Introduction
This range of synthesized programmable arbitrary waveform generators have the
following features:
• 1, 2
or 4 independent arb channels
• Additional D
C to 50MHz fixed amplitude sine and squarewave outputs on 2- and
4-channel instruments
• Up to 1
00 MHz sampling frequency
• Sinewaves up to 40
MHz, squarewaves up to 50 MHz
• Output level
2.5 mV to 10 V p-p into 50 Ω with 12 bit vertical resolution
• 1 M poi
nts horizontal resolution per channel
• Co
mpact Flash card for non-volatile waveform memory
• Waveform
linking, looping and sequencing
• Inter-channel triggering, summing,
modulation and phase control
• GPIB, RS232
and USB interfaces
The instruments use a combination of direct digital synthesis and variable clock
techniques to
provide high performance and extensive facilities in a compact package.
They can generate a wide variety of waveforms between 0·1 mHz and 50 MHz with high
resolution and accuracy.
Arbitrary waveforms may be defined with 12
bit vertical resolution and from 8 to
1,048,576 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. Alternatively, an
external arb clock may be used at frequencies up to 50 MHz.
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 the arbitrary waveform creation
software supplied. This 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 can be downloaded via the RS232, GPIB or USB interfaces, or they can be
transferred to the generator on a removable memory card, written to by the PC using the
USB-connected card reader/writer provided.
Up to 500 different waveforms may be stored with the length and name specified by the
user; the total size of all the wavefor
ms stored is limited only by the size of the memory
card. Waveforms may be linked together to form a sequence of up to 1024 steps. Each
waveform may have a user defined repeat count from 1 to 32,768.
