Product Overview

Product Description

The AWG615 Arbitrary Waveform Generator is a waveform generator that can
generate simple and arbitrary waveforms, one–channel differential output arbitrary
waveforms, and function generator waveforms.

The AWG615 Arbitrary Waveform Generator allows you to create sine, triangle,
square, ramp, and complex waves, as well as direct current and noise signals. You
can also set waveform attributes such as frequency, amplitude, and offset.

This instrument contains a hard disk drive, a 3.5–inch floppy disk drive, and
Ethernet interface for storing and recalling waveform data and instrument settings.

You can control the instrument remotely by sending commands through both the
GPIB and 100/10BASE–T interfaces, as well as transfer waveform data directly
from a digital storage oscilloscope to the AWG615 Arbitrary Waveform Generator
using the GPIB interface. This enables you to use the instrument in combination
with other measurement equipment and a computer.

Electrical Specification

Table 1-1: Run modes

Characteristics Description

Continuous Waveform is continuously output in this mode. When a sequence is defined, waveforms are

sequentially or repeatedly output in the order defined by the sequence. The extended
sequence functions such as trigger input, event jump, and so on are neglected in this mode.

Triggered Waveform is output only once when a trigger event is created. A trigger signal is created by

the external trigger input signal, GPIB trigger command, and/or pressing the front–panel
FORCE TRIGGER button. The extended sequence functions such as trigger input, event
jump, and so on are neglected in this mode.

Gated The waveform is output in the same way as in the continuous mode only when the gate is

opened. The gate is opened by the gated signal.

Note that the output is made from the top of the first waveform for every gate period. The clock
signal continuously outputs from the connector outside the gate period.

Enhanced The waveforms are sequentially or repeatedly output according to the procedures defined in

the sequence. All extended functions such as trigger input, event jump, and so on are effective
and waveforms are controlled for output by this functions in this mode.
Event jump and Software jump are disabled in Synchronous Operation mode.

Table 1-2: Extended Operation

Characteristics Description

FG operation This mode provides user-friendliness like the conventional function generator. The output

waveforms are Sine, Triangle, Square, Ramp, Pulse and DC waveform. AWG615 is in AWG
mode when this mode is not selected.

Waveform Mixing operation This mode provides the function for mixing two-signals digitally.

Synchronous Master operation This mode provides the setup for using as a Master instrument on Synchronous Operation.

Synchronous Slave operation This mode provides the setup for using as a Slave instrument on Synchronous Operation.

Operating Temperature

The AWG615 Arbitrary Waveform Generator operates with any line voltage from
90 to 250 VAC
either of which may be used throughout the line voltage and frequency ranges. The
two fuses are not interchangeable as each requires a different fuse cap.

Memory modules with on–board batteries allow the AWG615 Arbitrary
Waveform Generator to retain only internal clock data upon loss of the AC power
source.

To set the date and time in the waveform generator, see the Reference:Internal
Clock (Date and Time) section of the AWG615 Arbitrary Waveform Generator
user manual.

The following environmental requirements are provided to ensure proper operation
and long instrument life.

Operate the Waveform Generator where the ambient air temperature ranges from
10° C to +40° C (50° F to +104° F). Store the Waveform Generator at ambient
temperatures from -20° C to +60° C (-4° F to +140° F). After storage at
temperatures outside the operating limits, allow the chassis to stabilize to a safe
operating temperature before applying power.

requirements for air flow around the instrument:

Rear 7.5 cm (3 in)
Left and right 15.0 cm (6 in)
Top and bottom 2 cm (0.8 in)

(The feet on the bottom of the instrument provide the required clearance when
set on a flat surface.)

2-4 AWG615 Service Manual

Preparation for Use

NOTE. If the air flow is restricted and the internal temperature of the AWG615

Arbitrary Waveform Generator exceeds the proper operating temperature range,
the instrument temporarily shuts down to protect the internal modules from
overheating. To prevent temporary shutdown of the AWG615 Arbitrary Waveform
Generator do not restrict air flow through the chassis.

If the AWG615 Arbitrary Waveform Generator shuts down unexpectedly, improve
the ventilation around the waveform generator and wait a few minutes to allow it
to cool down; then switch the power on again.

You cannot power on the instrument when the ambient temperature exceeds the
instrument temperature operation range. Wait until the instrument cools down, or
the ambient temperature decreases to valid operating temperatures, before turning
on the instrument again.

To use the numeric keypad to enter a value, position the caret to where you want
to change a value, and then push a keypad button. If you want to enter a unit value
labeled in blue just above each numeric button, push or hold down the SHIFT
button, and then push the corresponding numeric button.

To enter or change more than one character, move the caret to the next position to
change. When you are done entering values, push the ENTER button to confirm
the changes and enter them into the instrument. For example, to enter 200.5 µs,
push 2, 0, 0, ., 5, SHIFT and 4 (µ) buttons in this order.

When you enter a value larger than the maximum value in the range for the
parameter, the parameter will be set to the maximum value. When you enter a value
smaller than the minimum value, the minimum value will be set in the parameter.
To set to the maximum or minimum value, enter a larger value or smaller value.
This is useful when you do not know the range that can be set.

Note that the current unit is always kept when you just use the ENTER after
entering digits. For example, suppose that the Clock is currently set to100.0 MS/s.
When you press the 5, 0 and ENTER buttons in this order, the Clock will be set to

50.0 MS/s. To set the Clock to 500 kS/s, press 0, ., 5 and ENTER buttons, or 5, 0,

Loading a Waveform File

to Output

Do the following steps to load a waveform file into the Setup screen:

1. Push the Waveform/Sequence bottom menu button.

This opens the Waveform/Sequence side menu.

2. Push the Load... side button. The instrument opens the Select File list as shown

in Figure 2-20.

Figure 2-20: Select File dialog on the Load menu

3. Use the general purpose knob or y and b arrow buttons to select the file name

to load. If the file you want to load is located in a different drive or directory,
use the side menu buttons to change the current drive.

4. Push the ENTER front–panel button or OK side button. The instrument loads

the file and displays the file name in the selected channel file icon. Push the
Cancel side button to exit the file load process.

The procedures above explains how to load a waveform or pattern into the
waveform memory, and/or sequence file into the sequence memory, which will be
scanned to output. The waveform memory, sequence memory and the edit buffer
are completely independent. So, you can edit a waveform, pattern, sequence or
equation/text while outputting an another waveform or sequence.

However, when you push SETUP (front–panel)!Waveform/Sequence
(bottom)!Edit (side) to copy the waveform in the waveform memory to the edit

Operating Basics

buffer, you must save the currently edited waveform, pattern, sequence or
equation/text into a file.

You can enter into the QUICK EDIT mode only from the waveform editor. When
you enter into the quick edit mode, the instrument copies the data in the edit buffer
into the undo buffer. All the changes you make immediately reflect to the data in
the edit buffer, and also to the data in the waveform memory if that data is being
loaded to output.

Before loading, you can view a waveform or pattern. Refer to Quick View on page
2-35 for more detail.

Viewing a Waveform

To view the loaded waveform file, push the View side menu button. The instrument
opens a window on the screen that displays the waveform, as shown in Figure 2-21.
Push the OK side menu button or ENTER front–panel button to close the view
window.

Figure 2-21: Viewing a file in the Setup screen

Note that the View function does not display the waveform in the waveform
memory, but displays the waveform in the file that you specified. Even though you
change the waveform with the editor and update the waveform memory, the View
function still displays the waveform before the update unless you save the file.

Saving and Restoring

Setup Parameters

The waveform or pattern file contains only the waveform and clock information.
When you load a waveform or pattern file, the output signal will use the current
instrument setup parameters.

To save you from doing a manual setup procedure each time you load a waveform,
the AWG615 Arbitrary Waveform Generator lets you save setup parameters into a
setup file. You can then restore the saved settings for use with waveforms.

The setup parameters of the AWG mode and the Extended Operation mode are
saved in a setup file. When a setup file is restored, settings in both AWG mode and
Extended Operation mode will replace the contents of a setup file.

Do the following steps to save the current setup parameters:

1. Push SETUP (front)!Save/Restore (bottom)!Save Setup (side).

The Input Filename dialog box appears.

2. Enter a setup file name.

The setup file name must have the extension .set.

3. Push the OK side button.

The setup information is saved to the designated file.

Do the following steps to restore setup parameters from a file:

1. Select SETUP (front)!Save/Restore (bottom)!Restore Setup (side).

The message box displaying Restoring setup destroys current settings.
appears. The instrument then opens the Select Setup Filename dialog box.

2. Enter or select the setup file name to load.

3. Push the OK side button to load the file and restore the setup parameters, or

push the Cancel side button to exit the restore process without loading the
setup file.
