Description: 40MHz Arbitrary Waveform Generator
                                    This Synthesized Programmable Arbitrary Waveform Generator
uses a combination of direct digital synthesis and phase
lock loop techniques to provide high performance and
extensive facilities in a compact instrument. It can
generate a wide variety of waveforms between 0-1 mHz and
16MHz with high resolution and accuracy
Arbitrary waveforms may be defined with 12 bit vertical
resolution and from 4 to 65536 horizontal points. In
addition a number of standard waveforms are available
including sine, square, triangle, ramp and pulse.
Arbitrary waveforms may be replayed at a user specified
waveform frequency or period, or the sample rate may be
defined in terms of period or frequency.
Extensive waveform editing features between defined start
and end points are incorporated, including waveform insert,
point edit, line draw, amplitude adjust and invert. More
comprehensive features are available using WaveForm DSP
arbitrary waveform creation software supplied. Wave Form DSP
is a powerful Windows-based design tool that enables the
user to create waveforms from mathematical expressions, from
combinations of other waveforms, freehand, or using a
combination of all three techniques. Waveforms created in
this way are downloaded via the RS232 or GPIB interfaces.
Up to 50 waveforms may be stored with the length and name
specified by the user. Waveforms may be strung together to
form a sequence of up to four steps. Each waveform may have
a user defined repeat count from 1 to 32768.
All waveforms can be swept over their full frequency range
at a rate variable between 30 milliseconds and 15 minutes.
Sweep can be linear or logarithmic, single or continuous.
Single sweeps can be triggered from the front panel, the
trigger input, or the digital interfaces. A sweep marker is
Amplitude Modulation is available for all waveforms and is
controlled from an external generator via the Ext VCA input.
All waveforms are available as a Triggered Burst whereby
each active edge of the trigger signal will produce one
burst of the carrier. The number of cycles in the burst can
be set between 1 and 1048575. The Gated mode turns the
output signal On when the gating signal is true and Off when
it is false. Both Triggered and Gated modes can be operated
from the internal Trigger Generator (0.005Hz to 50kHz), from
an external source (dc to 1 MHz) or by a key press or remote
The signals from the REF IN/OUT socket and the SYNC OUT
socket can be used to phase lock two or more generators.
This can be used to generate multi-phase waveforms or locked
waveforms of different frequencies.
The generator parameters are clearly displayed on a backlit
LCD with 4 rows of 20 characters. Softkeys and sub menus are
used to guide the user through even the most complex functions.
AH parameters can be entered directly from the numeric
keypad. Alternatively most parameters can be incremented or
decremented using the rotary control. This system combines
quick and easy numeric data entry with quasi-analogue
adjustment when required.
The generator has, as standard, both RS-232 and GPIB
interfaces which can be used for remote control of all of
the instrument functions or for the down-loading of
arbitrary waveforms; the GPIB interface conforms to IEEE-488.2.
