• Additional DC to 50MHz fixed amplitude sine and squarewave outputs on 2- and
• Up to 100MHz sampling frequency
• Sinewaves up to 40MHz, squarewaves up to 50MHz
• Output level 2.5mV to 10Vp−p into 50Ω with 12 bit vertical resolution
• 1M points horizontal resolution per channel
• Compact Flash card for non−volatile waveform memory
• Waveform linking, looping and sequencing
• Interchannel triggering, summing, modulation and phase control
• GPIB, RS232 and USB interfaces
The instrument uses a combination of direct digital synthesis and variable clock techniques to
provide high performance and extensive facilities in a compact instrument. It can generate a wide
variety of waveforms between 0·1mHz and 50MHz with high resolution and accuracy.
Arbitrary waveforms may be defined with 12 bit vertical resolution and from 8 to 1048576
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 50MHz.
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 transferred directly 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 waveforms 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 32768.
All waveforms can be swept over their full frequency range at a rate variable between 1
millisecond 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 provided.
Amplitude Modulation is available for all waveforms and is controlled from the previous channel or
from an external generator via the MODULATION input socket.
Signal Summing is available for all waveforms and is controlled from the previous channel or from
an external generator via the SUM input socket.
