Description: 10 MHz DDS Function Generator
                                    This Programmable Function Generator uses direct digital
synthesis to provide high performance and extensive
facilities at a breakthrough price. It can generate a
variety of waveforms between 0.1 mHz and 10MHz with a
resolution of 7 digits and an accuracy better than 10ppm.
Direct digital synthesis for accuracy & stability
Direct digital synthesis (DDS) is a technique for generating
waveforms digitally using a phase accumulator, a look-up
table and a DAC. The accuracy and stability of the resulting
waveforms is related to that of the crystal master clock.
The DDS generator offers not only exceptional accuracy-and
stability but also high spectral purity, low phase noise and
excellent frequency agility.
A wide range of waveforms
High quality sine, square and pulse waveforms can be
generated over the full frequency range of 0.1 mHz to 10MHz.
Triangle waveforms, ramp waveforms and multi-level
squarewaves can also be generated but with limitations as to
the maximum useable frequencies.
Variable symmetry/duty-cycle is available for all standard
Arbitrary waveform capability
Arbitrary waveforms can be loaded via the digital interfaces
and then used in a similar way to the standard waveforms.
Up to five arbitrary waveforms of 1024 10-bit words can be
stored in non-volatile memory. The waveform clock is
27.48MHz maximum.
This facility considerably expands the versatility of the
instrument making it suitable for the generation of highly
complex waveform patterns.
In addition, numerous “complex” waveforms are pre-defined in
ROM, including commonly used waveshapes such as sinex/x,
exponentially decaying sinewave, etc.
All waveforms can be swept over their full frequency range
at a rate variable between 10 milliseconds and 15 minutes.
The sweep is fully phase continuous.
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. Two sweep markers
are provided.
Amplitude Modulation is available for all waveforms and is
variable in 1% steps up to 100%. An internal AM source 4s
incorporated. Alternatively modulation can be controlled
from an external generator.
Frequency Shift Keying provides phase coherent switching
between two selected frequencies at a rate defined by the
switching signal source.
The rate can be set from dc to 50kHz internally, or dc to
1MHz externally.
