goes to the
Interleave output.

Adjustment Procedures

Adjustment Procedures

This section contains information about instrument adjustment. Only qualified
personnel should perform adjustment procedures. Read the Service Safety
Summary and the General Safety Summary before performing any service
procedures.

NOTE. Before performing adjustment procedures, you must warm up the arbitrary

waveform generator at least 20 minutes in an ambient temperature between 20 °C
and 30 °C. Adjustments performed before warm-up or outside this temperature
range may result in poor performance.

Adjustment Interval

If the instrument fails performance tests (refer to the AWG7000 Series Arbitrary
Waveform Generators Technical Reference Manual), then adjustment may be

required.

If periodic calibration is one of your requirements, a general rule is to verify
performance and make adjustments (only if needed) every 2000 hours of operation
or once a year if the instrument is used infrequently.

Adjustment After Repair

After removal and replacement of a module, you must perform the Performance
Verification procedure, found in the AWG7000 Series Arbitrary Waveform
Generators Technical Reference Manual. The Technical Reference PDF manual is
included in the Product Documentation CD. This manual is also available on the
Tektronix Web site (www.tektronix.com/manuals).

Saving the Calibration

Results to EEPROM

To perform individual calibrations, click the calibration buttons, starting with
10MHz Reference..., and the corresponding calibrations are executed.

To perform all calibrations in one step, click Execute All Calibrations and all
calibrations are executed in order starting from the top. However, since data timing
calibrations are quite time consuming, it is acceptable to perform only Step 4
(Magic Cal. -2), which depends on the instrument power supply, and skip the other
steps. Instead of performing all the steps in the data timing calibration, restore and
use the calibration constants obtained by the ATS (Auto Test System) at the factory
or during servicing. The following procedures assume that this method will be
used.

When the calibration has been performed and the results are saved to the EEPROM
(regardless of the item, all results are saved to the EEPROM on the MIO board),
the flag under Is Calibrated will be set to TRUE. If the calibration was successful,
the Status field will display PASS. If the calibration failed, FAIL will be displayed.

There are two types of calibration: Self calibration and Manual calibration.

 Self calibration – The instrument performs the calibration item and ends

automatically.

 Manual calibration – This calibration item requires external devices listed on

Table 3-1 and manual data input.

A warning message is displayed if you click a calibration button without waiting
for 20 minutes after the instrument powered on. Click the Cancel button and allow
at least 20 minutes for the instrument to warm up.

This is a self calibration. The YIG for the internal clock source controls the
frequency by the main coil (tuning coil) and the FM coil currents. The sensitivity
differs between individual YIGs, this calibration is required to set the precise
frequency.

This is a self calibration. The instrument features high-speed communication called
IPC (Inter PLD Communication) between the internal Memory Controller and the
Awg Controller. This calibration is required to ensure the optimum timing to
enable the IPC in all frequency settings. Failing to perform this calibration may
disable access to the waveform memory and/or make the AWG board diagnostics
cause an error.

The instrument operates at extremely high speeds between the waveform memory
on the AWG board and the Memory Controller, between the Memory Controller
and TEK0015, and between TEK0015 and HFD205.

This calibration is required to ensure the optimum timing to enable waveform
outputs in all frequency settings. Failing to perform this calibration may not only
disable normal waveform outputs, but may also make the waveform memory
diagnostics cause an error.

3-6 AWG7000 Series Service Manual

Adjustment Procedures

This calibration consists of six steps from Step 0 to Step 5, but in this manual,
perform only Step 4 (Magic Cal.-2). Other calibration constants are restored by
using the data acquired by ATS at the factory or during servicing.

Basic steps are to observe output waveforms on the oscilloscope screen, and to
determine the range of abnormal outputs, which appears on the oscilloscope as a
broken waveform, by adjusting the delay in the TEK0015 Data Output.

Troubleshooting

Instrument Diagnostics

The primary diagnostics for the instrument are accessible through the AWG
application software. The Instrument diagnostics check the basic functionality of
analog and marker output 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 4-6 lists diagnostics error codes, Table 4-7 lists calibration
error codes, and Table 4-8 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 4-22).
