Sundance SMT399-160 - Manual (Page 8)

3 Examples of application.
The SMT399-160 module can be used in the following application:
-
Radio systems. Compatible with Sundance’s TIM Modules, it can be combined with
DAQ modules such as ADCs and DACs, as a clock generator. The SMT399-160 fine-
tuning makes it even more suitable for such platform to generate up-to-four
synchronised and/or quadrature signals.
-
Test systems. It is sometimes very helpful to have a signal generator capable of
generators various frequencies to evaluate some radio system. Fast hopping is the key
word here. Dual tone signals are useful to characterise a receiver system to evaluate
its capabilities of receiving signals close to each other in frequency. DDSs also to
generate a ramp, a pattern or a frequency sweep.
-
Programmable system. As most of system, it a very important top control every part
of a system. The SMT399-160 is fully controllable via software.
-
Etc…
As both pairs of DDSs are synchronised and coupled master/slave, the module can generate
90-degree phase shift signals and be part of a quadrature modulator system.
